Hong Kong – Recall Australian Cheese Implicated in the Listeria Outbreak

Center for Food SafetyFood Testing

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department today (January 21) urged the public not to consume certain soft cheese products, manufactured in Australia, which might have been contaminated with Listeria monocytogenes. The trade should stop selling the concerned products.

“The CFS noticed through its routine Food Incident Surveillance System that some cheese products produced by an Australian manufacturer, Jindi Cheese Pty Ltd, were suspected to be contaminated with Listeria monocytogenes.  The concerned company is now voluntarily recalling all soft and semi-soft cheese products it manufactured on or before January 6 this year,” a spokesman for the CFS said.

“The CFS subsequently received notification from the International Food Safety Authorities Network of the World Health Organisation / the Food and Agriculture Organisation of the United Nations that some of the affected products have been imported to Hong Kong,” he added.

According to the information provided by the Australian authorities, the CFS has contacted two chain stores which had imported the affected products, namely PARKnSHOP and Pacific Gourmet. The shops were instructed to stop selling the products concerned (see attached table). The CFS was also informed that the companies had set up hotlines to answer consumers’ enquiries about the product recall, PARKnSHOP at 2606 8658 and Pacific Gourmet at 3184 0805.

“In case any consumers have bought the affected soft cheese products, they should stop eating them, regardless of batches. To be prudent, consumers who recently bought any cut portion of gourmet soft cheese and are unsure of the product details should also stop eating it. People are advised to seek medical advice if they feel sick after consuming the products concerned. So far the CFS has not received any reports of persons feeling unwell after consumption of the affected products,” the spokesman said.

Research – Norovirus and Hand Sanitisers

Food Poisoning Bulletinnorovirus-2(1)

In 2011, the Centers for Disease Control and Prevention conducted a study that looked at a substantial increase in novovirus illnesses in northern New England. Researchers looked at long-term care facilities in that area, trying to identify institutional risk factors for norovirus outbreaks. State health departments in Maine, New Hampshire, and Vermont used surveys, collecting information about facility attribvutes, routine staff use of alcohol-based hand sanitizer versus soap and water, facility cleaning practices, and occurrence of acute gastroenteritis outbreaks from December 2006 to Amarcy 2007.

Norovirus outbreaks peak in the winter months, when people are forced to spend more time together. Cruise ships, hospitals, and nursing homes usually suffer outbreaks because of the proximity of patients. The virus is extremely contagious and people can become infected through food and drink, person-to-person, and by touching contaminated surfaces.

The surveys found that of the 91 facilities that responded, 61 reported 73 outbreaks in that time frame. Of those outbreaks, 29 were confirmed norovirus. And facilities where staff were “equally or more likely to use alcohol-based hand sanitizer (ABHS) than soap and water for routine hand hygiene had higher odds of an outbreak than facilities with staff less like to use ABHS.”

UK – Takeaway Owner Jailed for E.coli Outbreak

BBC NewsEcoli Istock

The owner of a Cardiff takeaway has been jailed for eight months following an outbreak of E. coli.

Diar Wali Ali admitted at Cardiff magistrates’ court to 23 food hygiene offences and was jailed on Monday.

In August 2011, nine customers fell ill with food poisoning after visiting the Adonis Kebab House in City Road, Roath.

The takeaway was closed for two weeks while inspections were carried out and the council was satisfied the risks had been removed.

Councillor Derek Morgan, chair of Cardiff council’s public protection committee, said people had a right to eat safe food and certain levels of hygiene.

“However, where poor hygiene practices and substandard conditions are found, we take immediate action to safeguard public health,” he said.

“I hope this case helps to show how seriously we take this commitment and demonstrate that, where appropriate, we will use the full force of the law to ensure food safety regulations are met.”

USA – Raw Milk STEC Outbreak

 Food Poisoning Journal

The Missouri Department of Health and Senior Services (DHSS) has become aware of several cases of diarrheal illness from northwest Missouri, possibly caused by Shiga-toxin producing Escherichia coli (STEC), including one confirmed as E. coli O103. These may be related to the consumption of locally-produced, raw (unpasteurized) dairy products.

