To protect the quality and safety of consumable products, the food industry relies on the use of high-quality reference materials when testing products, raw ingredients, and associated equipment for microbial contamination. To support this need, ATCC has developed reporter-labeled control strains representing the Shiga toxin-producing Escherichia coli serogroups most frequently associated with foodborne illness.

These GFP-labeled strains make it easier for food testing laboratories* to ensure the safety of consumable goods by providing an efficient and reliable method to distinguish control strain cross-contamination from true contamination.

Each strain has been authenticated through genotypic, phenotypic, and functional analyses to ensure strain authentication, serotype, and the presence of select virulence genes. Further, they have been thoroughly examined for reporter expression, vector stability, compatibility with detection technologies, growth rate, and fitness trends.
