Testing of Raw Ground Beef Component (RGBC) Samples for E. coli O157:H7 and non-O157 Shiga toxin-producing E. coli (STEC): Year-to-Date Totals
|
Table 1 presents the results from analysis of raw ground beef component samples for non-O157 STECs. Results are from FSIS routine and follow-up sampling programs. Table 2 presents the results from analysis of raw ground beef component samples for both E. coli O157:H7 and for the non-O157 STECs by each non-O157 STEC serogroup. Information is based upon data in the FSIS electronic data system as of September 22, 2013.

1 Results are posted according to the sample analysis completion date. 2 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 and not 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, as well as E. coli O157:H7. 3 Positives 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 tables. This is due to the possibility that one sample may be positive for multiple serogroups. View the information in Table 2 by Source (beef, veal, etc.) |
