On June 4, food regulators began screening beef for six more strains of E. coli beyond the already-monitored E. coli O157:H7. Since that time, 110 samples of beef trim have been tested for non-O157 E. coli; 3 were found to be carrying these bacteria.
USDA’s Food Safety and Inspection Service published these initial findings in a results chart this week. The three positive test results represented three different strains of E. coli: O45, O103 and O145, each of which was found once. No samples have yet tested positive for the other three strains: O26, O111 and O121.
