    The Public Health Agency of Canada, which was created to streamline various public health duties like providing meaningful data on foodborne illness and provide leadership on public health issues (totally useless during the 2008 listeria in deli meats outbreak that killed 22) has gotten around to releasing so-called integrated surveillance data for selected enteric diseases in Canada.

    This report focuses on the years 2000 to 2004. The pathogens described are Salmonella, Campylobacter, verotoxigenic Escherichia coli and Shigella. From 2000 to 2004, a general decline in reported rates of all four pathogens was observed in all except a few provinces. When looking at more long-term trends from 1995 to 2004, a similar decline was seen in nationally reported rates for all four pathogens. S. Typhimurium was the most frequently reported Salmonella serovar during the five-year period described, followed by S. Heidelberg and S. Enteritidis. C. jejuni remained the most prevalent Campylobacter species reported between 2000 and 2004. E. coli O157 comprised the majority of verotoxigenic E.coli isolates over these five years. Shigella sonnei was the most frequently reported Shigella species.

    Hospitalizations, deaths, outbreaks and case clusters, as well as unusual isolation sites and travel-acquired infections are also explored in this report. Pathogenic E. coli was associated with the highest hospitalization rates over the five-year period, although Salmonella infections resulted in the largest number of deaths overall. Data on outbreaks and case clusters is limited to those reported to the National Enteric Surveillance Program (NESP) and the National Microbiology Laboratory (NML).


    Which means, not much. The data is exceedingly limited, and why it took at least 5 years to report is baffling. Canadians can comfortably go back to sleep.

    There aren’t enough castles with moats.

    At least not anymore.

    But Cardiff Castle in Wales, which dates back to 3rd century Romans, has a lovely moat constructed by the Normans to fend off the locals as they pillaged their way across what is now the U.K.

    The food has been uneventful, all of it served piping hot as the Brits suffer through their worst snow and cold in 30 years. To watch the constant news and weather reports on BBC 1, BBC 2, BBC 4, and Sky News – there is one movie channel that seems to feature bad 1980s American fare – and read the newspaper accounts, the country is in chaos and everything has been shut for at least two days.

    We drove from Cardiff to Manchester when people were told to stay off the roads and it was completely uneventful, what with the couple of inches of snow. Guess they aren’t used to that around here.

    Some attempted to escape the weather, only to end up barfing.

    USA Today today reports that Britain's Fred Olsen Cruise Lines has ordered an early end to a cruise to the Canary Islands after a massive outbreak of what is believed to be norovirus.

    The UK's Daily Mail reports at least 289 of 795 passengers on Fred Olsen's Boudicca this week have been struck down by the illness. At 36% of passengers, it's one of the most widespread outbreaks of a norovirus-like illness recorded on a cruise ship in years. Even the worst outbreaks of norovirus rarely spread beyond 10% of passengers.

    The outbreak, moreover, is the third in a row for the ship and comes as another Fred Olsen vessel, the Balmoral, also struggles with a major outbreak of norovirus-like illness -- it's third in a year.

     The aptly named Campaign for Responsible Rodenticide Use (CRRU) reports that a survey of British farmers and countryside managers found 61% of respondents noticed a rising rat population already and 74% believed that climate change would exacerbate the problem.

    The survey is corroborated by the National Pest Technicians Association (NPTA), which found a 15% year-on-year increase in treatments in local authorities for rat infestations.

    CRRU chairman, Dr Alan Buckle, said the UK rural rat population consumes an estimated 200t of food a day that would otherwise be destined for humans. One in every two farm fires, he adds, is believed to be started by rat damage causing electricity cables to short.

    Even in Kansas, rats have twice sought shelter in our parked car’s engine and gnawed through the ignition wires.

    And if those rats are frolicking and fornicating in the country, their numbers will only get worse in the city.

    According to the CRRU:

    • One rat produces about 40 faecal pellets and 15ml of urine each day, or 14,600 and five litres respectively per year.

    • Salmonella, leptospira, toxoplasma, listeria, campylobacter and cryptosporidium are some of the highly pathogenic organisms carried by rats.

