Genetic characterization of Escherichia coli in meat that harbor locus of heat resistance

The presence of locus of heat resistance is a common way of screening heat resistance in E.coli, however harboring LHR does not always confer extreme heat resistance suggesting other genetic components may play a role in heat resistance. WGS was performed to determine genetic determinants in E.coli for different levels of heat resistance and determine the evolution regarding the emergence of heat resistant strains of E.coli in a meat plant setting.
