Research -Shiga Toxin–Producing Escherichia coli O157:H7 Illness Outbreak Associated with Untreated, Pressurized, Municipal Irrigation Water — Utah, 2023

CDC

During July–September 2023, an outbreak of Shiga toxin–producing Escherichia coli O157:H7 illness among children in city A, Utah, caused 13 confirmed illnesses; seven patients were hospitalized, including two with hemolytic uremic syndrome. Local, state, and federal public health partners investigating the outbreak linked the illnesses to untreated, pressurized, municipal irrigation water (UPMIW) exposure in city A; 12 of 13 ill children reported playing in or drinking UPMIW. Clinical isolates were genetically highly related to one another and to environmental isolates from multiple locations within city A’s UPMIW system. Microbial source tracking, a method to indicate possible contamination sources, identified birds and ruminants as potential sources of fecal contamination of UPMIW. Public health and city A officials issued multiple press releases regarding the outbreak reminding residents that UPMIW is not intended for drinking or recreation. Public education and UPMIW management and operations interventions, including assessing and mitigating potential contamination sources, covering UPMIW sources and reservoirs, indicating UPMIW lines and spigots with a designated color, and providing conspicuous signage to communicate risk and intended use might help prevent future UPMIW-associated illnesses.

Research – Biological Control of Escherichia coli O157:H7 in Dairy Manure-Based Compost Using Competitive Exclusion Microorganisms

MDPI

Abstract

Background: Animal manure-based compost is a valuable organic fertilizer and biological soil amendment. To ensure the microbiological safety of compost products, the effectiveness of competitive exclusion microorganisms (CE) in reducing Escherichia coli O157:H7 in dairy manure-based compost was evaluated. Methods: A cocktail of E. coli O157:H7 strains were inoculated into dairy compost along with CE strains isolated from compost, and the reduction in E. coli O157:H7 by CE was determined in compost with 20%, 30%, and 40% moisture levels at 22 °C and 30 °C under laboratory conditions, as well as in fall, winter, and summer seasons under greenhouse settings. Results: Under lab conditions, CE addition resulted in 1.1–3.36 log reductions in E. coli O157:H7 in compost, with enhanced pathogen reduction by higher moisture and lower temperature. In the greenhouse, >99% of the E. coli O157:H7 population in compost with ≥30% moisture due to cross-contamination can be effectively inactivated by CE within 2 days during colder seasons. However, it took ≥8 days to achieve the same level of reduction for heat-adapted E. coli O157:H7 cells. Conclusions: Our results demonstrated that the competitive exclusion of microorganisms can be an effective tool for controlling foodborne pathogens in compost and reducing the potential for soil and crop contamination.

FSIS USDA

Cargill Meat Solutions, a Hazleton, Pa., establishment, is recalling approximately 16,243 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 raw ground beef items were produced on April 26-27, 2024. The following products are subject to recall [view labels]:

  • 2.25-lbs. plastic-wrapped trays containing “93% LEAN 7% FAT ALL NATURAL LEAN GROUND BEEF” with lot code 117 and establishment number “EST. 86P” printed on the back of the label.
  • 1.33-lbs. plastic-wrapped trays containing four “PRIME RIB BEEF STEAK BURGERS PATTIES” with lot code 118 and establishment number “EST. 86P” printed on the back of the label.
  • 2.25-lbs. plastic-wrapped trays containing “85% LEAN 15% FAT ALL NATURAL ANGUS PREMIUM GROUND BEEF” with lot code 117 and establishment number “EST. 86P” printed on the back of the label.
  • 2.25-lbs. plastic-wrapped trays containing “80% LEAN 20% FAT ALL NATURAL GROUND BEEF CHUCK” with lot code 118 and establishment number “EST. 86P” printed on the back of the label.
  • 1.33-lbs. plastic-wrapped trays containing four “80% LEAN 20% FAT ALL NATURAL GROUND BEEF CHUCK PATTIES” with lot code 118 and establishment number “EST. 86P” printed on the back of the label.
  • 1.33-lbs. plastic-wrapped trays containing four “90% LEAN 10% FAT ALL NATURAL GROUND BEEF SIRLOIN PATTIES” with lot code 118 and establishment number “EST. 86P” printed on the back of the label.

The products subject to recall all bear the USDA mark of inspection on the front of the product label, and establishment number “EST. 86P” printed on the back of the product label. These items were shipped to Walmart retail locations nationwide.

The establishment reported the issue to FSIS after they identified that previously segregated product had been inadvertently utilized in the production of ground beef.