    The U.S. Centers for Disease Control and Prevention issued a summary report today on a Multistate Outbreak of Human Salmonella Typhimurium Infections Associated with Aquatic Frogs --- United States, 2009.

    During April--July 2009, the Utah Department of Health identified five cases of Salmonella Typhimurium infection with indistinguishable pulsed-field gel electrophoresis (PFGE) patterns, predominantly among children. In August, CDC began a multistate outbreak investigation to determine the source of the infections. This report summarizes the results of this ongoing investigation, which, as of December 30, had identified 85 S. Typhimurium human isolates with the outbreak strain from 31 states. In a multistate case-control study, exposure to frogs was found to be significantly associated with illness (63% of cases versus 3% of controls; matched odds ratio [mOR] = 24.4). Among 14 case-patients who knew the type of frog, all had exposure to an exclusively aquatic frog species, the African dwarf frog. Environmental samples from aquariums containing aquatic frogs in four homes of case-patients yielded S. Typhimurium isolates matching the outbreak strain. Preliminary traceback information has indicated these frogs likely came from the same breeder in California. Reptiles (e.g., turtles) and amphibians (e.g., frogs) have long been recognized as Salmonella carriers (1,2), and three multistate outbreaks of human Salmonella infections associated with turtle contact have occurred since 2006 (3,4). However, this is the first reported multistate outbreak of Salmonella infections associated with amphibians. Educational materials aimed at preventing salmonellosis from contact with reptiles should be expanded to include amphibians, such as aquatic frogs.

    It has been years since my Subway sandwich artist days, but I think I could still make a delicious sub if put behind the counter. I worked there for over three years, during which time I noticed a few odd things. One thing was the roast beef. There was always some green gasoline-like sheen on the slices of deli meat (see right). Whenever I had to make a sub that had roast beef I’d get nervous and concerned the customer would ask what it was – I had no idea – until today.

    When reading a story in the Sun Chronicle Online about a Massachusetts Subway’s green roast beef, the memories came back to me and I decided to do some investigating.

    A co-worker who worked in a meat laboratory explained to me, and this University of Saskatchewan paper on meat colour agrees, that the odd colour I was seeing was likely due to light reflections on sliced meat muscle fibers (which is not a food safety issue).

    From the paper,

    Iridescence is a common problem in sliced roast beef and ham products. The dominant color is frequently green and consumers sometimes confuse this with green myoglobin pigments associated with microbial growth. The iridescence of meat products is produced by a combination of the angle of incidence of the light on the muscle fibres and the wetness of the surface. If the fibres are pulled slightly out of alignment during slicing, the light strikes the fibre at an angle scattering light which
    appears as the rainbow or greenish color on the surface of the meat. 

    Whether or not this explains the green on the Massechusetts Subway’s roast beef, I do not know, but does answer a question I forgot I had.

    Reports from the ABC affiliate in Newark (NJ) are that Iberia, a popular local restaurant, is the source of an outbreak linked to Salmonella. To date there have been 35 illnesses reported with five culture-confirmed as Salmonella. All illnesses appear to be linked to Christmas parties on 5 different dates.  While many dishes are being investigated, 7 different homemade sauces have been sent to state laboratories for testing. All restaurant staff have also been tested.

    Ramona Serra, one of the reported victims (but with some symptoms not too consistent with salmonellosis) was quoted as saying:

    "We had a Christmas party there, and I got a headache around 10:30 and I didn't feel good the next day." Serra is among 13 people who got sick at their company Christmas party at the Iberia Peninsula Restaurant at 63 Ferry Street in Newark. Three of them were hospitalized.
    "They had a stomach pains, belly ache pains, their whole body was aching them," Serra said. "They were really bad."

    Isolated, that's what Iberia general manager George Loueira said about the outbreak, "This is an isolated incident. It's under investigation. We want to have everybody continue to patronize the business." I bet. An outbreak isn't the best advertisement and 5 different dates doesn't sound too isolated.

    Since the investigation started on Dec. 28/09 the Newark Department of Health has placed an inspector in the kitchen to monitor food handling and handwashing.

