USA – Molida de Res Ground Beef Recalled For Possible E. coli O157:H7

Food Poisoning Bulletin

La Rosita Fresh Market of  Mount Prospect, Illinois, is recalling about 54 pounds of raw ground beef that may be contaminated with E. coli O157:H7 bacteria. No illnesses have been reported to date in association with this problem. That pathogen can cause serious illness and possibly hemolytic uremic syndrome (HUS) if ingested.

The beef was only sold at the La Rosita Fresh Market Inc. retail store. That facility is located at 1805 West Algonquin Road in Mount Prospect, Illinois.

The recalled products is Molida De Red Ground Beef in various weights. The product is packed in white trays covered with plastic wrap. The dates on the product are “Packed On 3/13/19 Sell By 3/20/19” and “Packed On 3/14/19 Sell By 3/21/19.”

France – E. coli O26/O157 and Salmonella behind French cheese recalls

Food Safety News


E. coli has prompted two different recalls of cheese and there has been one due to Salmonella in France in the past few weeks.

Recalls have been due to E. coli O26, E. coli O157 and Salmonella Montevideo but no illnesses have been reported.

Fromagère du Moulin de Carel recalled camembert from the supermarket Carrefour due to E. coli O26 H11.

The affected Camembert de Normandie 250-gram product has lot code of L19009C and date of March 10, 2019. It was beginning in late January.

The company, based in Saint-Pierre-sur-Dives, took the action after E. coli was detected during a microbiological control test.

Fromagère de Jort, based in Bernière d’Ailly, also recalled camembert made from raw milk from Carrefour and Auchan due to finding the same pathogen during a microbiological control.

Research – Survival of Salmonella enterica and Escherichia coli O157:H7 Sprayed onto the Foliage of Field-Grown Cabbage Plants

Journal of Food Protection

To reduce the number of cabbage pathogen outbreaks, it is essential to understand the fate of enteric pathogens that contaminate plants in the field. To assist in that effort, two independent trials were conducted with a red cultivar (cv. Red Dynasty) and a green cultivar (cv. Bravo F1) of field-grown cabbage (Brassica oleracea var. capitata). In the first trial, plants with small heads were sprayed with an inoculum containing both attenuated Salmonella enterica Typhimurium and Escherichia coli O157:H7 (5.0 log CFU/mL). Initial pathogen levels (ca. 3.9 log CFU per head), determined through plate count enumeration (limit of detection was 1.3 log CFU/g), dropped precipitously such that 2 days later, they could not be detected by enrichment culture in 22 to 35% of the heads. However, subsequent declines were at a slower rate; no differences were observed between red and green cabbage heads (P > 0.05), and heads were still positive for the pathogens 22 days after being sprayed with the inoculum. As a result, the logistic model revealed that for every 2 days contaminated cabbage heads remained in the field, the probability of finding a positive sample decreased by a factor of 1.1 (95% confidence interval from 1.0 to 1.2, P = 0.0022) and 1.2 (95% confidence interval from 1.0 to 1.4, P ≤ 0.0001) for Salmonella and E. coli O157:H7, respectively. In the second trial occurring 2 weeks later, plants with medium red or green cabbage heads were sprayed with an inoculum at a dose of 3.5 log CFU/mL. A similar decay in prevalence over time occurred for green cabbage as in trial 1; however, pathogen decline in red cabbage was less in trial 2 than in trial 1. The extended persistence of pathogens in cabbage heads exhibited in both trials infers that harvest of contaminated cabbage destined for raw consumption is risky. Additional field studies are necessary to determine whether similar pathogen fates occur in other regions or climates and to clarify the effect of the maturity of red cabbage on pathogen inactivation.

Research – Overview of Leafy Greens–Related Food Safety Incidents with a California Link: 1996 to 2016

Journal of Food Protection Eurofins Food Testing UK

An increase in the number of foodborne illness outbreaks associated with produce has been noted in the literature, and leafy greens have been the most common produce category associated with these outbreaks. California is the largest leafy greens producer in the United States, and many related foodborne illness incidents were traced to this state. A systematic overview of leafy greens incidents linked to California was conducted by the California Department of Public Health, Food and Drug Branch through analysis of complaints, routine surveillance sampling, disease outbreaks, and investigations covering 1996 to 2016. The goal was to develop a risk assessment tool to modernize emergency response efforts to foodborne illnesses related to leafy greens. A database including environmental, epidemiologic, and laboratory information for each incident was developed, and descriptive analysis was performed to identify trends. In the 21-year period analyzed, 134 incidents were identified, the majority of which were surveillance related. Approximately 2,240 U.S. cases of confirmed illness were reported (298 California cases resulting in 50 hospitalizations). Romaine lettuce and spinach were the most commonly implicated vehicles. The most prevalent hazard type was microbiological, in particular bacterial, specifically associated with pathogenic strains of Escherichia coli. In California, the overview provided the Food and Drug Branch with a platform to (i) enhance its Food Safety Program, Emergency Response Unit, and California Food Emergency Response Team; (ii) assist in more efficient investigation, response, control, and prevention of California-linked foodborne illness incidents; and (iii) identify knowledge gaps and develop effective definitions, procedures, training, guidelines, and policies that will be used to help prevent future outbreaks. Outcomes provide insight into the situation in the largest leafy greens–producing state and may be used to prioritize limited national food safety resources and aid in future leafy greens–related research and foodborne incident investigations.

Scotland – Scottish cheesemakers challenge guidance on raw milk in their products

Food Safety News

Five Scottish companies have launched a fundraising campaign for legal fees to challenge new inspection and enforcement guidance, including food safety measures, regarding raw milk cheese.

The guidance will effectively make production in Scotland unviable, according to the cheesemakers who specialise raw milk cheese.

It is focused on controlling microbiological risks in the production of artisan cheeses made from raw, unpasteurized milk such as Shiga toxin-producing E. coli (STEC) including E. coli O157 and applies to all sites producing cheese made from unpasteurized milk from cows, goats, sheep and buffalo.

The document was produced by a working group of the Scottish Food Enforcement Liaison Committee (SFELC) and is to be used during inspection and enforcement of food safety controls by cheesemakers making product from unpasteurised milk.

Selina Cairns from Errington Cheese told Food Safety News that to satisfy the cheesemakers the guidance needs to be removed or re-written in consultation with industry and individual cheesemakers.

Scotland – Food Standards Scotland issues warning over Shiga-toxi E.coli bug

Herald Scotland

FOOD safety inspectors have warned that even trace amounts of an E. coli bacteria can post a danger to human health.

The updated guidance from Food Standards Scotland (FSS) has been published today following a joint report by the World Health Organisation and United Nations which urged vigilance in relation to Shiga Toxin-producing E. coli (STEC).

Professor Norval Strachan, Independent Chief Scientific Adviser for FSS, said: “STEC, or Shiga Toxin-producing E. coli, are a group of different types of E. coli bacteria found in the guts of animals such as cattle and sheep, which can make their way into the food chain via the animals’ faeces.
