    Food safety is about trust. Good processing, retail and food service companies choose suppliers that they trust - and sometimes that includes demonstrating they can manage risks during some sort of an audit or inspection.
    Patrons choose food based on a whole bunch of things like price, taste, ethical philosophy and trust that they aren't going to get sick -- with not all that much safety information to go on.

    In most jurisdictions, selling food means meeting some sort of licensing/inspection requirement. In better locales health authorities tell people about how individuals managed food safety the last time someone checked - and post the results online or in the window (even better if they have QR codes). I had coffee with a colleague last week and he asked me about North Carolina's grade posting system. I said I liked the dialogue and interest it generates but that it's hard to make a decision based on the sign - there are lots of limitations. I can't tell whether the business lost points because of a bunch of little things like broken tiles or no hot water in the handwashing sinks (that I don't really care about) or whether someone showed up to work barfing (which I do care about).

    He just said, "I don't eat at Jersey Mike's because of the grade posting. They had a 94 (relatively low in NC -ben) for a couple of months."

    Having poor inspection results can affect patrons' trust - so can outbreaks.

    In Jersey, land of Springsteen, Bon Jovi, Snooki and Jwow and Princeton, NJ health folks have pointed to a Mercer County Panera Bread outlet as one of the potential spots where a January 2012 norovirus outbreak was spread. According to Samantha Costa of The Times, Panera was reported as a common spot that a bunch of the ill college kids ate.

    During the peak of the norovirus outbreak at colleges here this winter, as many as 150 Princeton University students could have been exposed to the illness at a local eatery, public health officials said this week.The virus that sickened more than 400 students at colleges and universities throughout Mercer County may have been spread through many venues, but health officials in Princeton suspect many Princeton University cases originated at Panera Bread on Nassau Street. In late January, the health department removed five workers in the restaurant from food handling after discovering that many students with the illness had eaten there.

    “There might have been upwards of 150 different students, and there was no realistic way to get a total number of food histories on those students,” Princeton Regional Health Department Director David Henry said. All of those students had eaten at Panera, but there were many other potential sources of the virus that also may have been involved, health officials said.

    Jackie Brenne, a spokeswoman for Panera, said that despite the precautions, “no Panera associates were found to be ill. Panera managers did review safety and illness policies with all cafe associates.”The health department report said inspector Randy Carter spent about an hour at Panera Bread, tracking down the food histories of where students ate and listed common foods they ate at Panera Bread to rule out salmonella (not sure why Salmonella was focused on here? -ben).

    However, the students’ eating habits pointed to many retail food establishments, the report said.“In those particular cases, we can’t label or narrow it down to one or two food establishments. It was a community outbreak and Panera and some of the other places just ended up being victims of the norovirus,” Henry said. “We don’t know the one place. All we know is when we have a situation we have to contain it.”Nassau Street is frequented by many Princeton University and Rider University students alike, the department said. Rider’s Westminster Choir College campus is in Princeton.

    The ripeness of fruit could determine how food poisoning bacteria grow on them, according to scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week. Their work could lead to new strategies to improve food safety, bringing many health and economic benefits.

    A wide range of fresh produce has been linked to outbreaks of Escherichia coli and Salmonella enterica including melons, jalapeño and serrano peppers, basil, lettuce, horseradish sprouts and tomatoes. Researchers at Imperial College London are looking at how these bacterial pathogens latch onto fruits and vegetables and establish themselves in the first place.

    They have discovered that strains of Salmonella behave differently when attached to ripe and unripe tomatoes. "Bacteria that attach to ripe tomatoes produce an extensive network of filaments, which is not seen when they attach to the surface of unripe tomatoes. This could affect how they are maintained on the surface," explained Professor Gad Frankel who is leading the research. "We are not completely sure yet why this happens; it might be due to the surface properties of the tomatoes or alternatively the expression of ripening hormones."

    Results like these should feed submissions called for by Food Standards Australia New Zealand regarding the safety of fresh produce including fruits, vegetables, mushrooms, tree nuts and edible flowers.

    FSANZ Chief Executive Officer Steve McCutcheon said this work was part of a series of national food safety standards which apply throughout the food supply chain – from paddock to plate.

    “The majority of fresh horticultural produce grown in Australia is produced under industry-based food safety schemes. However, food safety hazards can occur which can cause illness in the community and costs to industry.

    “FSANZ is exploring if regulatory or additional non-regulatory measures are needed to manage these hazards in conjunction with existing schemes.”

    Comments are invited from government agencies, industry and consumers on the Assessment Report.

    The closing date for submissions is 21 May 2012.

    The Daily News-Miner reports a bill introduced by North Pole Republican Rep. Tammie Wilson would do away with much of the state’s safety regulations for food sold directly to consumers in an attempt to grow Alaska’s local food industry and farmers markets.

    That has health officials worried. House Bill 202, which was heard in the House Labor and Commerce Committee this week, would remove safety regulations not only for the traditional farmers market fare but also for potentially hazardous foods like seafood, shellfish, poultry, meat, dairy and any other processed foods.
    Currently, the Department of Environmental Conservation has no regulations for direct-to-consumer food sales for raw fruits and vegetables, syrup, honey and jam. But the state does have safety regulations on most other processed foods and raw foods where there’s a potential for dangerous bacteria to make it to the consumer.