    Initially reported as an outbreak of foodborne illness among 30 patrons, WRAL reports tonight that up to 280 people have reported becoming ill after eating at Raleigh's 42 St. Oyster Bar in late December. Health authorities also believe that illnesses also might not have been linked to oysters as initially reported. As Norovirus is easily transmissible and needs only a few particles to infect, it will be difficult for investigators to pinpoint the initial source. Health authorities tested eight employees for norovirus and all have been negative for the virus.

    42nd Street owner Brad Hurley initially thought the culprit was oysters from Louisiana. As a precaution, the restaurant immediately stopped serving the Louisiana oysters and started using only oysters from North Carolina.

    Tests of the remaining Louisiana oysters have come back negative, Andre Pierce, Wake County's environmental health and safety director said.

    The restaurant has also worked with the health department to take other precautions, such as eliminating bare hand contact with food and changing from an ammonia sanitizer to chlorine.

    Pierce said they may never know the exact source.

    "Norovirus is probably one of the most unreported food illnesses out there. It's hard to detect. It's hard to find a source. We spend a lot of time and resources trying to track it down. And it is frustrating to us and it is frustrating to the public that you can't just put a finger on it, but it is very present and I think it's a lot more out there than we realize."

    Public vomiting is particularly a problem as the act of spewing can cause particles to spread. Norovirus particles can also stay viable on surfaces for weeks. Pathogens can be passed on by someone even if they aren’t feeling ill. In 2008 a foodhandler who did not show symptoms or test positive for Norovirus caused an outbreak leading to over 30 illnesses. It's believed that the foodhandler, who was caring for ill family members at home, introduced the norovirus into the kitchen by practicing poor personal hygiene.

    Maybe it’s the weather. The U.K. is in the midst of its biggest snowstorm in 40 years but at least it’s not -10F, like it’s going to be in Kansas this week.

    Whatever the reason, Kansas City police want to know the identity of a woman who trashed a McDonald’s restaurant Dec. 27 because she hated her hamburger.

    According to police, when the woman complained about her hamburger, employees offered to replace it. She demanded her money back. Employees declined.

    So the woman threw a glass water dispenser over the counter, breaking it. She pushed three cash registers off the counter, smashing one touch screen. She cursed and fled.  The video is below.

    In Toledo, Ohio, police say a woman punched through a McDonald's drive-through window, taking swipes at a couple of employees, because Chicken McNuggets weren't available -- at 6:20 a.m.. Police say 24-year-old Melodi Dushane was treated for injuries, and jailed.

    USA Today today says the U.S. Centers for Disease Control in Atlanta recorded just 13 outbreaks of gastrointestinal illness on cruise ships in 2009, down from 15 in 2008, 21 in 2007 and 34 in 2006.

    The decline, moreover, came even as the number of people cruising continued to rise. The Cruise Lines International Association says the industry carried 13.2 million passengers in 2008, the last year for which data is available, up from 12.6 million in 2007 and 12.0 million in 2006.

    Cruise ships arriving in U.S. ports must report all cases of gastrointestinal illness treated by on-board medical staff to the CDC's Vessel Sanitation Program division, and a separate notification is required when the number of cases exceeds 2% of passengers and crew. When the number of cases exceeds 3% of passengers and crew the CDC issues a public report.

    It might look good today, but by cleaning up is the Aramark-managed Capitol cafeteria the "safest restaurant in the city of Harrisburg"?

    PennLive.com reports that after being closed by Pennsylvania officials on December 17th following an inspection that revealed rodent droppings, underheated dishwashing water and poor food handling procedures, Capitol is trying to clean up their image. Bruce Walton, vice president for operations of Aramark was cited as saying that prior to the closing, more than 1,500 customers ate at the Capitol cafeteria on busy weekdays and that rebuilding that steady clientele will take time.

    After a thorough clean-up, a new pest control program with Ecolab and contracting with a company to provide surprise audits, Aramark district manager Andre Obendorfer was quoted as saying "This is the safest restaurant to eat in in the city of Harrisburg."

