USA – Townsend Farms – Berry -Hepatitis A

Food Poisoning JournalClose up 3d render of an influenza-like virus isolated on white

Townsend Farms, Inc. of Fairview, Oregon, out of an abundance of caution and in cooperation with the FDA is expanding its voluntary recall efforts and is now recalling Townsend Farms Organic Antioxidant Blend, 3 lb. bag with UPC 0 78414 40444 8. The recall codes are located on the back of the package with the words “BEST BY” followed by the code T122114 sequentially through T053115, followed by a letter. All letter designations are included in the voluntary recall. The voluntary recall is occurring because of a potential hepatitis A contamination. The voluntary recall efforts are based on epidemiological and trace-back evidence resulting from an ongoing outbreak investigation conducted by the FDA and the CDC. Photos of the package are attached.

Hepatitis A is a contagious liver disease that results from exposure to the hepatitis A virus, including from food. It can range from a mild illness lasting a few weeks to a serious illness lasting several months. Illness generally occurs within 15 to 50 days of exposure and includes fatigue, abdominal pain, jaundice, abnormal liver tests, dark urine and pale stool. Hepatitis A vaccination can prevent illness if given within two weeks of exposure to a contaminated food. In rare cases, particularly consumers who have a pre-existing severe illness or are immune-compromised, hepatitis A infection can progress to liver failure.

Food Safety News

The Hepatitis A outbreak linked to frozen mixed berries continues to grow. On Friday, the Centers for Disease Control and Prevention said five more illnesses have been confirmed as part of the outbreak, bringing the total to 127 ill in 8 states, and the U.S. Food and Drug Administration said it thinks it has identified a common shipment of pomegranate seeds from Turkey that may have been to blame.

According to CDC, all of the confirmed victims became ill after eating Townsend Farms Organic Anti-oxidant Blend, a frozen berry blend sold across the country in Costco stores. Harris Teeter also sold the now recalled product, but so far no illnesses have been linked to the retailer.

UK – FSA Annual Food Incidents Report

FSA food_standards_agency_logo

The Food Standards Agency has today published its latest Annual Report of Food Incidents. The report highlights the wide range of incidents managed by the Food Standards Agency during 2012.

Last year, a total of 1,604 food and environmental contamination incidents in the UK were reported to and investigated by the FSA. This figure was 110 down on 2011 but higher than in many previous years. The three largest contributors to these incidents were microbiological contamination (20%), environmental contamination (15%) and natural chemical contamination (13%).

One of the valuable roles played by the report is providing insight into why certain types of incident have increased. For example, FSA investigations show a recent rise in a certain type of salmonella was mostly the result of paan leaves imported from Bangladesh. Similarly, the number of allergen-related incidents appears to have risen by more than half since 2010. Statistics suggest, however, that legislative changes relating to gluten may have been a major contributory factor.

The report also shows a rise in the number of whistleblowers who contacted the FSA during the year. A total of 81 cases originated from whistleblowers during 2012 – up from 54 the previous year.

Catherine Brown, Chief Executive of the Food Standards Agency, said: ‘We hope that this annual report encourages food businesses and consumers to notify us promptly of incidents and of any other potentially-useful intelligence they have. This will enable us to act swiftly to protect the public and the food industry and, in so doing, increase public confidence in food safety.’

The data released today does not include the incidents of horsemeat contamination that came to light in the first half of 2013, as these occurred outside of the scope of the report. All incidents notified to the FSA are reviewed, and in the case of horsemeat the FSA has commissioned an additional independent external review of how it responded. This is due to report shortly.

Catherine Brown said: ‘Although the horsemeat incident occurred outside the scope of this report, I would like to highlight the resolve with which the FSA responded. Working closely with other Government departments and the food industry, the Agency ensured that 6,000 tests of frozen products were carried out within three weeks – far more than any other EU member state. The UK was also the first country to submit a dossier to Europol and the first country to make arrests.

‘By responding so quickly, we were able to reassure the public that more than 99% of the tests undertaken in the UK contained no horse DNA at the level of 1% or above, and that there was no threat to public health.’

Research – FDA Investigation Safety of Shell Eggs

Food Posioning BulletinEGGS

The Food and Drug Administration (FDA) is planning to establish a Cooperative Agreement with the North Carolina State University Department of Poultry Science and the Piedmont Research Station Poultry Unit to study the safety of shell eggs in the U.S. market. The 2009 Egg Safety Rule was designed to prevent foodborne illness caused by eggs contaminated with Salmonella Enteritidis. The Agreement will research routes of transmission for Salmonella in the egg production industry. The agreement will go into effect in September 2013.

Scientists are hoping to investigate how changes in physical feed characteristics and housing could influence Salmonella transmission. Findings will help researchers and the egg industry understand routes of Salmonella transmission and food safety controls needed to help prevent outbreaks.