    But Wilson feels that expenses like permits and equipment are stifling the development of local food. Instead, she said the consumer should take responsibility for the food they eat.

    “We just think that there’s something called responsibility that is here,” she said during the committee hearing. “I don’t think government is there to keep us safe from absolutely everything, you can’t protect everybody from everything.”

    She said, instead, that the state should take an education-based approach to food safety.

    Wilson’s bill would require sellers to provide a card that alerts the consumer that “This product has not been inspected by any governmental agency and may be harmful to your health.”

    Environmental Health Director Kristin Ryan who testified against the bill’s sweeping changes, said, “People buy food under the assumption that it’s safe to eat. Yes, people should have personal responsibility. But when there’s some clear risk, it’s our responsibility to protect against that risk.”

    A vaccine could be developed to prevent Campylobacter being carried in chickens according to an American scientist presenting his work at the Society for General Microbiology's Spring Conference in Dublin.

    Foodborne illness costs the UK an estimated £2 billion each year. Campylobacter is the leading cause of foodborne illness and is responsible for about 30% of cases in the UK. Campylobacter jejuni was responsible for more than 371,000 estimated cases in England and Wales in 2009, resulting in more than 17,500 hospitalizations and 88 deaths.

    Scientists at Washington State University are studying the maternal antibodies that are passed from hens to their chicks. "These antibodies protect chicks from becoming colonized by Campylobacter in the first week of life," explained Professor Michael Konkel who is leading the research. "Our group has now identified the bacterial molecules that these antibodies attack, which has given us a starting point for a vaccine against Campylobacter," he said. "We have already found that chickens injected with these specific molecules – found on the surface of Campylobacter jejuni – produce antibodies against the bacterium. This response partially protects them from colonization."

    "Preventing contamination of poultry at slaughter has not been effective at reducing illness in humans. It has been shown that about 65% of chickens on retail sale in the UK are contaminated with Campylobacter," explained Professor Konkel. "Ideally, the best way to prevent contamination is to stop chickens on the farm from becoming colonized with this microorganism in the first place, which could be achieved by vaccination. Our goal within the next 6 months is to test a vaccine for chickens that will reduce Campylobacter colonization levels. There's still a long way to go, but I'm confident our lab and others are moving in the right direction."

    Beef Products, Inc. ran a full-page ad in the Wall Street Journal Friday along with copy by Nancy Donley, President, STOP Foodborne Illness talking about the role of ammonia hydride and food-grade antimicrobial sprays in hamburger production, along with some choice words from Eldon Roth, CEO of BPI, about the "campaign of lies and deceit that have been waged" by the "entertainment media, tabloid journalists, so-called national news." He says the "misinformation campaign" may result in the "loss of over 3,000" jobs. He also says that the "lean beef" from his company has been in over 300 billion meals.

    The choice of a print media outlet appealing to the business elite raises some issues: do many people who eat hamburger from grocery stores or school cafeterias routinely read the Wall Street Journal? Is print media the best way to reach Americans? Who are the PR geniuses that came up with this strategy and why do they keep telling BPI to blame the media for reporting on what is a right-to-know issue?

    New York-based Wegmans said Friday it will stop selling ground beef that includes the ammonia-treated filler known as "pink slime in response to customer concerns caused by "sensationalism" over the product.

    A spokesman for Cargill, the leading U.S. ground beef producer, told The Daily that "pink slime" is "pretty much over." And that "the industry produces 800 million pounds of finely textured beef every year. We'll likely have to raise an additional 1.5 million head of cattle to make up for the loss.”

    As predicted when USDA abdicated leadership and left things pink and slimey up to schools, PTA meetings are now seemingly dominated by fillers rather than meat.

    The Boston school district, among others, has taken the step of purging all ground beef from its menus to immediately get rid of pink slime. Other districts, like the New York City schools, have begun phasing out ground beef containing the additive from their lunchrooms.

    Michael Peck, the director of food and nutrition services for the Boston schools, said the district had decided to hold and isolate its entire inventory of ground beef, leaving over 70,000 pounds of beef — worth about $500,000, Mr. Peck estimated — confined to a warehouse until the district knows more about what is in it.

    “It’s another example of the alteration of our food supply,” said Mr. Peck, who is concerned about the use of ammonia hydroxide gas to kill bacteria in the product. “Have we created another unknown safety risk?”

    In Portsmouth, N.H., it was the memory of an E. coli scare over spinach that led Deborah Riso, the district’s nutrition director, to decide she would take no chances.

    “You just pull it because you don’t know,” Ms. Riso said from her office, where she was expunging ground beef from the April school menu. “I had a hamburger bar, so I’m going to do a hot roast beef sandwich. I had a beef or chicken burrito — I’m going to go with the chicken and rice burrito,” Ms. Riso said. “You can still make a nice product without beef.”

    The schools’ exodus is grounded less in science than in instinctive revulsion, said Donald W. Schaffner, director of the Center of Advanced Food Technology at Rutgers University.

