Take Your EHEC Testing to a New Level! Be Assured of Compliance with USDA FSIS Regulations

Secondary Assay for Greater Confidence

The Assurance® GDS EHEC ID E. coli O157:H7 Tq 4-channel multiplex assay is designed to follow the Assurance® GDS E. coli O157:H7 Tq assay. Potential positive enriched samples from the first assay can be genetically confirmed as containing E. coli O157:H7 per the revised USDA FSIS definition (including stx1, stx2, and fliC:H7 genes).

Additionally, the GDS EHEC ID assay can also be used to confirm isolated colonies from presumptive positive samples for E. coli O157:H7 as part of the cultural confirmation.

Results are available the same day when using the complete Assurance® GDS EHEC method, saving precious time for your perishable food samples.

Key Features:
  • 3 levels of specificity: PickPen® IMS, primers, and gene probes
  • AOAC® PTM validated composite 375 g sample sizes of raw ground beef, raw beef trim, frozen finely textured beef and carcass cloths
  • Single harmonized proprietary mEHEC® enrichment
  • Clear results available same day - no interpretation required
