Research – Detection of foodborne viruses in ready‐to‐eat meat products and meat processing plants

Wiley Online

Abstract

Several studies have confirmed the presence of foodborne viruses in different food products throughout the world. There is accumulating data suggesting that the economic burden of foodborne viral infections is rising, making the understanding and monitoring of their prevalence a necessity, for the modern food industry. The objective of this study was to examine ready‐to‐eat meat products and environmental samples originated from meat processing plants in Cyprus, for four foodborne viruses: norovirus (NoV GGI, NoV GII), rotavirus, hepatitis A virus, and hepatitis E virus. A total of 48 swab samples and 42 different pork meat products from two plants were analyzed in parallel. The reverse transcription real‐time polymerase chain reaction revealed two swab samples from the same plant positive for norovirus GGI. The detection of norovirus on a slicer machine and on the hands of a worker, suggest that foodborne viruses can be present in meat processing environments.

Practical applications

There is an increasing need to better understand the prevalence of foodborne viruses in the environment and food, given the rise of viral foodborne outbreaks throughout the world, as reported by World Health Organization. Meat products form an important exposure vehicle to humans either directly, through the consumption of raw products, or as a result of cross‐contamination in food processing plants. This is the first report in Cyprus illustrating the presence of foodborne viruses in meat processing plants and the possible impact in public health, through the consumption of ready‐to‐eat meat products.

USA – Buffalo Wild Wings now Linked to Hepatitis A Outbreaks

Food Poison Journal

The Macomb County Health Department has confirmed a case of hepatitis A in a food service worker at a Buffalo Wild Wings restaurant in Warren.The restaurant at 29287 Mound was inspected Tuesday, according to a release from the health department. The eatery has been approved to operate, and management worked with the health department in the investigation.

The health department is advising anyone who ate at the restaurant from March 24 through April 9 to watch for symptoms of hepatitis A, which include abdominal pain, nausea, vomiting, diarrhea, dark urine, fever, chills and yellow skin and eyes or jaundice.

Symptoms can develop anywhere from 15 and 50 days after exposure, the health department said. People developing these symptoms should get medical care.

USA- Kentucky reports hep A death; Waffle House worker positive

Food Safety News

New hepatitis A infections continue to be diagnosed in Kentucky where almost 150 people have been confirmed with the virus. Health officials reported the state’s first death in the outbreak that has killed more than 40 people nationwide.

More bad news hit the headlines in the Bluegrass State this week as the Ashland-Boyd County Health Department reported on Tuesday that customers of both Waffle House restaurant locations in Boyd County were potentially exposed to the highly contagious virus by an infected foodservice worker.

“The single employee worked at each location during the infectious period,” according to the public health alert. “The window of possible exposure was Feb. 12-28.

UK Research- Norovirus in Food Outlets to be Mapped

Medical Press norovirus-2(1)

The University of Liverpool is leading a £2 million Food Standards Agency (FSA) project to map the occurrence of norovirus in food premises and industry workers.

Norovirus outbreaks can rapidly affect of people. In 2012 a batch of frozen strawberries infected 11,000 people in Germany, but there are significant gaps in the authorities’ understanding of which strains cause and which foods are the most likely to harbour the bacteria.

Researchers will produce data that will help the FSA to develop plans to reduce the infection by collecting swabs from work surfaces at more than 200 pubs, restaurants and hotels in the North West and South East of England.

UK – FSA – Consultation on Virus

FSA Virusds

The Advisory Committee on the Microbiological Safety of Food (ACMSF) is a scientific advisory committee that provides the FSA with independent expert advice. This helps the FSA ensure that policy development and consumer advice in relation to the microbiological safety of food are based upon sound science and relevant practical experience and expertise. The Committee’s terms of reference are to assess the risk to humans from microorganisms that are used or occur in or on food and to advise the FSA on any matters relating to the microbiological safety of food.

Since the publication of the 1998 ACMSF report on foodborne viral infections, with the exception of minor risk assessment work carried out on hepatitis E and avian influenza, no formal review has been carried out on foodborne viruses.

At the March 2010 ACMSF meeting the FSA asked the Committee to consider whether it was timely to carry out a review of foodborne viral infections, assessing the risk to consumers and highlighting any research and surveillance gaps.

The Committee agreed that an ad hoc group should be set up to revisit the issue of foodborne viruses in light of the significant developments in this area, so that an updated risk profile could be produced based on the findings.

The group met 13 times from November 2010 to July 2013 to assess the extent of viral foodborne infection in the UK.

The group considered information on all foodborne viruses including new and emerging viral pathogens and identified that the most important viruses associated with foodborne infection were norovirus, hepatitis A virus, and hepatitis E virus. These viruses are the focus of the group’s report, which concentrates mainly on viral foodborne infection in the UK. The report also gives consideration of two recent comprehensive reviews of viruses in food that have been published by WHO (2008) and EFSA (2011). The report provides key information that will be used to inform Risk Assessments and Risk Management on foodborne viruses across government.

The group’s draft report has now been approved by the full Committee and is attached for comment.

New Zealand – Hepatitis A in Fresh Fruit

The Ministry for Primary Industries (MPI) is cautioning New Zealand  consumers of a small quantity of fresh fruit sold in late February and early March  that there is a relatively low risk that this fruit had been contaminated with  Hepatitis A virus.

MPI Deputy Director General Scott Gallacher says it is important that  consumers understand the risk of transmission of the virus is relatively low,  but MPI is issuing this information as a precaution so that people with any  related concerns about their health can contact their doctor.

“As always, MPI is placing the health and wellbeing of all consumers  first.

“We have been advised that a person packing some varieties of apples  and peaches in a Hawke’s Bay packhouse has been diagnosed with Hepatitis A.