    “I don’t see that there is a scientific or health benefit from the point of microbiology or even toxicology,” Dr. Schaffner said of the rush to pull the beef from school menus. “The reason why it’s resonated with people is not so much that it’s unsafe, but the idea that we’re putting ammonia in our food is unpalatable to people.”

    Reuters reports that every time someone calls former U.S. government scientist Gerald Zirnstein a whistleblower, he cringes a little.

    When he coined the term "Pink Slime" to describe the unlabeled and unappetizing bits of cartilage and other chemically-treated scrap meat going into U.S. ground beef, Zirnstein was a microbiologist at the U.S. Department of Agriculture.

    He made the slime reference to a fellow scientist in an internal - and he thought private - email. But that email later became public, and with it came an explosion of outrage from consumer groups.

    "You look through the regulations and a lot of that stuff was never approved for hamburger. It was under the radar," said the 54-year-old Zirnstein, who lives outside Washington, D.C. with his wife and 2-year-old son. "It's cheating. It's economic fraud," he said in a telephone interview.

    Zirnstein, who worked in a meat plant growing up in Kansas, said the situation came to his attention a decade ago. In 2002, he was working as a USDA food scientist and was assigned to a project to determine what was going into ground beef and whether the ingredients met federal regulations.

    At the same time, the beef industry was asking the government to endorse a new product they called "lean finely textured beef" that was largely trimmings typically used for pet food and cooking oil. The trimmings were treated with ammonia to kill dangerous bacteria.

    USDA officials approved the processed product. Zirnstein was disgusted, and made his opinion known to co-workers in an email that called the processed product "pink slime." The email was later released to the New York Times as part of a Freedom of Information request for a 2009 investigative article on food safety. The newspaper article mentioned the slime reference in passing.

    "Nobody did anything (about pink slime). USDA dropped the ball again. The meat industry soft sold it," said Zirnstein, who left USDA and took a job as an industry consultant but now is unemployed. The issue got renewed life when British celebrity chef Jamie Oliver, who advocates for American children to eat healthier food, devoted an episode of his television show to the topic in April last year.

    Oh, and pink slime isn’t used in Canadian burgers – at least according to Health Canada, which says it hasn’t ruled on the product because no one has asked. But Canadians do ship burgers to the U.S. that contain E. coli O157:H7. And get recalled.

    Friday I had to grab a quick lunch, so I joined a colleague at the “UQ Refec” (University of Queensland – that’s in Australia – food court in American lingo) to buy a sandwich. She had one in hand within a few seconds while I picked over the containers. The delicious looking wraps all had sprouts. Some were labeled with all ingredients, including alfalfa, but some were simply called Chicken and Salad and still contained sprouts. I rejected a chicken caesar sandwich because it cost $2 more for the same amount of food. While frantically trying to make a decision, I attempted to explain, in French, the dangers of sprouts and my decision not to eat them. I do enjoy the taste, but there are just too many people getting sick.

    Finally, I settled on a sliced roast pork, shaved carrots and cucumber sandwich. It, too, was $2 more but sprout-free. Apparently gourmet means no sprout filler.

    We returned to our office to discuss work over lunch. I cracked open my sandwich only to realize it was made on chia seed bread. At least the bread was cooked.

    According to the Ottawa Citizen, public health officials have found Salmonella typhimurium in frozen ground beef and Salmonella Heidelberg in raw chicken samples taken from a Lunch Lady franchise that has been linked to an outbreak. At least 50 illnesses in about a dozen elementary schools serviced by the business have been identified.

    Lab tests indicate that an outbreak of salmonella that has sickened 46 children likely came from food served by a lunch caterer that primarily serves schools, according to the city’s health department.

    Samples of frozen ground beef and raw chicken taken from a kitchen belonging to a Lunch Lady franchise on Boyd Avenue tested positive for the stomach bug detected in the children and four adults who’ve been sick enough to seek medical attention in the last two weeks, the department said in a Friday evening statement.

    “The results further point to a link between the outbreak and the ground beef prepared at the caterer, but additional testing is still underway,” the statement said.

    The beef was tainted with salmonella typhimurium and the chicken with salmonella heidelberg, it said, two of the many, many forms of the bacteria. The department’s investigation has pointed particularly to Lunch Lady meat lasagna and beef tacos as foods eaten by people who later got sick.

    The challenge now is to determine whether the meat was contaminated when it arrived at the kitchen or became tainted while Lunch Lady workers handled it. The health department “is in communication with the Provincial and Federal Health and Food Safety authorities to assist in the ongoing investigation and response,” the statement said.

    According to public records, the Boyd Avenue kitchen has been inspected four times since news of the outbreak became public and received a clean report each time, but it could have been just one worker with dirty hands who spread the infection. The kitchen is staying closed, the health department said.

    Four post-outbreak inspections may not be all that representative of what was going on before the cluster of illnesses was identified. Undercooking or cross-contamination between the raw food sources and ready-to-eat foods are potential pathways for the Salmonella. What's unclear from the public health statement is whether either of the strains found are the same as what has been seen in the cluster of illnesses.