Europe – Laboratory Preparedness for Detection and Monitoring of Shiga Toxin 2-producing Escherichia coli O104:H4 in Europe and Response to the 2011 Outbreak

Eurosurveillance

A hybrid strain of enteroaggregative and Shiga toxin 2-producing Escherichia coli (EAEC-STEC) serotype O104:H4 strain caused a large outbreak of haemolytic uraemic syndrome and bloody diarrhoea in 2011 in Europe. Two surveys were performed in the European Union (EU) and European Economic Area (EEA) countries to assess their laboratory capabilities to detect and characterise this previously uncommon STEC strain. Prior to the outbreak, 11 of the 32 countries in this survey had capacity at national reference laboratory (NRL) level for epidemic case confirmation according to the EU definition. During the outbreak, at primary diagnostic level, nine countries reported that clinical microbiology laboratories routinely used Shiga toxin detection assays suitable for diagnosis of infections with EAEC-STEC O104:H4, while 14 countries had NRL capacity to confirm epidemic cases. Six months after the outbreak, 22 countries reported NRL capacity to confirm such cases following initiatives taken by NRLs and the European Centre for Disease Prevention and Control (ECDC) Food- and Waterborne Disease and Zoonoses laboratory network. These data highlight the challenge of detection and confirmation of epidemic infections caused by atypical STEC strains and the benefits of coordinated EU laboratory networks to strengthen capabilities in response to a major outbreak.

Research – Listeria in Cheese and Milk

Wiley Online

According to Codex Alimentarius Commission recommendations, management options applied at the process production level should be based on good hygiene practices, HACCP system, and new risk management metrics such as the food safety objective. To follow this last recommendation, the use of quantitative microbiological risk assessment is an appealing approach to link new risk-based metrics to management options that may be applied by food operators.

Through a specific case study, Listeria monocytogenes in soft cheese made from pasteurized milk, the objective of the present article is to practically show how quantitative risk assessment could be used to direct potential intervention strategies at different food processing steps.

Based on many assumptions, the model developed estimates the risk of listeriosis at the moment of consumption taking into account the entire manufacturing process and potential sources of contamination. From pasteurization to consumption, the amplification of a primo-contamination event of the milk, the fresh cheese or the process environment is simulated, over time, space, and between products, accounting for the impact of management options, such as hygienic operations and sampling plans. A sensitivity analysis of the model will help orientating data to be collected prioritarily for the improvement and the validation of the model.

What-if scenarios were simulated and allowed for the identification of major parameters contributing to the risk of listeriosis and the optimization of preventive and corrective measures.

Dairy Foods

In 1985, the world changed for the dairy industry. The New England Journal of Medicine reported that from Jan. 1 to Aug. 15, there were 142 confirmed cases and 48 deaths associated with listeriosis, a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes.

The cases were centered in the local Hispanic population of Los Angeles. These were “confirmed” cases; however, the actual number is estimated to be significantly higher. The outbreak was eventually linked to Jalisco Mexican Products Inc., commonly known as “Jalisco Cheese.” Investigators determined that an unknown portion of the milk used to make the company’s fresh Mexican-style cheeses was not pasteurized. This was not by mistake. Raw milk added to pasteurized milk enhanced the flavor of the cheese, giving it a slight rancid flavor.

At the time, we knew virtually nothing about Listeria. We were asking:

  • What is it and how pathogenic is it?
  • Where did it come from?
  • How does it grow?
  • Can we control it?

But the most important questions in 1985 were: Will sanitizers destroy it and does it survive pasteurization?

India – Food Poisoning 56 University Students

The New Indian Expressimages

Around 56 students of  the women’s hostel of the Kerala University’s Kariavattom campus had to be taken to Medical College hospital after suspected food poisoning.

According to Medical College Hospital authorities,  none of the students is in a serious condition.

The students developed uneasiness and some of them vomited after having dinner, reportedly rice and fish curry, served at the hostel mess.

The hostel was shifted to a new building two weeks ago and students allege that the mess was not being run in hygienic conditions.  Most of the students were discharged from the hospital after being administered first aid.

UK – Curry Leaves cause Salmonella Outbreak 400 People

The Guardian

Uncooked curry leaves in a chutney left more than 400 people who ate at a street food festival with diarrhoea and vomiting or salmonella poisoning, health officials have found.

The leaves were contaminated with several different bacteria, experts found, which led to 29 confirmed cases of salmonella at the Street Spice festival in Newcastle in February and March.

An investigation by Public Health England (PHE) and Newcastle city council found 25 of the 29 cases had developed a strain of salmonella never found in people or food in Britain before.

According to an official report, further laboratory analysis suggested other organisms may also have caused illness including E coli and shigella.

Some of the 413 affected were found to have more than one of these infections at the same time.

No one will face prosecution because there was seen to be a lack of clear advice about the dangers of using raw curry leaves in recipes, and in general hygiene levels at the three-day event were good.
