Study finds new data on E. coli shedding in dairy cattle

A collaborative Michigan State University study involving microbiologists, epidemiologists, animal scientists, veterinarians, graduate students, undergraduates and farmers could lead to better prevention practices to limit dangerous Escherichia coli (E. coli) bacteria transmissions.

Published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology, the study found that dairy cattle under stress from […]

FSIS issues new guidelines for marking sample sources during STEC testing

E. coli

Inspectors will soon see a change in the way they note the source of samples taken during routine Shiga toxin-producing E. coli (STEC) testing.

The new measures apply to samples taken during STEC verification testing that then are added to the Public Health Information System (PHIS). Sources will be marked as either […]

New beef rules to take effect in two months

Food companies that sell raw, nonintact beef and ready-to-eat meat and poultry products soon will be required to hold the products until they test negative for adulterants.

Study: E. coli lives longer in certain soils

E. coli

E. coli O157:H7, one of the most common illness-causing strains of E. coli, can survive in the soil of California’s Salinas Valley for about 30 days – roughly ten days more than it does in Imperial Valley, Calif. or Yuma, Ariz. Researchers attribute the longer lifespan to lower salinity in irrigation water […]

Report: Despite food safety reforms, illnesses continue to rise

Almost 2,000 Americans fell ill from foods related to recalls in the past year, despite the passage of legislation to make food safer, according to a report from the U.S. Public Interest Group (U.S. PIRG).

Contaminated food – not just those linked to recalls – sickens approximately 48 million Americans annually and costs more than […]

FSIS aims to change E. coli O157:H7 testing program for beef trim

E. coli

E. coli O157:H7 testing may soon be more risk-based, according to a notice posted in the Federal Register.

The USDA’s Food Safety and Inspection Service (FSIS) announced it is seeking comments on a redesign of its E. coli O157:H7 verification system to make it more risk-based while also allowing the agency to […]

Study: Toxin-producing E. coli strain could contribute to cancer

E. coli

New findings suggest toxin-producing microbes in the gut could lead to cancer, according to research published in Science.

Mice with inflammatory bowel disease have more of these toxin-producing bacteria, which could lead to certain cancers. Humans with the same cancer also have been found to have these bacteria.

The bacteria at the […]
