FSIS is revising its detection methods in the FSIS Microbiology Laboratory Guidebook, Detection and Isolation of Non-O157 Shiga-Toxin Producing Escherichia coli strains (STEC) from Meat Products, to expand laboratory testing t detect additional strains of the six targeted serogroups.

The most significant changes will be the modification of the media used to grow the bacteria and a new set of primers and probes, according to the North American Meat Processors Association.
The effective date for the new procedures will be early November.

Preparation instructions will be available here.