    Ah, the safest food/safest restaurant comment; impossible to back-up with evidence and leaves everyone who eats there with a warm and fuzzy feeling.

    Walton, by not disclosing any firings or discipline, downplayed what might be the most important change -- personnel. He was quoted as saying that they "did make changes in our team." Rodent control and a cold dishwasher can lead to public health issues, but other violations found on December 17th including indirect cross-contamination (handling potentially contaminated equipment and then going to clean equipment, possibly leaving pathogens for the next person) and not having paper towels, demonstrate a lack of a food safety culture. A personnel and management issue.

    Food safety culture is a set of values wherein food safety risks are openly identified, discussed, and addressed. What this means is that anyone who works there -- from manager to dishwasher -- knows that paper towels can reduce risks so they refill the dispenser. Food safety is supported from the organization but it's the front-line folks who hold the health of patrons in their hands. An organization like Aramark needs to be building the food safety culture capacity behind the scenes, not just touting how clean everything looks now.

    To assure patrons of their commitment to food safety, the article reports that Aramark will have staff on site to answer questions, use guest chefs and in the most bizarre step, revamp cafeteria stations such as turning the pizza station into an "Italian zone." I guess visitors to the Capitol Complex have the perception that Italian food is safer than pizza?

    At the Dallas airport on Jan. 1, 2010, Amy ordered a hamburger while awaiting our flight to London’s Heathrow airport.

    “How would you like that done?”

    “160F please”

    “Does that mean medium-well?”

    Sigh.

    We booked an airport hotel for one night to recover from the trip – and to learn to drive on the wrong side of the road, with a stickshift on the wrong side of the steering wheel, and negotiate the many, many roundabouts.

    We ate dinner in the hotel bar where the only thing on the tele seemed to be … darts.

    Next it was off to Oxford where we spent a quite lovely day and night with a colleague of Amy’s and her husband (above, right). Dinner was baked wild haddock with parsnips, carrots and other roasted veggies.

    Today, we travelled to Newport, Wales, where many of the Powell’s hail from, including my father, grandfather, and others. We visited with a spry 80-year-old Keith Powell (below, left), a son of my grandfather’s brother, and dined at a carvery – a pub offering British fare of turkey, ham or beef carved from an intact bird or roast and served with unlimited roast veggies and other sides. While the food safety possibilities exist with carveries, this one was well-maintained and under the watchful eye of the carverer. Sorenne must have been starving as she gobbled up turkey, and when I refused a bowl for fear Sorenne would throw it at Keith or elsewhere, he asked as I put the meat directly on the high-chair table, “Are you sure that thing’s clean?”

    Must run in the family. When I returned the table-top, the first thing a server did was wipe it down with a cloth soaked in sanitary solution.

    Tomorrow, Cardiff.

    The Toronto Sun reports that 28-year-old Tommy Lam and his girlfriend stopped by the McDonald’s at Markham Rd. and Denison St., north of Toronto, around 11 a.m. last week to order four pita-wrapped sausage and egg burritos to eat on their way to work.

    Soon after, they sat down to eat at his business, Jewellery Box, just around the corner at Steeles Ave. E. and Middlefield Rd., Lam claims they spotted dozens of ants inside and outside their burritos.

    Fortunately, the little critters weren't crawling around. But that was of little consolation to Lam, who had already eaten the first of his two burritos.

    Whether or not that first sandwich was also laced with dead ants, Lam is not sure.

    When Lam returned to the store, Lam said the McDonald's manager, "didn't even offer an apology. … He offered to replace our burritos, that was it. I just said, 'No thanks!' and walked out."

    Lam said he later tried to contact McDonald's head offices and his local public health department, but he wasn't able to reach anyone over the long weekend.

    I’m still not sure of the difference between insanitary and unsanitary, like insane and unsane, but the dictionary says insanitary means, “so dirty or ridden with germs as to be a danger to health,” whereas sanitary is defined as, “of or relating to the conditions that affect hygiene and health,” and the word unsanitary does not exist.

    Perhaps a linguist can settle this. In the meantime …

    The U.S. Food and Drug Administration today announced intentions to ask a federal court to shut down a New Jersey cheese manufacturer with an alleged history of operating under insanitary conditions and producing cheese contaminated with Listeria monocytogenes.

