European Epdiemiological Report into the Salmonella Stanley Outbreak 2012

ECDCecdclogo

In July 2012, the European Centre for Disease Prevention and Control (ECDC) initiated a Europe-wide investigation on a Salmonella Stanley outbreak, together with the affected Member States, the European Food Safety Authority (EFSA) and the European Reference Laboratory for Salmonella (EURL Salmonella). Cases were associated with strains showing an indistinguishable PFGE pattern not previously reported in Europe.

Between July and September 2012, ECDC encouraged European Union (EU) and other European Economic Area (EEA) Member States to perform Xbal-PFGE typing on all S. Stanley human isolates. The image profile of the outbreak strain was shared with all EU countries. ECDC collected and analysed molecular typing data on S. Stanley from EU/EEA Member States to explore potential sources of infection within the food production chain in this multi-country outbreak.

UK – HPA Update on Norovirus Activity

HPANorovirus

Latest figures from the Health Protection Agency (HPA) show there have been 4,140 laboratory confirmed cases of norovirus this season (from week 27 to week 52 2012). The latest figures are 63 per cent higher than the number of cases reported at this point last year, when there were 2,535 cases.

The downward trend in the number of confirmed cases has continued in line with the previous report although this is to be expected following the Christmas and New Year period. We will expect to see the number of cases increase again over the following few weeks.

During the two weeks up to 6 January there were 33 hospital outbreaks reported, compared to 30 in the previous fortnight, bringing the total of outbreaks for the season to 673.

The Thunder Bay District Health Unit confirmed Friday that it was the Norovirus that caused an outbreak of gastrointestinal illness that affected dozens of people.

Maltese Grocery had shut down its catering operations temporarily after 85 people became sick after eating food at three events the company had catered the previous week. They’ve since resumed, but with additional precautions.

Senior Public Health Inspector Abby Mackie said clinical specimens submitted to a lab confirmed the Norovirus to be the source of the outbreak.

USA – Colorado

DENVER— The Colorado Department of Public Health and Environment is reporting widespread gastrointestinal illness (norovirus) throughout Colorado, including in nursing homes, assisted living facilities, schools and child care centers. Everyone is encouraged to increase simple prevention measures to stop further spread of illness in the community. Symptoms of the illness include nausea, vomiting, diarrhea and stomach cramping.

Alicia Cronquist, epidemiologist at the department, said, “We believe the illness is being caused by a virus germ called norovirus. This infection is very common this time of year.

MIYAZAKI — Six patients have died of gastroenteritis caused by a norovirus outbreak at Shunkokaihigashi Hospital in Nichinan, Miyazaki Prefecture, hospital officials said Sunday.

The victims — all men aged between 78 and 88 — were among 44 patients and staff who came down with symptoms of the illness, including vomiting and diarrhea, the officials said. All six were bedridden.

The health ministry has issued a nationwide warning about the norovirus because infections are approaching the record high set in 2006.

TAIPEI–Health experts said Tuesday that an unusually high number of diarrhea cases have been reported this winter due to norovirus outbreaks and it warned that the peak season is yet to come.//

About 10,108 patients sought treatment for watery diarrhea at emergency departments across the country last week, which was a five-year high, said Chuang Jen-hsiang, director of the Epidemic Intelligence Center at the Centers for Disease Control (CDC).

Research Norovirus Spread by Kitchen Untensils

Sprenger LinkNorovirus

Abstract

Human noroviruses and hepatitis A virus (HAV) are commonly associated with outbreaks occurring in restaurant establishments and catered events. Food handlers are major contributing factors to foodborne illnesses initiated in the kitchen setting. In this study, transfer of HAV and murine norovirus (MNV-1), a human norovirus surrogate, between produce (cucumbers, strawberries, tomatoes, cantaloupes, carrots, and honeydew melons) and common kitchen utensils (graters and knives) was investigated. The extent of virus transfer to produce during utensil application, in the presence and the absence of food residue, and the impact of knife surface properties (sharp, dull, serrated) was also investigated. Transfer of MNV-1 and HAV from produce items, initially contaminated with ~5.5 log PFU, to knives and graters during application ranged from 0.9 to 5.1 log PFU. MNV-1 transfer to knives was the greatest for cucumbers, strawberries, and tomatoes, and the least for honeydew melons, while transfer of HAV to knives was greater for tomatoes and honeydew melons than strawberries, cantaloupes, and cucumbers. After preparation of a contaminated produce item, knife cross-contamination easily occurred as viruses were detected on almost all of the seven produce items successively prepared. Produce residues on utensils often resulted in less virus transfer when compared to utensils without residue accumulation. Knife surface properties did not impact virus transfer. The ease of virus transfer between produce and utensils demonstrated by the current study highlights the importance of efforts aimed toward preventing cross-contamination in the kitchen environment

 

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.

UK – Another Crusie Ship Virus Outbreak

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.

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