    Although things are supossedly getting better, tough economic times since 2008 have led to an increase of folks relying on food banks and soup kitchens. Stories of concerned people distributing donated or leftover food have been common over the past couple of years as communities come together to support those hit hardest.

    I can't imagine how hard it is to be homeless or not have enough money to feed my family. Focusing on safe, nutritious food is moot if the money isn't available to buy groceries. Or if there's no home to take them too. Having a good heart and good intentions doesn't automatically lead to safe meals.

    According to Philly.com the Philadelphia Board of Health has approved new food safety regulations related to groups that feed the homeless outdoors.

    Groups will be required to obtain a permit from the city and to have at least one member receive free food-safety training from the Health Department. The regulations come as the city proceeds with a ban in city parks on feeding the homeless and others who want free meals.

    Further coverage in Bloomberg Businessweek says these new rules are politically-based and food safety is being used to clean up parks.

    Homeless advocates say it’s not the cost that’s bothering them, since many municipalities are offering food-training classes for free. Instead, they’re concerned the bureaucratic intrusions will cause some small operations, such as those that don’t have access to approved kitchens, to shut down.

    [Philadelphia Mayor Michael] Nutter said another policy change that bans outdoor feeding at city parks will increase “the health, safety, dignity and support” for the homeless.

    The city has banned feedings in city parks, except for family picnics and public events, and is considering rules to protect the homeless from foodborne illness. Brian Jenkins [who works for Chosen 300 Ministries Inc] says the requirements, such as preparing items in approved facilities and attending food-safety classes, are a ploy to rid tourist areas of people deemed an eyesore.

    “Jesus didn’t have to go to an approved kitchen,” Jenkins said. “If I have to pay a fine, then I will. I’m still going to feed outside, the way I always have. I’ll just put up a sign that says ‘God’s Family Picnic.’”

    Responsible community members and organizations who are passionate about feeding those less fortunate still need to know about food-related risks and do their best to address them - dealing with a foodborne illness could contribute to an individual's hardship.

    After recurring rumors of an outbreak, raw milk, raw nonfat milk and raw cream produced by Claravale Farm of San Benito County is now the subject of a statewide recall and quarantine order announced today by California State Veterinarian Dr. Annette Whiteford. The quarantine order came following the confirmed detection of campylobacter bacteria in raw cream.

    Consumers are strongly urged to dispose of any product remaining in their refrigerators with code dates of “MAR 27” and earlier, and retailers are to pull those products immediately from their shelves.

    On March 19, Claravale Farm voluntarily ceased distribution of its products after the California Department of Food and Agriculture made a preliminary positive finding of campylobacter in raw cream. The stoppage of distribution included goat milk, as well. No illnesses have been definitively attributed to the products at this time. However, the California Department of Public Health is conducting an epidemiological investigation of reported clusters of campylobacter illness where consumption of raw milk products may have occurred.

    The Romaine-lettuce-served-at-Schnucks-salad-bars E. coli O157:H7 outbreak that sickened 58 people in the Midwest last fall has received the final-write-up treatment from the U.S. Centers for Disease Control, with many questions unanswered.

    In the excerpts below, Chain A is Schnucks, and the farm the lettuce was traced to Farm A, although one Missouri health type at the time said a grower in California was suspected of being connected but records were “insufficient to complete the picture.”

    Yes, there are vast limitations when conducting a food safety outbreak investigation, but the public reporting of this outbreak still reeks of the Leafy Greens Cone of Silence – that the most noticeable achievement since the California Leafy Greens Marketing Agreement was created in the wake of the 2006 E. coli O157-in-spinach mess is the containment cone of silence that has descended upon outbreaks involving leafy greens.

    Things didn’t sound quite right back on Oct. 28, 2011, when St. Louis County health officials first publicly confirmed that the source of the E. coli O157 strain that had sickened 23 people was foodborne, but that the investigation was ongoing. Though retailers had not been asked to pull any food, Schnucks voluntarily replaced or removed some produce in salad bars and shelves, beginning Oct. 26, 2011.

    "Once we heard that the health department had declared an outbreak, we took some proactive steps with our food safety team to switch products out that recent history told us could be potential sources," said Schnucks spokeswoman Lori Willis.

    A Schnucks store, Culinaria in downtown St. Louis, put a sign up on empty shelves that read in part, "Due to a voluntary recall on pre-packed lettuce, we will not be able to produce these pre-made salads. Be assured quality is our main concern. All of the lettuce on the salad bar is fresh and not involved with the recall."

    A table of leafy green related outbreaks is available at http://bites.ksu.edu/leafy-greens-related-outbreaks.

    The U.S. Center for Disease Control reports CDC collaborated with public health and agriculture officials in Missouri, other states, and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Escherichia coli serotype O157:H7 infections linked to romaine lettuce. Public health investigators used DNA "fingerprints" of E. coli O157:H7 bacteria obtained through diagnostic testing with pulsed-field gel electrophoresis (PFGE) to identify cases of illness that may be part of this outbreak. They used data from PulseNet, the national subtyping network made up of state and local public health laboratories and federal food regulatory laboratories that performs molecular surveillance of foodborne infections.

