BELLEVUE, Wash. – BioControl Systems has received additional “No Objection” letters from the United States Department of Agriculture Food Safety Inspection Service (USDA FSIS) for its Assurance GDS methods for the detection of non-O157 STEC.
Four BioControl test methods for Top STEC have now been issued letters of No Objection, the company said.
Assurance GDS combines advancements in immunomagnetic separation (IMS), molecular technology, and food microbiology to provide four new methods for the detection of the major non-O157 serotypes of Shiga Toxigenic E. coli (STEC) O26, O45, O103, O111, O121, O145 and E. coli O157:H7, BioControl said. “No Objection” letters were received for the following methods: Assurance GDS Top 7 STEC MPX, Assurance GDS Top 6 STEC MPX, Assurance GDS Top 7 STEC (eae), and Assurance GDS Top 6 STEC (eae).
The Assurance GDS pathogen detection methods include a proprietary IMS-based sample preparation procedure specifically targeting either the top 6 or 7 O serogroups followed by PCR analysis for the detection of the eae and stx1 and stx2 genes. This approach satisfies the USDA criteria for detection of STEC. The Assurance GDS methodology targets the STEC genetic sequences contained in the specific serogroups of concern and minimizes false positives from other O serogroups while eliminating the need for additional analysis.