DHSS recommends that any person who has signs or symptoms of STEC infection seek medical care. Health care providers should evaluate patients adequately to determine if testing for STEC infection is warranted.

Symptoms of STEC infection include severe stomach cramps, diarrhea (which is often bloody), and vomiting. If there is fever, it usually is not very high. Most patients’ symptoms improve within 5–7 days, but some patients go on to develop hemolytic uremic syndrome (HUS), usually about a week after the diarrhea starts. The classic triad of findings in HUS are acute renal damage, microangiopathic hemolytic anemia, and thrombocytopenia.

Australia New Advice About Listeriosis – Rising Number of Cases

NSW Food Authority

The NSW Food Authority advises those most at risk to avoid the following ready to eat foods:

  • soft cheese such as brie, blue, fetta, camembert and ricotta
  • cold chicken or turkey particularly if sliced or diced – such as used in chicken sandwiches
  • cold meats, pate and meat spreads
  • pre-prepared or packaged salads greens and salads
  • raw seafood such as oysters, sashimi, smoked salmon or oysters (canned oysters are safe)
  • sushi
  • unpasteurised dairy products including raw goat’s milk and Roquefort cheese

“Signs of listeriosis include flu-like symptoms such as fever, muscle aches, nausea and diarrhoea that can sometimes lead to septicemia, meningitis and in some cases, miscarriage in pregnant women,” Dr McAnulty said.

Investigations into listeriosis are complex as it can be difficult to identify the source. Symptoms of illness can take up to 70 days to appear.

Healthy people usually show only mild symptoms. However, in people at risk, early symptoms of listeria infection include fever, headache, tiredness and aches and pains.

Research – Campylobacter in Chicken Factory Workers

Food Safety NewsimagesCAYZ5I84

New analysis of Campylobacter infections among workers at a Virginia poultry plant offers hints about which employees more likely to fall ill from the bacteria.

Government researchers examined health data for plant employees from January 2008 through May 2011 and found that 29 Campylobacter cases had been confirmed during that time period.

Their findings reveal three characteristics of workers who were more likely to be sickened:

  • Recently employed: A full 83 percent of these patients had worked at the plant less than a month before falling ill, suggesting that illness is more common among new employees.
  • Worked in the live-hang area: Those whose job involved hanging live chickens were far more likely to be infected than those working in other parts of the facility. Of those sickened, 62 percent worked in a live-hang area.
  • Resided in diversion centers: Almost all the employees who contracted Campylobacter infections (26 out of 29) lived in state-operated diversion centers. The authors say the high illness rate among this group may be due to the fact that diversion center residents are disproportionately assigned to live-hang areas, where they are more likely to be exposed to the bacteria.

The fact that new employees fell ill more frequently than those who had been there more than a month is consistent with findings from other studies, which have suggested that workers develop immunity to the bacteria during the first few weeks of work.

Canada – E.coli O157 Outbreak Update

Food Safety NewsEcoli Istock

Canada’s eastern and adjoining provinces of Nova Scotia and New Brunswick are reporting 15 confirmed cases of E. coli O157:H7. None of the illnesses have yet been traced to a source.

Ten of the E. coli illnesses are located in central Nova Scotia, with five reported by the Capital District Health, two by the Guysborough Antigonish Strait Health Authority, and one each by the Pictou, Cumberland, and Colcherster East Hants health authorities.

On the other side of the Bay of Fundy in New Brunswick, heath officials reported two cases were reported in the St. John region and three in the Fredericton region.

Dr. Eilish Cleary, chief medical officer for New Brunswick, said it is not known if there is a common source for the cases. A number of possible sources are being investigated. Dr. Robert Strang, chief medical officer for Nova Scotia, said that it would not be uncommon for there to be additional cases as it may take as long as ten days for some people to begin to experience symptoms of E. coli O157:H7 and get tested.

One of the Nova Scotia patients experienced kidney failure, but along with the others is said to be recovering. In New Brunswick, four illnesses were treated by emergency room visits, and one victim was hospitalized.

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.
