USA – Interstate Meat Dist. Inc., Recalls Ground Beef Products Due To Possible E. Coli O157:H7 Contamination

FSIS USDA

WASHINGTON, Jan. 6, 2022 – Interstate Meat Dist. Inc., a Clackamas, Ore., establishment, is recalling approximately 28,356 pounds of 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 raw, ground beef items were produced on Dec. 20, 2021. The products subject to recall and the labels can be viewed here.

The products subject to recall bear establishment number “EST. 965” inside the USDA mark of inspection or printed next to the time stamp and use or freeze by date. These items were shipped to retail locations in Arizona, California, Nevada, Oregon, Utah, Washington and Wyoming.

The issue was reported to FSIS after a retail package of ground beef was purchased and submitted to a third-party laboratory for microbiological analysis and the sample tested positive for E. coli O157:H7.  FSIS conducted an assessment of the third-party laboratory’s accreditation and methodologies and determined the results were actionable.

Anyone concerned about an illness should contact a healthcare provider. E. coli O157:H7 is a potentially deadly bacterium that can cause dehydration, bloody diarrhea and abdominal cramps 2–8 days (3–4 days, on average) after exposure the organism. While most people recover within a week, some develop a type of kidney failure called hemolytic uremic syndrome (HUS). This condition can occur among persons of any age but is most common in children under 5-years old and older adults. It is marked by easy bruising, pallor, and decreased urine output. Persons who experience these symptoms should seek emergency medical care immediately.

FSIS is concerned that some product may be in consumers’ refrigerators or freezers. Consumers who have purchased these products are urged not to consume them. These products should be thrown away or returned to the place of purchase.

FSIS routinely conducts recall effectiveness checks to verify recalling firms notify their customers of the recall and that steps are taken to make certain that the product is no longer available to consumers. When available, the retail distribution list(s) will be posted on the FSIS website at www.fsis.usda.gov/recalls.

FSIS advises all consumers to safely prepare their raw meat products, including fresh and frozen, and only consume ground beef that has been cooked to a temperature of 160 °F. The only way to confirm that ground beef is cooked to a temperature high enough to kill harmful bacteria is to use a food thermometer that measures internal temperature, https://www.fsis.usda.gov/safetempchart.

Consumers and members of the media with questions about the recall can contact Sales Manager Mike Sinner and Quality Assurance Manager Rodolfo Mendoza, Interstate Meat Dist., Inc., at (503) 656-6168.

Research – Evaluation of microbial contamination in cold dishes and Prevalence of food-borne pathogens in the Jilin Province

Journal of Food Protection

In this study, we evaluated the microbial contamination status of cold dishes consumed by residents of Jilin Province and investigated to determine the incidence of four pathogenic bacteria in cold dishes. A total of 300 samples of cold dishes including meat, vegetable and mixed products, were collected from three different purchasing places: supermarkets, farmers’ markets and mobile vendors. Live bacteria were isolated using conventional culture methods. After separation, a quick and easy polymerase chain reaction (PCR) was used to detect Listeria monocytogenes , Staphylococcus aureus , Enterotoxic Escherichia coli and Salmonella . The results showed that the total number of microbial colonies in the vegetable samples exceeded the standard rate of 8%, and the total number of microbial colonies in the meat and mixed samples did not exceed the standard. The total microbial colony count exceeded the standard in all three different procurement sites, with the highest exceedance of 7.4% in the mobile vendor sites. The detection rates of Enterotoxigenic Escherichia coli , Staphylococcus aureus , L. monocytogenes and Salmonella among the four pathogenic bacteria detected in all samples were 4.3%, 3.3%; 3.0%; and 1.0%, respectively. This study can be used to qualitatively assess the microbiological quality associated with cold dishes. It provides data to support the detection of possible food safety problems.

Research -A trait-based framework for predicting foodborne pathogen risk from wild birds

Wiley Online

Recent foodborne illness outbreaks have heightened pressures on growers to deter wildlife from farms, jeopardizing conservation efforts. However, it remains unclear which species, particularly birds, pose the greatest risk to food safety. Using >11,000 pathogen tests and 1,565 bird surveys covering 139 bird species from across the western U.S.A., we examined the importance of 11 traits in mediating wild bird risk to food safety. We tested whether traits associated with pathogen exposure (e.g., habitat associations, movement, and foraging strategy) and pace-of-life (clutch size and generation length) mediated foodborne pathogen prevalence and proclivities to enter farm fields and defecate on crops. Campylobacter spp. were the most prevalent enteric pathogen (8.0%), while Salmonella and Shiga-toxin producing E. coli (STEC) were rare (0.46% and 0.22% prevalence, respectively). We found that several traits related to pathogen exposure predicted pathogen prevalence. Specifically, Campylobacter and STEC-associated virulence genes were more often detected in species associated with cattle feedlots and bird feeders, respectively. Campylobacter was also more prevalent in species that consumed plants and had longer generation lengths. We found that species associated with feedlots were more likely to enter fields and defecate on crops. Our results indicated that canopy-foraging insectivores were less likely to deposit foodborne pathogens on crops, suggesting growers may be able to promote pest-eating birds and birds of conservation concern (e.g., via nest boxes) without necessarily compromising food safety. As such, promoting insectivorous birds may represent a win-win-win for bird conservation, crop production, and food safety. Collectively, our results suggest that separating crop production from livestock farming may be the best way to lower food safety risks from birds. More broadly, our trait-based framework suggests a path forward for co-managing wildlife conservation and food safety risks in farmland by providing a strategy for holistically evaluating the food safety risks of wild animals, including under-studied species.

