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.

UK – London – Norovirus Outbreak

London Evening Standard

A Primrose Hill school was closed today after more than 200 pupils and 15 members of staff were struck down with the contagious Norovirus.

Health inspectors ruled the winter vomiting bug was present at North Bridge House Preparatory School. The building in Gloucester Avenue was being cleansed today amid fears the virus could spread to the school’s other buildings.

In a letter sent to parents, headteacher Brodie Bibby said the school was “afflicted by a particularly unpleasant virus.”

Any children showing signs of sickness were told to be kept at home by parents, she wrote – adding that any children still well enough were invited to attend a planned performance of Swan Lake tomorrow night.

She added that “a specialist team will clean the entire school with anti-viral sprays and use air-based products.”

One parent told a local newspaper that his daughter “suddenly turned white and projectile vomited all over her bedroom” after being struck down with the illness this week.

North Bridge House, which also has a nursery school, a junior and a senior school at different sites in Camden, will reopen on Monday.

USA – E.coli Outbreak Linked to Unpasteurised Cider

Food Poisoning Bulletin

The Health Department of Northwest Michigan, along with Community Health and the Michigan Departments of Agriculture and Rural Development are investigating a series of E. coli infections that may be associated with unpasteurized, unlabeled apple juice in Antrim County. Officials are collecting stool samples and samples of the cider to test for the outbreak strain of the bacteria.

The cider was made by an unlicensed facility and was not labeled as unpasteurized.

Belgian – Research – Grape Seed Extract Reduces the Infectivity of Norovirus

HACCPEUROPA – Full Article

Norovirus causes more than half of all food-borne illnesses in the United States, and is the second greatest source of reported food borne illness outbreaks in the European Union. A norovirus is a small virus that contains RNA and is surrounded by a protein coating. By sequencing the RNA, scientists have discovered that there are many different types of norovirus. Originally, strains were named based on the city in which they were first identified. Thus, one common strain used to be called Norwalk virus. Based on genetic typing, we now know that there are at least 25 different strains of norovirus that affect humans.

A recent study found that grape seed extract could reduce the infectivity of Norovirus surrogates.

Researchers from Ghent University, Belgium have shown that grape seed extract does so by denaturing the capsid protein, which is the coat of the virus, thereby disabling the virus.

In the study, the researchers observed that under treatment with grape seed extract, at low doses, the spherically-shaped murine (mouse) norovirus-1 coat proteins clumped, and showed obvious deformation and inflation. At higher doses, the researchers saw no coat proteins, only protein debris. This provides evidence that grape seed extract could effectively damage the norovirus capsid protein, which could reduce viral binding ability and infectivity accordingly.

UK – Another Crusie Ship Virus Outbreak

BBC News

A cruise ship delayed its departure from Southampton after a suspected outbreak of norovirus on board. Celebrity Cruises’ vessel Constellation arrived in the city’s port at 06:00 GMT at the end of a 12-night cruise. Southampton’s Port Health Authority said about 350 passengers had fallen ill with the vomiting and diarrhoea bug. Its departure was delayed until 20:00 while deep cleaning took place.

The authority’s Rosie Zambra confirmed it was informed of “concerns over an increased levels of what appeared to be norovirus” several days before the ship’s arrival.

USA – Norovirus Outbreak at a Restaurant

Food Safety News 

At least 39 people fell ill with Norovirus infections after eating at a restaurant in central Illinois last week, according to the local health department.

All of those sickened were among a group of 80 people who attended an end-of-year banquet for a high school soccer team at Alexander’s Steakhouse in Peoria, IL October 28, reported the Peoria Journal Star.

Though the restaurant served a total of 1,100 meals the weekend the banquet was held, no patrons other than those who attended the banquet contracted the virus.

Victims experienced typical symptoms of Norovirus infection, including vomiting, diarrhea and abdominal cramps.

CDC Letter – UK Shellfish Market and Viruses – Hepatitis E

CDC (full letter)

Bivalve mollusks (shellfish), such as mussels and oysters, are filter feeders; they concentrate microorganisms of human and animal origin (up to 100×) from the surrounding environment. Several recent reports have linked the incidence of human infection with hepatitis E virus (HEV) to consumption of undercooked pork, game products, and shellfish (1,2). Infectious HEV has been found in swine manure and wastewater (3); therefore, application of manure to land and subsequent runoff could contaminate coastal water, leading to contamination of shellfish and, subsequently, possible human infection. Because they are filter feeders, bivalve mollusks are biologically relevant sentinels and can indicate potential pathogens that are contaminating the environment. It is essential to ensure that this sustainable resource of coastal areas, where mussels and oysters are farmed or collected wild, is not subjected to environmental contamination that could lead to public health risks.

Risk management for bivalve mollusks, aimed at control of fecal pollution, relies heavily on the use of Escherichia coli as an indicator of fecal (sewage) contamination and is enacted under European food regulations (Regulation 854/2004, www.cefas.co.uk/media/455777/extract_reg_no_854_2004.pdf Adobe PDF file). However, although these regulations probably reduce the number of infections, especially bacterial infections, they are not viewed as adequately controlling the risk for viral infections. Specific risks are posed by the robustness of viruses in the environment and the different behavior of viruses within bivalve mollusks compared with behavior within bacterial fecal indicators.

Canada – Montreal – Norovirus Hospital Outbreak

CBC News

An outbreak of norovirus among staff members at Montreal’s Jewish General Hospital led to the temporary closure of the hospital’s neurology clinic last week, CBC has learned.

About 45 employees at the hospital came down with gastrointestinal symptoms, including diarrhea, cramps and fever, after eating food that may have originated in an in-house catering service that is only used by staff.

The service is run by the hospital’s Atrium Café, a franchise operated by a volunteer auxiliary, which also serves hundreds of staff and visitors to the hospital each day.

The coffee shop is independent of the hospital’s main cafeteria.

“We closed the coffee shop immediately on Thursday afternoon,” said hospital spokesman Glenn Nashen. “Tests were done all day Friday, and although nothing has been conclusive at this point, the suspicion is that [the virus] may have come from this catering service.”

Nashen said as far as the hospital knows, only staff at the hospital caught the virus.

So many staff members in the neurology department fell ill that the neurology clinic had to be closed for half a day on Thursday and all of Friday.

The neurology clinic is expected to be open again on Monday.

Until the infection prevention and control team determines the specific cause of the outbreak, the coffee shop will remain closed, Nashen said

Australia/NZ – Warning Shellfish Biotoxin – PSP

FSANZ – Full information at this linkPSP

Food Standards Australia New Zealand (FSANZ) today urged consumers to check their fridges for recalled mussels that may be contaminated with a naturally occurring marine biotoxin (paralytic shellfish toxin).

The presence of a paralytic shellfish toxin arising from a naturally-occurring algal bloom in Tasmania has forced the closure of Spring Bay Seafood’s shellfish farm and the business has initiated a recall of its mussels from the market.

The products recalled are branded Spring Bay live blue mussels (with use by dates of between 22 October 2012 – 10 November 2012) and Coles Cooked Tasmanian mussels (use by date 12 November 2012) have been supplied by Spring Bay Seafoods Tasmania and have been distributed to TAS, VIC, NSW, ACT, SA, QLD and some Asian countries.

The affected mussels were supplied in shell and supplied in the quantities of 500g and 1kg vacuumed packed bags (Spring bay seafood), 500g (Coles branded – cream white wine sauce) and 1kg and 2kg net bags (Spring Bay seafood). They may also be supplied loose in shell/ per kg.
