Veriflow Campylobacter. Performance tested method 101201.


Veriflow Campylobacter is a molecular based assay for the presumptive and qualitative detection of the most common occurring foodborne Campylobacter species: C. jejuni and C. coli. The assay utilizes a PCR detection method coupled with a rapid, visual, flow-based assay that develops in 3 min post PCR amplification and requires only 24 h of non-specialized enrichment for maximum sensitivity. The Veriflow Campylobacter system eliminates the need for microaerobic chambers, gel electrophoresis or fluorophore based detection of target amplification, and does not require complex data analysis. This Performance Tested Method validation study demonstrated the ability of the Veriflow method to detect naturally occurring Campylobacterfrom chicken carcass rinsates. In the reference comparison study, Chi-square and probability of detection analyses of two unpaired studies indicated that there was no significant difference between the Veriflow Campylobacter method and the U.S. Department of Agriculture (USDA)/Food Safety and Inspection Service (FSIS) reference method. There was no indication of false positive or false negative detection in the reference comparison study, and all 50 C. jejuni and C. coli strains were detected, while 35 nonspecific organisms were undetected in the exclusivity/ inclusivity study. The study results show that Veriflow Campylobacter is a sensitive, selective and robust assay for the detection of C. jejuni and C. coli in chicken carcass rinsates.