    As of March 21, 2012, 58 persons infected with the outbreak strain of E. coli O157:H7 were reported from 9 states. The number of ill persons identified in each state was as follows: Arizona (1), Arkansas (2), Illinois (9), Indiana (2), Kansas (2), Kentucky (1), Minnesota (2), Missouri (38), and Nebraska (1). Two cases were removed from the case count because advanced molecular testing determined that they were not related to this outbreak strain. Among persons for whom information was available, illnesses began from October 9, 2011 to November 7, 2011. Ill persons ranged in age from 1 to 94 years, with a median age of 28 years. Fifty-nine percent were female. Among the 49 ill persons with available information, 33 (67%) were hospitalized, and 3 developed hemolytic uremic syndrome (HUS). No deaths were reported.

    This particular outbreak appears to be over.

    Collaborative investigative efforts of state, local, and federal public health agencies indicated that romaine lettuce sold primarily at several locations of a single grocery store chain (Chain A) was the likely source of illnesses in this outbreak. Contamination likely occurred before the product reached grocery store Chain A locations.

    During October 10 to November 4, 2011, public health officials in several states and CDC conducted an epidemiologic study by comparing foods eaten by 22 ill and 82 well persons, including 45 well persons who shopped at grocery store Chain A during the week of October 17, 2011. Analysis of this study indicated that eating romaine lettuce was associated with illness. Ill persons (85%) were significantly more likely than well persons (46%) to report eating romaine lettuce in the week before illness. Ill persons (86%) were also significantly more likely than well persons (55%) to report shopping at grocery store Chain A. Among ill and well persons who shopped at grocery store Chain A, ill persons (89%) were significantly more likely than well persons (9%) to report eating a salad from the salad bar at grocery store Chain A. Several different types of lettuce were offered on the salad bar at grocery store Chain A. Of 18 ill persons who reported the type of lettuce eaten, 94% reported eating romaine lettuce. No other type of lettuce or other item offered on the salad bar was reported to be eaten by more than 55% of ill persons.

    Ill persons reported purchasing salads from salad bars at grocery store Chain A between October 5 and October 24, 2011. A total of 9 locations of grocery store Chain A were identified where more than one ill person reported purchasing a salad from the salad bar in the week before becoming ill. This included 2 separate locations where 4 ill persons reported purchasing a salad at each location. For locations where more than one ill person reported purchasing a salad from the salad bar and the date of purchase was known, dates of purchase were all within 4 days of other ill persons purchasing a salad at that same location. Chain A fully cooperated with the investigation and voluntarily removed suspected food items from the salad bar on October 26, 2011, out of an abundance of caution. Romaine lettuce served on salad bars at all locations of grocery store Chain A had come from a single lettuce processing facility via a single distributor. This indicates that contamination of romaine lettuce likely occurred before the product reached grocery store Chain A locations.

    The FDA and several state agencies conducted traceback investigations for romaine lettuce to try to identify the source of contamination. Traceback investigations focused on ill persons who had eaten at salad bars at several locations of grocery store Chain A and ill persons at university campuses in Minnesota (1 ill person) and Missouri (2 ill persons). Traceback analysis determined that a single common lot of romaine lettuce harvested from Farm A was used to supply the grocery store Chain A locations as well as the university campus in Minnesota during the time of the illnesses. This lot was also provided to a distributor that supplied lettuce to the university campus in Missouri, but records were not sufficient to determine if this lot was sent to this university campus. Preliminary findings of investigation at Farm A did not identify the source of the contamination. Farm A was no longer in production during the time of the investigation.

    A keen barfblog reader sent on the below video from ABC news with a new angle on the ongoing pink slime saga.

    AP food writer J.M Hirsch conducts a whats-in-my-beef taste test, in a somewhat unscientific way, and declares that burgers made without lean finely textured beef are yummier than those with it. He declares the no-LFTB one the winner (but the other is apparently a decent burger too).

    Color isn't a good indicator of safety - would have been nice to see Hirsch stick it in (a tip-sensitive digital thermometer that is).

    On a cloudy afternoon in September, Chicago health inspector Charity Okoro arrived at Taste of Peru and began pointing out problems.

    "She comes into the restaurant really mad, really screaming," recounted co-owner Cesar Izquierdo, according to city documents. He said she accused the restaurant of a handful of violations including cross-contamination for leaving an open can of beer, used for cooking, next to an uncut avocado.

    Okoro issued a ticket for about $500 worth of fines but, Izquierdo said, she changed her tone when she learned that he suffers from back problems.

    "Right away she stopped screaming, she stopped everything, you know, she stopped the inspection," he told city officials. He said she assured him she could "fix you up."

    The very next day Okoro was back. But this time as a vitamin saleswoman.

    Izquierdo bought $391 worth of Nutrilite vitamins, according to records. "I was a little intimidated," Izquierdo recalled. "This was the inspector selling them."

    Izquierdo and his wife, Julie, said that after the sale was complete the inspector told them the date of their upcoming reinspection and assured them that everything would be fine. When Okoro arrived on the promised date, she didn't come into the kitchen but issued them a passing grade nonetheless, said Julie Izquierdo.

