Three qPCR assays targeting the locus of heat resistance to identify heat resistant clinical Escherichia coli isolates are described. Of 613 isolates, 3 (0.5%) possessed the locus. The assays are a rapid, highly sensitive and specific alternative to screening by heat shock and can be used in food safety surveillance.
