USA – Outbreak Investigation of E. coli Linked to Ground Bison from Northfork Bison Distributions, July 2019 – E.coli O121 – E.coli O103

FDA

July 16, 2019

The U.S. Food and Drug Administration (FDA), along with the Centers for Disease Control and Prevention (CDC), state and local partners in the U.S., and with the support of the Canadian Food Inspection Agency (CFIA), are investigating a multistate outbreak of E. coli O121 and E. coli O103 illnesses likely linked to ground bison supplied by Northfork Bison Distributions Inc. of Saint-Leonard, Québec, Canada.

The FDA and CDC analyzed traceback and epidemiological information to determine that ground bison supplied by Northfork Bison Distributions Inc. is the likely cause of the illnesses.

FDA regulates bison meat because the authority is not assigned specifically to the United States Department of Agriculture’s (USDA) Food Safety and Inspection Service (FSIS) in the Federal Meat Inspection Act (FMIA).

Recommendation

Buffalo Burger Canadian Bison Meat

Distributors, retailers and restaurants should not distribute, use or serve ground bison (including bison burgers) recalled by Northfork Bison Distributions Inc.

As of July 16, 2019, Northfork Bison Distributions Inc. is voluntarily recalling its ground bison, referred to as Bison Ground, and its ground bison patties, referred to as Bison Burgers and/or Buffalo Burgers, produced between February 22, 2019, and April 30, 2019.

Consumers should not eat products prepared using recalled ground bison (including bison burgers) sold under the Northfork Bison label including Bison Burgers sold to retailers in 4 x 4-ounce packages with expiration dates through October 8, 2020.

Northfork Bison Distributions Inc. has been quick to initiate a voluntary recall and has been forthcoming with information to aid in the investigation. The investigation is ongoing and updates will be provided when available.

USA – Winnebago County Illinois Health Department monitoring STEC E. coli Mystery

Food Poison Journal

The Winnebago County Illinois Health Department has confirmed three cases of Shiga toxin‐producing E. coli (STEC) in the county.

The patients experienced diarrhea beginning May 31. The cause of the illness has not yet been determined, the department announced Friday evening.

The following are symptoms of E. coli and may be seen with or without a fever: abdominal cramps, watery or bloody diarrhea and vomiting. Residents are urged to contact a health care provider if they experienced symptoms on or after May 21.

Abstract

Escherichia coli O157:H7 (E coli O157:H7) is a highly virulent bacterial strain that is present in food, and as few as 10 cells can cause severe diseases. Rapid and sensitive bacterial detection is urgently required. In this study, we report a flow cytometry (FCM)‐based method for detecting E coli O157:H7 at the single‐cell level. Single E coli O157:H7 cells were obtained by a flow cytometric cell sorter and then artificially added to milk. Next, using BHI for 6.5 hr of enrichment, isolation of target cells, and dual staining, this method could be applied to detect single viable E coli O157:H7 cells in 25 mL of milk. The time to results (TTR) of the FCM‐based method was 7 hr.

Practical applications

The plate‐based method is the currently recommended method for detection of single E coli O157:H7 cells in milk because of the ease of operation. However, this method is time‐consuming, requiring enrichment of the target organism to attain quantifiable levels. Accordingly, rapid detection of microorganisms in milk would be of great benefit to public health. Flow cytometry (FCM) is a sensitive technique that can be used to rapidly analyze foodborne pathogens. Unfortunately, little attention has been paid to single‐cell detection in milk. This study provides a rapid method for detection of single viable E coliO157:H7 cells in milk. This method has the potential to provide effective protection against E coli O157:H7 contamination and is required for rapid detection of microorganisms in dairy products.