    The Tribune found three other Rogers Park restaurants where owners say Okoro peddled her vitamins. Yet neither the Izquierdos nor any of those owners complained to the city's Department of Public Health.

    Finally, in November, after much deliberation and loss of sleep, Julie Izquierdo decided to report the incident — along with supporting documents — to an administrative law judge when she went to contest the fines. The administrative judge reversed the fines against Taste of Peru, and a city investigation then led to Okoro's resignation.

    The Chicago Tribune reports it's a sequence of events that lays plain the difficult relationship between the city's restaurants and its regulators. The city says it welcomes complaints from restaurant owners, whom a Health Department spokeswoman called "our eyes and ears."

    But in the course of its investigation, the city did not reach out to any of the restaurants where Okoro tried to sell her vitamins. Meanwhile, some restaurant owners said they assume any concerns they express to the city are likely to fall on deaf ears or, worse, be used against them.

    "There is (an assumption) in food business that they will suffer terrible consequences if they step forward," said Logan Square Kitchen owner Zina Murray, who launched a petition last summer to change Health Department policies but said few restaurants would sign it for fear of angering the city.

    Inspectors, in particular, hold great power in the restaurant world because a bad report or temporary shutdown can cost owners thousands of dollars and jeopardize business.

    “We have the safest food supply in the world. Despite the listeria outbreak, the sheer volume of produce, fresh or processed, that is consumed by the American public with little or no incidence is testimony to that fact.”

    That according to Pete Suddarth, product development and field director of customer relations for Abbott & Cobb Inc., Feasterville, Pa.

    Testify. Fact. Sounds a little spiritual (appropriate since so much of food safety is faith-based).

    The Packer reports that food safety has become a major focus of seed companies and they work to adapt their products to a changing environment and increased market demands.

    The rest of the story was about disease resistance, quality and yield, although Art Abbott, president of Abbott & Cobb, said the firm is working on reducing the heavy netting on cantaloupes to make them less susceptible to moisture absorption. This trait would help to reduce possible pathogen infections.

    May reduce. May.

    Can you seed types do anything about sprout seeds?

    From researchers in Finland, writing in the April edition of Emerging Infectious Diseases. Edited bits below, the complete report is available at http://wwwnc.cdc.gov/eid/article/18/4/11-1310_article.htm.

    Shiga toxin–producing Escherichia coli (STEC) is a pathogen that causes gastroenteritis and bloody diarrhea but can lead to severe disease, such as hemolytic uremic syndrome (HUS). STEC serotype O78:H– is rare among humans, and infections are often asymptomatic.

    A boy born on Oct. 3, 2009, in Finland, the third child of healthy parents, was breast-fed and healthy. But by 2-weeks-old, he became irritable, started feeding poorly, and produced large volumes of watery feces with some blood. At 17-days-old he was taken to the Vaasa Central Hospital in Finland for medical care.

    A blood culture showed a gram-negative rod, which was identified as E. coli. Results of a test for the O157 antigen were negative. Because the neonate was severely ill, he was referred to the University Hospital in Pirkanmaa Hospital district, and the s E. coli train isolated from his blood was forwarded to the Helsinki University Hospital Laboratory, where the invasive strain from fecal specimens of the neonate and all 4 asymptomatic family members — the mother (31 years-old), father (32 years), sister (3 years), and brother (2 years) — was confirmed by detection of Stx. The 6 strains isolated from the blood and fecal samples of the neonate and from the fecal samples of his asymptomatic parents and 2 siblings showed a sorbitol-fermenting STEC serotype O78:H– that carried the virulence genes stx1 and hlyA.

    The boy recovered, but required a kidney transplantation, supplied by his father and performed in April 2011. The operation and posttransplantation period went without complications.

    HUS develops in ≈5%–15% of patients <10 years of age in whom E. coli O157:H7 infection is diagnosed and occurs 2–14 days after diarrhea onset. In contrast to the O157-related HUS cases, less information is available about the non–O157-related HUS cases. Some risk factors, including an elevated leukocyte count, administration of antimicrobial drugs, use of antimotility agents, and very young age, are associated with increased risk for HUS

    Ruminants, such as cattle and sheep, are the major reservoir of STEC. None of the family members, however, had contact with any farm animals, and the family had no pets. One of the family members of the neonate might have been infected with STEC by eating contaminated food, but these food items were not available for investigation. Moreover, because all the family members were asymptomatic, estimating the exact date of their infections is difficult. Secondary infections among family members most likely resulted from person-to-person transmission or from food given to the children with contaminated hands of other family members or from some other cross-contamination. Family clusters have been reported to be common. In Finland, ≈50% of STEC infections are family related.

    Handwashing practices may be of greater relevance than food as a source of infection in infants and very young children because the infection might result from an infected person or animal in the home. Prolonged excretion of STEC and intimate caring of infants by family members provide a risk for cross-infections. Therefore, to limit the risk for STEC infection, thorough handwashing before touching food or young babies is particularly necessary.

