It matters what’s done after people barf. Same if people have diarrhea – in a pool.

During the summer of 2007, almost 6,000 people in Utah started barfing from Cryptosporidium, transmitted via the barfblog fav, fecal-oral route

The U.S. Centers for Disease Control reports that of 1,506 interviewed patients with laboratory-confirmed cryptosporidiosis, 1,209 (80%) reported swimming in at least one of approximately 450 recreational water venues during their potential 14-day incubation period.

Cryptosporidium is extremely chlorine-tolerant, and secondary or supplemental disinfection with ultraviolet light or ozone can control but not prevent outbreaks. Because swimmers are the primary source of Cryptosporidium contamination, healthy swimming campaigns are needed to increase awareness and practice of healthy swimming behaviors, especially not swimming while ill with diarrhea (i.e., swimming while ill with diarrhea can lead to gross contamination of recreational water). Before the 2008 summer swimming season, Utah public health agencies launched a multimedia healthy swimming campaign. To assess knowledge of healthy swimming, a survey of Utah residents was conducted during July–September 2008. The results of that survey found that 96.1% of respondents correctly indicated that "it is not OK to swim if you have diarrhea."

In a separate national survey in 2009, 100% of Utah residents but only 78.4% of residents of other states correctly indicated that "not swimming while ill with diarrhea protects others from recreational water illnesses (RWIs)." No recreational water–associated outbreaks were detected in Utah during 2008–2011. The healthy swimming campaign, as part of a multipronged prevention effort, might have helped prevent recreational water–associated outbreaks of cryptosporidiosis in Utah.

Before the 2008 summer swimming season, Utah's state and local public health agencies teamed with community partners to control recreational water–associated transmission of Cryptosporidium. For example, the Salt Lake Valley Health Department (SLVHD) collaborated with pool operators to establish fecal incident–response protocols and install secondary or supplement disinfection systems to inactivate Cryptosporidium at 75 treated recreational water venues.

SLVHD also collaborated with the Utah Department of Health and diagnostic laboratories to expedite reporting of cryptosporidiosis cases to public health authorities. To engage the public in prevention, SLVHD led efforts to disseminate healthy swimming messages via a website, two television advertisements, public service radio announcements, and posters at pools (e.g., "A Swimming Pool is Like a Community Bathtub"). In addition, targeted messages were disseminated to schools, competitive water sports teams, and licensed childcare facilities. SLVHD also conducted a press conference during Recreational Water Illness and Injury Prevention Week, which is held each year the week before the Memorial Day holiday.

At least 150 people who attended a Mother's Day garden party at an upstate New York Buddhist monastery have fallen ill with food poisoning.

Eric Gross, spokesman for the Putnam County Bureau of Emergency Services, says about 700 people were at the festival at Chuang Yen Monastery in Kent Cliffs, 55 miles north of New York City. About 500 of them came on buses from Chinatown.

Gross says people starting getting sick with vomiting and diarrhea around 3:30 p.m. Sunday after they had left the party on buses bound for Woodbury Commons shopping outlets. As of 7 p.m., Gross said 150 had been taken to hospitals in Putnam, Orange and Westchester counties.

Officials urged people who attended the party and feel ill to call the Putnam County Health Department: 845-808-1390.

Public health officials are investigating several cases of stomach illnesses in sixth formers at a Cardiff school.

There has been one confirmed case of cryptospiriodis amongst sixth formers at The Bishop of Llandaf Church in Wales school.

Four other cases are also being looked at amongst pupils who went on a school trip over the Easter holidays.

Perhaps they went to a farm?

When catering a meal for health professionals, it may be important to get food safety basics right.

The Pueblo City-County Health Department in Colorado has temporarily closed All Seasons Catering, citing a variety of violations found after more than 30 people were sickened by food the company served at a luncheon last week.

The health department found evidence of Clostridium perfringens toxin in a beef-and-gravy dish, butter, tomatoes and lettuce the caterer served during last Tuesday's Pueblo Community Health Center annual meeting and luncheon.

An inspection following the barfing found:

• Critical Lack of demonstration of knowledge by PIC. Kitchen manager admitted to not taking final cook temperatures, and holding temperatures of all food, did not know cooking temperature of poultry should be 165 degrees.

• Critical Employees not handwashing when required. Observed employees changing tasks, changing gloves, handling ready to eat foods without washing hands

• Critical Observed employee "trying" to check temperature of pasta with bare hands, not using a thermometer.

• Critical Improper cooling time/temperature specified time parameters not met. three pans of cooked vegetables made 4/25/12, holding in walk-in refrigerator at 67-72 degrees, did not meet proper cooling parameters.
