Shiga toxin—producing Escherichia coli (STEC) are important human pathogens, and
attention to non-O157 serogroups has increased in recent years. Although cattle are …

Cattle are the main reservoirs for Shiga toxin-producing Escherichia coli (STEC) strains. E.
coli O26, O45, O103, O111, O121, O145, and O157 are among the STEC serogroups that …

Shiga toxin-producing Escherichia coli (STEC) are a public health concern. Bacterial culture
techniques commonly used to detect E. coli O157: H7 will not detect other STEC serotypes …

Shiga toxin–producing Escherichia coli (STEC) produce toxins that have been associated
with several human illnesses. E. coli O157: H7 is the most well-studied STEC and was first …

While efforts to control foodborne illness associated with the Shiga toxin–producing
Escherichia coli (E. coli) O157 through processes and procedures implemented at harvest …

Escherichia coli O157 and six non-O157 Shiga toxin–producing E. coli (STEC) serotypes
(O26, O45, O103, O111, O121, and O145, colloquially referred to as the “big 6”) have been …

Escherichia coli O157: H7 and the big six non-O157 E. coli serogroups (O26, O45, O103,
O111, O121, and O145) have been declared adulterants in meat. Cattle and other ruminants …

The study objectives were to determine the prevalence and serotypes of non-O157 Shiga
toxin-producing Escherichia coli (STEC) in pens of feedlot cattle and on corresponding beef …

Abstract The United States Department of Agriculture Food Safety and Inspection Service
has declared seven Shiga toxin–producing Escherichia coli (STEC) serogroups (O26, O45 …

The objective of the current study was to determine the incidence of contamination by the top
7 Shiga toxin–producing Escherichia coli (STEC) O-groups, responsible for the majority of E …