    Our findings demonstrate that contrary to earlier suggestions, STEC under certain conditions can invade the human bloodstream. Moreover, this study highlights the need to implement appropriate diagnostic methods for identifying the whole spectrum of STEC strains associated with HUS.

    I worry about this every time my daughter’s school brings in chicks and other animals. And I always make sure to ask if they are testing for salmonella and what kind of controls are in place. And I complain about parents parking in the handicapped spots. They think I’m crazy, but I’ll show them. Except no one wins with salmonella either.

    The U.S. Centers for Disease Control is reporting that salmonella infections from contact with live poultry (chickens, ducks, turkeys, and geese) continue to be a public health problem.

    In summer 2011, two clusters of human Salmonella infections were identified through PulseNet, a molecular subtyping network for foodborne disease surveillance. Standard outbreak and traceback investigations were conducted. From February 25 to October 10, 2011, a cluster of 68 cases caused by Salmonella serotype Altona and a cluster of 28 cases caused by Salmonella Johannesburg were identified in 24 states. Among persons infected, 32% of those with Salmonella Altona and 75% of those with Salmonella Johannesburg were aged ≤5 years. Forty-two of 57 (74%) Salmonella Altona patients and 17 of 24 (71%) of Salmonella Johannesburg patients had contact with live poultry in the week preceding illness. Most patients or their parents reported purchasing chicks or ducklings from multiple locations of an agricultural feed store chain that was supplied by a single mail-order hatchery. Live poultry were purchased for either backyard flocks or as pets.

    Live poultry are commonly purchased from agricultural feed stores or directly from mail-order hatcheries; approximately 50 million chicks are sold annually in the United States. Since 1990, approximately 35 outbreaks of human Salmonella infections linked to contact with live poultry from mail-order hatcheries have been reported. These outbreaks highlight the ongoing risk for human Salmonella infections associated with live poultry contact, especially for young children.

    In response to this ongoing public health problem, officials with local, state, and federal public and animal health agencies, the U.S. Department of Agriculture's National Poultry Improvement Plan (USDA-NPIP), the mail-order hatchery industry, and other partners have collaborated to develop and implement a comprehensive Salmonella control strategy. Mail-order hatcheries should comply with management and sanitation practices outlined in the USDA-NPIP Salmonellaguidelines and should avoid the shipment of hatched chicks between multiple hatcheries before shipping to customers. Educational materials warning customers of the risk for Salmonella infection from live poultry contact are available and should be distributed with all live poultry purchases.

    Over the past couple of days I've been hanging out traveling roadshow of North Carolina Cooperative Extension meetings where the focus is on strengthening communities through local foods. We're talking about stuff like research, production, processing, farm-to-school programs and community gardens and where extension folks are fitting in and leading. 

    One of the questions that has popped up at each of the sessions is whether local foods are safer than non-local foods and how that should be handled by extension. I answered that trying to compare safety (and for me that relates to microbiological risks) is kind of irrelevant and not supported by data- there are lots of food businesses from farm-to-fork that recognize, manage and control risks well -- and plenty that don't -- regardless of size and location.  A good food safety culture isn't linked to where the firm is geographically located - it's more likely influenced by whether they worry about making their customers sick. 

    This same local/centralized discussion is going on in Canada right now as the toque-wearing, Molson-swigging media takes notice of a recall of New Food Classics (now in receivership) beef products. The company was linked to an E. coli O157 illness in February and as CFIA digs into documented cleaning and sanitation practices and product distribution the recall has grown to include everything the company produced going back to July 2011. Instead of exploring New Food Classics food safety culture, the discussion is following a familiar big vs. little discussion.

    According to Toronto's NewsTalk1010:

    Food safety experts are debating the pros and cons of "centralized" beef processing versus local production after the Canadian Food Inspection Agency issued and expanded a widespread recall.

    Some experts say that while centralized processing is more cost effective than local production, it carries more risks. But other specialists disagree.

    "People mess up at all stages of production and people can do a really good job at all stages of production," says Ben Chapman, a Canadian food safety expert currently working in the U.S. Chapman says it's not about centralized versus local, but about the individual companies and their culture towards food safety.

    There are pros to local beef production according to food safety expert at the University of Toronto, William Navarre, "but in terms of food safety, I think the industrial model is actually the best one," Navarre says. Navarre says that it is easier to regulate, control and inspect larger companies.Another advantage in the centralized processing system,

    According to University of Guelph food science professor Keith Warriner, is the amount of money large processors are able to spend on safety. "The reality is that large processors have enough revenue, economies of scale, in order to implement food safety systems," Warriner says.

    The Ottawa Citizen reports that Ottawa's public health department has recorded a case of salmonella in a high school not served by the caterer believed to have been the source of the recent outbreak.

    The case at Merivale High School may be an instance where an older student caught salmonella from a younger sibling, said Eric Leclair, a spokesman for the health department.

    The tally of people who've contracted the foodborne illness since the department declared an outbreak remains at 50, though only 44 of them are believed to be connected via contaminated food delivered by a franchise of The Lunch Lady, a service that delivers hot food for children's lunches.

