5 Source information for raw ground beef products sampled at retail is not collected.
6 Percent positive: The percent positives shown do not reflect national prevalence for E. coli O157:H7 in raw ground beef/veal or raw ground beef/veal components because the risk-based algorithm used to schedule the sampling is not random and therefore is not representative of the population.

2013 Raw Ground Beef or Veal Components Sampling for total Shiga toxin-producing E. coli (STEC) (Table 2)

FSIS determined the percent positives for STECs for the following sampling programs and product classes in CY2013:

  • Routine verification testing for domestic raw ground beef or veal components was 0.46% (25/5,387).
  • Verification testing for imported raw ground beef or veal components was 0.3% (3/1,013).

The top three O groups represented in the positive results were O157:H7, O103, and O26.

1 FSIS test results for the 6 target non-O157 STECs appear for only samples of beef manufacturing trimmings from cattle slaughtered on-site on or after June 4, 2012. At this time, only beef manufacturing trimmings (defined as trimmings that are intended for use in raw ground beef or beef patty products produced at the slaughter plant) and not other components (such as bench trim, or other components of ground beef such as cheek meat and head meat) are eligible for testing for non-O157 STEC.

Definitions, composition, and description of Raw Ground Beef Components sampling programs
4 Serotypes reported in this table are adulterant STECs. FSIS considers E. coli O157:H7 and the top six non-O157 O groups (O26, O45, O103, O111, O121, and O145), that also cotain the stx and eae genes, as adulterants.
5
Definitions of sampling categories
6 Percent Positive: The percent positives shown do not reflect national prevalence for E. coli O157:H7 in raw ground beef/veal or raw ground beef/veal components because the risk-based algorithm used to schedule the sampling is not random and therefore is not representative of the population.
7
(Number positive/number analyzed). Number Positive and Percent Positives on this table include all serogroups tested and do not reflect the total number of individual positive samples on the Individual Positives and the non-O157 STEC YTD or CY 2012 tables. This is because one sample may be positive for multiple serogroups.
8 Mixed source is composed of both beef and veal products.
9 Incomplete data recorded.