USA – Dangerous E. Coli O157 Found in Ground Beef Sold at Kroger and Fred Meyer Supermarkets

Consumer Reports

Kroger-brand ground beef purchased at a Fred Meyer supermarket in Seattle and tested by Consumer Reports was found to have a deadly strain of E. coli called O157:H7. The tested package of 93 percent lean ground beef is marked with an “Establishment” (EST) number of 965, representing the plant where the meat was processed, and a “use or freeze by date” of 1/11/2022. (See the product label below.)

At this time, there is no recall of this ground beef, and no illnesses have been linked to the product. But CR’s food-safety experts warn consumers who might have purchased Kroger-branded 93 percent lean ground beef from any Kroger-owned grocery store to check their packages and to throw away the product if it contains that establishment number and “use or freeze by” date. Those stores include Fred Meyer, Harris Teeter, Ralphs, Dillons, and several other supermarkets. (See a complete list of Kroger-owned grocery stores.) Consumers also should not buy ground beef with those markings from any of those stores.

Research – Prevalence and patterns of fecal shedding of Shiga toxin–producing Escherichia coli by cattle at a commercial feedlot in South Africa

Wiley Online

Healthy colonized cattle are the major reservoir of Shiga toxin–producing Escherichia coli (STEC) and play a key role in the entry point of the pathogen into the beef chain. Excretion rates and the concentration of the pathogen in feces influence the epidemiology and transmission of the pathogen within herds and to humans. This study evaluated the prevalence and dynamics of fecal shedding of STEC by cattle in a commercial feedlot in Gauteng, South Africa. An initial cross-sectional survey was conducted; fecal samples were obtained from 106 randomly selected weaned beef calves on arrival at the feedlot using polymerase chain reaction (PCR) to screen by detecting stx1 and stx2 genes. Subsequently, a longitudinal study was conducted, and 15 STEC-positive and 11 STEC-negative cattle were sampled monthly and followed to slaughter. STEC O157 and non-O157 were enumerated in samples using commercial chromogenic agar. Initial prevalence of STEC shedding was 27% (29/106; 95% CI [19, 37%]). All 26 cattle shed STEC intermittently or continuously during the study period, all except one were super-shedders (≥4 log10 CFU/g) at one or more samplings, and 19 (73%) were persistent or intermittent super-shedders. Of the 38 STEC isolates recovered, 15 (39%) were serotypeable, representing 11 non-O157 serogroups, including O101, O168, O178, and O68. The most frequent virulence combination profile was stx1 + eaeA + ehxA (n = 12; 32%). This study confirms the occurrence and variability of STEC super-shedding in feedlot cattle and highlights that super-shedding is not limited to STEC O157. It also shows their public health significance.

Centre for Food Safety

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department today (December 20) urged the public not to consume three kinds of cheese imported from France due to possible contamination with Shiga toxin-producing Escherichia coli (STEC). The trade should stop using or selling the affected batches of products immediately if they possess them.

Details of the products are as follows:

Product name:  (1) FRERES MARCHAND – CANTAL ENTRE DEUX AOP
(2) TRADITIONAL SELECTION 1KG – 4 CHEESES
(3) TRADITIONAL SELECTION 2KG – 6 CHEESES
Brand: Les Frères Marchand
Place of origin: France
Importer: Classic Fine Foods (Hong Kong) Limited
Lot: LOT 21-45

A spokesman for the CFS said, “The CFS received a notification from the Rapid Alert System for Food and Feed (RASFF) of the European Commission that the above-mentioned products might have been contaminated with STEC and are being recalled. According to the information provided by the RASFF, the affected batches of products have been imported into Hong Kong. Upon learning of the incident, the CFS immediately contacted the local importer concerned for follow-up.”

A preliminary investigation found that the importer, Classic Fine Foods (Hong Kong) Limited, had imported some of the affected batches of products into Hong Kong. The importer concerned has initiated a recall according to the CFS’ instructions. Enquiries about the recall can be made to the hotlines at 2612 2066 during office hours.

“People will contract STEC-causing gastro-intestinal disease through consumption of contaminated water or undercooked and contaminated foods. Intestinal bleeding and serious complications such as hemolytic uraemic syndrome may also develop in some people,” the spokesman said.

The spokesman urged consumers not to consume the affected batches of the products if they have bought any. The trade should also stop using or selling the affected batches of products concerned immediately if they possess them.

The CFS will alert the trade to the incident, continue to follow up and take appropriate action. An investigation is ongoing.
