E.coli levels in the drinking water supply for the city of Aberdeen, SD have reached dangerous levels, prompting city officials to issue a boil water advisory.
Aberdeen residents should not drink tap water without boiling it first. Before it is safe to drink, the water needs to boil for a full minute. “Boiled or bottled water should be used for drinking, making ice, brushing teeth, washing dishes, and food preparation until further notice,” the advisory states
The aim of this research was to determine the decimal reduction times of bacteria present on chicken fillet in boiling water. The experiments were conducted with Campylobacter jejuni, Salmonella, and Escherichia coli. Whole chicken breast fillets were inoculated with the pathogens, stored overnight (4∘C), and subsequently cooked. The surface temperature reached 70∘C within 30 sec and 85∘C within one minute. Extremely high decimal reduction times of 1.90, 1.97, and 2.20 min were obtained for C. jejuni, E. coli, and S. typhimurium, respectively. Chicken meat and refrigerated storage before cooking enlarged the heat resistance of the food borne pathogens. Additionally, a high challenge temperature or fast heating rate contributed to the level of heat resistance. The data were used to assess the probability of illness (campylobacteriosis) due to consumption of chicken fillet as a function of cooking time. The data revealed that cooking time may be far more critical than previously assumed.

County environmental health officials have ordered the closing of a popular Walnut Creek pizza restaurant after test results confirmed that customers and restaurant staff have norovirus.
Contra Costa County Environmental Health Director Marilyn Underwood said the county ordered California Pizza Kitchen at Broadway Plaza, Walnut Creek, closed at 5 p.m. Thursday after receiving lab resulting confirming norovirus.
Norovirus is a contagious virus that you can get from an infected person, contaminated food or by touching contaminated surfaces. Each year, norovirus causes about 21 million gastrointestinal illnesses, and contributes to about 70,000 hospitalisations and 800 deaths, according to the website of the federal Centers for Disease Control and Prevention.
County officials have linked the norovirus to a food-borne illness outbreak connected with salad served Thursday, June 7, at the California Pizza Kitchen at Broadway Plaza, Walnut Creek.
County officials went to the restaurant Thursday evening and posted a notice closing the restaurant under the authority of state law. They asked the staff to close the restaurant. The staff quietly asked customers to leave, Underwood said.
The first batch of samples came back Thursday. Of five employees tested, three positive for norovirus, Underwood said. Of two customers tested, both were positive for norovirus.
Japan has announced that it will ban the sale of raw beef liver in restaurants, following a spate of food poisoning cases last year.
The health ministry has decided to ban restaurants from serving raw beef liver from July 1 due to food poisoning concerns, and violators of the new rule could be fined or even imprisoned.
The ministry made the decision after its food sanitation council approved the policy at a meeting Tuesday.
Enterohemorrhagic E. coli O-157 and Campylobacter bacteria, both of which can cause severe stomachache, have been detected in raw beef liver. A research report said it is difficult to remove or kill the bacteria through screening tests or disinfection, and that liver can only be guaranteed safe to consume if it has been cooked.
Operators of barbecue restaurants and other establishments that ignore the ban on raw beef liver could be sentenced to up to two years in prison or fined up to 2 million yen.
At Tuesday’s meeting, the Health, Labor and Welfare Ministry presented comments submitted by the public over the month through May 18. Although most of the 1,532 opinions were against outlawing raw liver, ministry officials insisted a ban–backed up by penalties–was necessary because there is no 100 percent safe way of eating raw beef liver.
12 June 2012: Food Standards Australia and New Zealand has issued a notice on the recall of some batches of Casa brand’s Marinated Feta in Australia due to a risk of microbial (E.coli) contamination.
There is no import of the retail pack of the affected products in Singapore. While there is an import of the 1.5kg trade pack of the affected product, the consignment has not been distributed for sale and will be destroyed.
Consumers who have bought the implicated products overseas should discard the products and not consume them.

New York State Agriculture Commissioner Darrel J. Aubertine today warned consumers in and around Chautauqua County to not consume “unpasteurised” raw farm milk from Castle Farms due to possible E. coli O157:H7 contamination.
Castle Farms, located at 1051 Route 249 in Irving, New York, holds a Department permit to legally sell raw milk at the farm. Samples of the milk are routinely tested by the New York State Food Laboratory to determine if the raw milk is free of pathogenic bacteria.
It is important to note that raw milk does not provide the protection of pasteurization, which eliminates all pathogenic bacteria, including E. coli O157:H7. Producers who sell raw milk to consumers must have a permit to do so from the Department, must sell directly to consumers on the farm where the milk is produced and must post a notice at the point of sale indicating that raw milk does not provide the protection of pasteurization. Farms with permits to sell raw milk are inspected by the Department monthly.
To date, no illnesses are known by the Department to be associated with product from Castle Farms.
Golden Glen Creamery of Bow, WA, in cooperation with the WSDA is voluntarily recalling Red Pepper with Onion & Garlic Cheddar produced on August 30, 2011 because it has the potential to be contaminated with Listeria monocytogenes. The Creamery agreed to recall the product after a sample taken by the WSDA returned with a positive result. Samples of the same batch have tested negative through an independent, state-approved lab that Creamery has submitted samples to. No illnesses have been reported to date. L. monocytogenesis an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.
To date, no illnesses have been reported.