There have been no confirmed reports of adverse reactions due to consumption of these products. 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 with questions about the recall can contact Cargill Meat Solutions at 1-844-419-1574. Members of the media with questions about the recall can contact Chuck Miller, Senior Communications Manager, Cargill Meat Solutions at 612-430-2882 or media@cargill.com.

Consumers with food safety questions can call the toll-free USDA Meat and Poultry Hotline at 888-MPHotline (888-674-6854) or send a question via email to MPHotline@usda.gov.

USA – Gibson Farms Voluntarily Recalls Organic Light Halves and Pieces Shelled Walnuts Because of Possible Health Risk – E.coli O157

FDA

Gibson Farms Organic Light Halves and Pieces shelled walnuts, Bulk Boxes, Net Wt. 25 lbs

Company Announcement

On 04/26/2024, Gibson Farms recalled Organic Light Halves and Pieces shelled walnuts because Gibson Farms received information that they may have the potential to be contaminated with E. Coli 0157:H7. E. coli O157:H7 causes a diarrheal illness often with bloody stools. Although most healthy adults can recover completely within a week, some people can develop a form of kidney failure called Hemolytic Uremic Syndrome (HUS). HUS is most likely to occur in young children and the elderly. The condition can lead to serious kidney damage and even death.

The Organic Light Halves and Pieces shelled walnuts were sold to distributors located in CA and WA. Gibsons Farms Organic Light Halves and Pieces shelled walnuts were sold in bulk boxes in Net Wt. 25 lbs quantities and can be identified by lot 3325-043 & 3341-501 with expiration dates 5/21/25 & 6/7/25.

Gibson Farms, Inc. has voluntarily recalled the product(s) after being notified by the CDC of 12 recorded illnesses allegedly linked to the consumption of organic halves and pieces shelled walnuts. A full investigation is currently under way to determine the potential source of the contamination.

Gibson Farms requests consignees to hold and discontinue selling their existing stock of lot 3325-043 and lot 3341-501 and return any remaining inventory of the recalled products to our local warehouse Gibson Farms 1190 Buena Vista Rd Hollister Ca 95023. If you have distributed or sold this product to other retailers, please notify your clients as to the status of this product.

Outbreak Investigation of E. coli O157:H7: Bulk Organic Walnuts (April 2024) | FDA

UK – Shiga toxin-producing Escherichia coli (STEC) data: 2020 – Updated 26/04/2024

Gov UK

Main points

A total of 402 confirmed cases of Shiga toxin-producing Escherichia coli (STEC) O157 were reported in England and Wales in 2020.

The lowest incidence of STEC O157 was in the London region (0.29 per 100,000 population) and the highest in the South West region (1.04 per 100,000 population).

Children aged 5 to 9 years had the highest incidence of infection (1.50 per 100,000 population, 95% confidence interval (CI) 1.12 to 1.96).

One-third of confirmed STEC O157 cases in England were hospitalised and 3% were reported to have developed Haemolytic Uraemic Syndrome (HUS).

A further 286 specimens in England and 41 in Wales were positive for Shiga toxins (Stx) genes on polymerase chain reaction (PCR) at the Gastrointestinal Bacteria Reference Unit (GBRU) but an organism was not cultured.

The most commonly isolated non-O157 STEC serogroup was STEC O26 (England: n=103 out of 553, 19%; and Wales: n=26 out of 268, 15%).

Three outbreaks of STEC involving 63 cases in England were investigated in 2020.

USA – FSIS Issues Public Health Alert for Ground Beef Products Due to Possible E. Coli O157:H7 Contamination

FSIS USDA

The U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) is issuing a public health alert for ground beef products that may be contaminated with E. coli O157:H7. FSIS is issuing this public health alert to ensure that consumers are aware that these products should not be consumed. A recall was not requested because the products are no longer available for purchase.

The raw ground beef items were produced on March 28, 2024. The products have a “Use/Freeze by” date of April 22, 2024, and packaging date of “032824.” The list of products that are subject to the public health alert can be found here. The labels for these products can be found on the FSIS website [view labels].

The products subject to the public health alert bear establishment number “EST. 960A” inside the USDA mark of inspection. These items were shipped to food service institutions and retail locations nationwide.

The problem was discovered by the establishment while conducting an inventory of product that was on hold because it was found positive for E. coli O157:H7. The company notified FSIS that they inadvertently used a portion of the contaminated beef to produce ground beef products that they subsequently shipped into commerce.

There have been no confirmed reports of illness due to consumption of these products. Anyone concerned about an illness should contact a healthcare provider.