    The health department is still waiting for the results of lab tests on Lunch Lady food - meat used in lasagna and tacos, plus sour cream, cottage cheese and some spices - that would confirm the connection. Those are now expected by Friday, Leclair said.

    “There's an ick factor to almost all food."

    That was my short-take on the pink slime smearfest, which has now dragged retailers, along with the U.S. Department of Agriculture, into the murky morass where public opinion intersects with scientific evidence.

    This is nothing new.

    Me, I find E. coli and salmonella in raw sprouts icky.

    Other people find ammonium hydroxide, or pink slime, icky. People may soon discover they find citric acid icky because that’s what Cargill uses to yield finely textured beef and reduce the pathogen load.

    It’s pink, it’s meat, it’s lean finely textured beef – LFTB yo – versus pink slime in public opinion, and processors, retailers and government spokesthingies are acting like they’ve never encountered a food-related, or any risk-related issue where public opinion is different from scientific advice.

    It’s theatre, like a Mike Daisey production.

    Mike Hughlett of the Minneapolis Star Tribune writes today that Supervalu Inc., one of the nation's largest grocery chains, will no longer sell hamburger containing an ammonia-treated beef filler dubbed "pink slime" by some food critics and a growing chorus of consumers.

    The Eden Prairie-based company, which owns local supermarket leader Cub Foods, on Wednesday joined several fast-food chains and other major grocery operators in removing the controversial beef filler from hamburger sold in its outlets.

    "This decision was due to ongoing customer concerns about these products," said Mike Siemienas, a Supervalu spokesman.

    While ammonia-treated hamburger filler has gotten most of the popular attention, Supervalu also said its ban on so-called "finely textured beef" includes meat treated with citric acid, which is made by Minnetonka-based Cargill Inc.

    California-based Safeway Inc., another national grocery chain, also Wednesday said it nixed sales of both ammonia-treated and citric acid-treated ground beef fillers. Cargill spokesman Mike Martin acknowledged that some of its grocery industry customers have eliminated finely textured beef.

    "There have been customers who have contacted us because they have been contacted by consumers who are interested and concerned," Martin said.

    Did Safeway and Supervalu stores get eggs from those nasty DeCoster farms in Iowa that sickened some 2,000 people with salmonella in 2010. Did they rely on crappy food safety audits to make their decision. If they are so concerned about consumer concerns, why won’t they provide information on egg suppliers? Or any other food?

    Choice is a good thing. I’m all for restaurant inspection disclosure, providing information on genetically-engineered foods (we did it 12 years ago), knowing where food comes from and how it’s produced.

    But I want to choose safe food. Who defines safety or GE or any other snappy dinner-table slogan drop? Removing pink slime hamburgers reduces my choice to buy microbiologically safe food.

    USDA and the companies that previously outlawed pink slime acted expediently to manage a public-relations event. But they unwillingly undercut other efforts to provide safe, sustainable food.

    What is USDA going to do about school lunch purchases containing genetically-engineered ingredients, hormones, antibiotics, and a whole slew of politically-loaded ingredients or production practices?

    If consumers want to become food connoisseurs and safety experts, more power to them. I view my job, and the job of farmers, processors, distributors and retailers, regardless of political leanings, to make evidence-based information available and let people decide.

    Market microbial food safety and hold producers and processors – conventional, organic or otherwise – to a standard of honesty. Be honest with consumers and disclose what’s in any food; if restaurant inspection results can be displayed on a placard via a QR code read by smartphones when someone goes out for a meal, why not at the grocery store? Or the school lunch? For any food, link to websites detailing how the food was produced, processed and safely handled, or whatever becomes the next theatrical production – or be held hostage.

    Less than a year after trucks in Indiana were found to be transporting food at unsafe temperatures and raw vegetables soaked in meat drippings, a new state law will penalize truckers who transport food without complying with state health rules, beginning in July.

    Tom Karst of The Packer reports that the law means trucks transporting perishable foods without proper refrigeration can be inspected, detained and in certain cases, impounded by law enforcement officers.

    The law would expand police powers, giving state police the authority to confiscate equipment and loads, said Joe Rajkovacz, regulatory affairs specialist with the Grain Valley, Mo.-based Owner-Operator Independent Drivers Association.

    During an investigation in 2011, Rajkovacz said distributors from Chicago who were supply food to ethnic markets and restaurants were flagged as transporting unrefrigerated loads of perishable food. He said police never found the same issues with long-haul trucks coming out of California.

    The law states a person may not operate a motor vehicle for the transportation of food upon a public highway unless the vehicle complies with state rules regarding transportation of food.

    An officer may inspect vehicles use to transport food to determine if the vehicle complies with state health rules.

    If an officer finds that the temperature of the food is more than two degrees above the acceptable temperature, or if the food exhibits outward signs of contamination, of if the food is improperly loaded so as to risk cross-contamination, the law authorizes the officer detain the vehicle and to contact a health inspector to conduct an investigation. The law also states that a health inspector may order the disposal of certain food and the impoundment of noncomplying motor vehicles.

    Barb Hunt, vice president of the Indiana Motor Truck Association, Indianapolis, Ind., said the legislation found overwhelming support in the legislature following the media reports about hot trucks last summer.
