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.

Africa and EU – Rise in Antibiotic Resistance in Salmonella

Food Safety News

Strains of one increasingly antibiotic-resistant Salmonella serotype have seen a “rapid worldwide spread,” according to a study published by researchers at the Institut Pasteur in Paris and Morocco.

Antibiotic-resistant Salmonella Kentucky, first isolated in 2002 in a French tourist who had visited Egypt, has now “spread at an astonishing rate throughout Africa and the Middle East in the space of only a few years,” the study’s authors claim.

The bacterium has also already been found in farmed-raised turkeys in Europe, though it is not clear based on available information if those turkeys were imported or grown domestically. In a summary of the study, the lead author said he worries that the resistant strain may soon spread to European poultry farms.

This study comes on the heels of a report out of Canada calling antibiotic-resistant Salmonella Kentucky a rare but “growing concern” in Canadian health. That study found that between 2003 and 2009, 30 percent of Salmonella Kentucky isolates from Canadian patients were resistant to the antibiotic ciprofloxacin.

Netherlands- May Put Limits on Campylobacter on Chicken

Food Poisoning Bulletin imagesCAYZ5I84

A report from the National Institute for Public Health and the Environment in the Netherlands states that the Dutch government “intends to limit the level of Campylobacter bacteria on chicken meat, a so-called process hygiene criterion.” That means that if higher levels of the bacteria are found repeatedly in a particular slaughterhouse, that facility will need to evaluate their processing hygiene. The government has been focusing on “farm to fork” hygiene, looking at everything from slaughterhouse conditions to consumer food preparation standards.

USA – Recall Raw Ground Beef

E.coli BlogEcoli Istock

National Beef Packing Co., a Liberal, Kan., establishment, is recalling approximately 22,737 pounds of raw ground beef products that may be contaminated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

The problem was discovered through routine FSIS monitoring which confirmed a positive result for E.coli O157:H7. An investigation determined the firm was the sole supplier of the source materials used to produce the positive product. FSIS and the company have received no reports of illnesses associated with consumption of these products.

USA – Salmonella in Pet Food

Food Poisoning BulletinSalmonella

Natura Pet Products is recalling some lots of dry pet food because it may be contaminated with Salmonella bacteria. Pets can become ill after eating this food, and human beings can become ill just by touching it and then not thoroughly washing their hands. Pets with Salmonella can have lethargy and have diarrhea, which may be bloody, fever, and vomiting. Pets that appear perfectly healthy can be carriers of Salmonella bacteria.

The recalled products were packaged in one production facility. A single lot tested positive for Salmonella during routine FDA testing. No illnesses have been associated with these products to date. Natural is recalling all expiration dates before June 10, 2014.

USA – Hepatitis A Outbreak Grows

Food Safety NewsNorovirus

The Hepatitis A outbreak continues in eight western states with the case count as of June 14 rising to 106. The illnesses are blamed on an organic blend of frozen berries and pomegranate seeds from multiple countries.  Produced by Oregon-based Townsend Farms and sold at Costco and Harris Teeter stores, the frozen berry blend has caused Hepatitis A cases in Arizona, California, Colorado, Hawaii, Nevada, New Mexico, Utah, and Washington.

In an update today on its investigation, the federal Centers for Disease Control and Prevention in Atlanta profiled the cases based on available epidemiologic data from 94 of the 106 cases under investigation:

76 of 94 (81 percent) ill people interviewed reported eating “Townsend Farms Organic Anti-Oxidant Blend” frozen berry and pomegranate mix

Research – Microbiological Criteria as a Decision Tool for Controlling Campylobacter in the Broiler Meat Chain

NIPHE

Report

Substantiation of the standards for Campylobacter on chicken meat

Campylobacter bacteria are among the most important causes of foodborne disease in the Netherlands. Approximately 30 per cent of all cases of illness are attributed to the consumption and preparation of broiler chicken meat.

This mainly concerns cross-contamination in the kitchen from chicken meat to product that are consumed raw, like salads, and to a lesser extent under cooked meat. Research by RIVM has shown that a large point of these illnesses can be prevented if the number of bacteria on chicken meat after industrial production is reduced.

Recently there is increased attention for hygiene in the farm to fork production check including slaughterhouses. In this context, the Dutch government intends to limit the level of Campylobacter bacteria on chicken meat, a so-called process hygiene criterion. If higher levels are repeatedly found, the slaughterhouse needs to improved processing hygiene RIVM has evaluated the impact of different (more or less stringent) criteria, both on public health and on the costs for the poultry industry.

A critical limit of 1000 Campylobacter bacteria per gram would reduce the number of human disease cases by two-thirds. The costs to the poultry industry to meet this criterion (estimated at 2 million euro per year) are considerably lower than the averted costs of illness (approximately 9 million euro per year).

USA – E.coli Case

E.coli BlogEcoli Istock

Wellesley Health Department (WHD) received notice by the Massachusetts Department of Public Health’s (MDPH) surveillance system on June 12, 2013 of a case of E. coli in a Wellesley resident.

The origin of the cases’ illness is being investigated.

Rumors have been circulating that the cause of the illnesses has been linked to a local supermarket. At this point, no local supermarkets are a focus of the investigation.
