Australia – Tasmanian Scallops PSP and Unsafe Poultry

AFNSalmonella Campylobacter

The Food Safety Information Council has released concerning national survey data this week that shows 60% of home cooks in Australia are putting themselves at additional risk of food poisoning from chicken.

The data showed that 60 per cent were at risk from washing whole poultry before it was cooked, which can spread bacteria around the kitchen. A further 16% of those surveyed incorrectly tasted chicken to see if it was cooked properly rather than using a safe meat thermometer.

The focus on cross-contamination of meats by the Food Safety Information Council (FSIC) comes as yesterday marked the start of Australian Food Safety Week. The FSIC week is specifically focusing on chicken and those most affected by food poisoning with the theme “vulnerable populations.”

Food Safety Information Council Chairman, Dr Michael Eyles said that chicken, as Australia’s most popular meat, was consumed by 8 in every ten home cooks.

”Home cooks are probably following what their parents or grandparents did in the past by washing poultry, not to mention probably patting it dry with a tea towel. Washing poultry splashes these bacteria around the kitchen cross contaminating sinks, taps, your hands, utensils, chopping boards and foods that aren’t going to be cooked like salads or desserts,” Dr Eyles said.

“Chicken is a healthy, convenient meal [but] other poultry is also becoming popular with just under half of those surveyed cooking whole turkey and 37% whole duck but these, too, are being washed before cooking, with 68% washing turkey and 74% duck,” he added.

According to a Food Standards Australia New Zealand survey referenced by the Food Safety Information Council, 84 per cent of raw chicken carcasses tested positive to the food poisoning bacteria Campylobacter and 22 per cent to Salmonella.

SCALLOPS from the east coast of Tasmania have joined the area’s mussels in being banned following a toxic algal bloom.

A scallop fishery in the White Rock area has been closed after the same paralytic shellfish toxin (PST) found in Spring Bay Seafood’s mussels was detected in samples taken on November 2.

“PST levels in tested scallops are currently either close to or slightly over the permitted level, but it’s possible the level will increase before it goes back down again,” a health department warning said.

The affected shellfish don’t look or taste different and the toxin is not destroyed by cooking or freezing, but there have been no reports of illness.

USA – Sunland Peanut Butter – FDA Suggestions the Company Knew About the Salmonella

Huff Post

The food world is still reeling from the salmonella outbreak that sickened at least 41 people across 20 states, which was linked to Sunland peanuts that were sold as peanut butter at Trader Joe’s and several other supermarket chains. Now, information released late last month by the FDA suggests that Sunland knowingly sold potentially contaminated products going back to 2009 [pdf].

UK – Restaurant Implicated in Campylobacter Cases

The Telegraph

Two customers at Blanc Brasserie, in Covent Garden, London, were left ill after eating pink lamb’s liver which was not cooked thoroughly enough, a court has been told. The restaurant has now been banned from serving the dish, after failing to heed a warning from council environmental health officers, Westminster Magistrates’ Court heard. The food had “presented an imminent risk of injury to health because the process of cooking”, the court was told. Blanc Brasseries will now pay £3,103 in costs and have confirmed they will comply with the order, as a spokeswoman said they were unable to cook the liver to council standards without compromising on taste.

“Brasserie Bar Co has not contested the EHO enforcement and will no longer serve liver in any of its restaurants,” she said.

Armenia – Clostridium botulinum Incidents 2012

NEWSAM 

Total of 11 cases of botulism were registered during the 11 months of this year with 17 poisoned people out of which two ended fatally, Sanitary-Epidemiological Service at the Armenian Healthcare Ministry informed Armenian News Am. Two of the poisoned persons were children. The poisoning cases were registered in Yerevan, as well as in Shirak, Ararat, Armavir, Lori and Tavush regions of Armenia. As a matter of fact, 19 cases of botulism were registered last year with 30 poisoned people, 3 of whom died.

To avoid the poisoning, the Ministry warns again not to prepare canned food at home, or at least to boil it for up to 30 minutes before consumption.

USA – Recall – Cheeses – Listeria monocytogenes

Kennys Farmhouse Cheese

Kenny’s Farmhouse Cheese (KFHC), due to the abundance of caution, is conducting a voluntary recall due to routine testing based on our company’s concern for our customers. This testing confirmed the presence of Listeria monocytogenes in a few samples of the following cheeses. At this time, no illnesses have been reported, but to ensure that all suspect product is removed from the marketplace, KFHC is initiating this voluntary recall in cooperation with the Milk Safety Branch of the Kentucky Department

of Health Services (KDHS) and the US Food & Drug Administration (FDA).

USA – Shellfish Vibrio Poisoning

Food Poisoning Bulletin Vibrio

The Cape Cod Times is reporting that eight cases of Vibrio food poisoning were reported in Massachusetts this year from oysters. Last summer the state designed new regulations to keep consumers safe from this bacteria, but they failed.  The eight cases were linked to oysters harvested from Wellfleet, Orleans, Edgartown, Duxbury, Kingston, Barnstable, and Dennis.

Vibrio populations double every 15 minutes, so keeping shellfish cool is critical to controlling bacterial growth.  

Vibrio was not seen in Massachusetts oysters until 2011 because the state’s colder water temperatures discouraged the growth of the bacteria. In every month in 2012, the mean air temperatures were higher than average, including the third-warmest April and the warmest August on record. Sea surface temperatures this year were the highest ever in the Northest.

Research – Norovirus and Cleaning

HACCPEUORPA

Noroviruses are a group of viruses that are the most common cause of gastroenteritis (stomach bugs). They are very contagious and can spread easily from person to person. People exposed to the virus usually develop symptoms of illness within 24 to 48 hours, but symptoms can occur as early as 12 hours after exposure.

Common-sense based disinfection guidelines to control norovirus contamination have been developed, but now, for the first time, a Dutch team has come up with science-based guidelines.

In the study the researchers first determined how low the concentration of virions needed to go for transmission to become unlikely. They then tested different methods of cleaning hard surfaces, by using water, soap, or chlorine bleach solutions to determine the best method, or combination of methods for achieving a sufficiently low concentration to prevent virus transmission from hard surfaces, such as your kitchen counters.

The researchers prescribe a two-step process: wipe with a wet cloth, and then disinfect with chlorine. Their prescription is directed at hospitals, schools, restaurants, and other food-handling establishments. In most cases, a 250 ppm solution of chlorine is sufficient, but for high levels of contamination, they recommend 1,000 ppm. To achieve 1,000 ppm, one Suma Tab D4 tablet must be dissolved in 1.5 liters of water (about a quart and a half).

Norovirus is no more resistant to cleaning and disinfection than other pathogens. The virus’ efficiency in causing outbreaks “is more likely due to their extremely low infectious dose,” resulting in the requirement of a very low level of residual contamination in order to prevent further transmission. Fortunately, reducing the level of residual contamination to that low level is not that difficult and can be achieved without extreme measures.