    The U.S. Department of Justice filed a complaint for permanent injunction against Quesos Mi Pueblito and two of its officers, Felix Sanchez and Jesus Galvez. The complaint alleges that recent inspections by the FDA and the New Jersey Department of Health and Senior Services found Listeria-contaminated cheese and insanitary conditions at the Passaic company.

    If entered by the court, the injunction would stop the company and its officers from manufacturing and distributing food until they can bring their operations into full compliance with FDA food safety regulations and produce cheese that does not test positive for the presence of Listeria. The complaint for permanent injunction was filed in the U.S. District Court - District of New Jersey.

    The Toronto Globe and Mail used to be a decent newspaper. I was enamored with the paper and its journalists as a genetics undergrad, was thrilled when I started writing regularly for the paper in the 1990s, and then dismayed as the amount of crap published began to far outweigh the thoughtful stuf.

    Once such sign of decline was the hiring of columnist Leah McLaren about a decade ago. Chapman was somewhat enamored with her self-indulgent depictions of young female life in hip Toronto; I thought it was bullshit.

    Leah is still at the Globe as it continues its drawn-out decline, and wrote on Saturday that,

    “This year for Christmas I poisoned the in-laws.

    “They had flown all the way from Toronto to spend the holidays in London, dragging several extra bags of gifts across the Atlantic like a modern-day Santa and Mrs. Claus. In return, I had planned a feast for dinner.

    "The centrepiece of the meal was a beautifully aged prime rib roast. I had purchased it, for nearly $100, from my local Notting Hill butcher, who specializes in organic, free-range, ethically farmed beef, lamb and poultry.

    "I don't eat much meat these days, but everything about that shop made me feel safe, from the quaint striped awning to the well-heeled locals queuing up for their premium giblets to the butcher with his starched, white-linen apron making small talk as he trimmed the leg of lamb. Even the store's slogan ("Real meat naturally fed") was heartening. What could possibly be more healthy, comforting or downright trendy than a rib roast for Christmas? As I stepped out of the shop with my several pounds of Grade A flesh in hand, I was determined to follow the butcher's emphatic instructions: "Do not overcook."

    "And I didn't. The prime rib was perfect - except for the 36 hours of stomach-churning misery it caused everyone who ate it."


    Leah’s lesson from all this? Don’t eat red meat.

    One Moses Shuldiner responded with a letter in the Globe today, stating that Leah’s “mistake was to not inform herself of proper food handling techniques as recommended by the Toronto Public Health Department, which can be downloaded from the City of Toronto's website. … After reading information from public health anyone can, for a nominal fee, write the test to become a certified food handler, ensuring mastery of the material.”

    Shill. Mere mortals do not have to become certified food handlers to cook dinner for the in-laws, or anyone else. I cooked lamb on Christmas Eve and my 1-year-old ate it. No one barfed. Use a tip-sensitive digital meat thermometer. Next time, Leah, stick it in.

    The Las Cruces Sun-News reports that a rule change will go into effect today that requires those who sell home-based food products to have a permit issued by the New Mexico Environment Department.

    That permit will allow the sale of certain foods that can be prepared in home-based food processing operations within state jurisdiction. Those foods include yeast and quick breads, cookies, cakes, tortillas, high-sugar pies and pastries, high-sugar jam and jellies, dry mixes (made from commercial ingredients), candy and fudge. Those foods do not support the rapid and progressive growth of infectious and toxicogenic microorganisms, including Clostridium botulinium, responsible for foodborne disease.

    The food permit costs $100 a year. To obtain a permit to operate, a seller can submit an application to a local NMED field office. The application package is available at www.nmenv.state.nm.us/fod/Food_Program or at your local NMED field office.


    As Ben and Brae wrote in the Wisconsin State Journal back in March, 2006, leave the umpires in the field -- the health inspectors who make sure everybody plays by the rules. In this game we need to get along so it doesn't leave a nasty and sometimes lethal taste in the mouths of players or spectators.
