Invisible Sentinel’s platform for detecting shiga toxin producing E. coli (STEC) has been certified by the Association of Analytical Communities (AOAC).

Veriflow STEC uses proprietary DNA Signature Capture Technology and SSMA technology (Single Signal for Multiple Analytes) to detect organisms that encode for Stx 1 and/or 2 expression and eae expression.

It has a time to result of less than 18 hours.

Pathogenicity of STEC is linked to virulence factors that include shiga toxins (Stx) 1 and 2 as well as eae which mediates adherence to the intestinal wall.

E. coli that has one or both shiga toxins in addition to EAE are the most likely to cause foodborne illness.

Invisible Sentinel has AOAC approvals for six assays designed to protect against illness due to foodborne pathogens including Listeria species, Listeria monocytogenes, Salmonella species, E. coli O157:H7 and Campylobacter species.

The firm also has detection tools for spoilage organisms in wine, beer and juice.
