Applied Food Diagnostics Announces First Journalist’s First Total QC Diagnostic Line for Food Pathogens

BLOOMSBURG, Pennsylvania., July 20, 2021 / PRNewswire / – Applied Food Diagnostics, Inc., the world’s most innovative microbiology laboratory solutions company, is pleased to announce a new line of qPCR diagnostic products. AFD’s revolutionary line of Total QC-qPCR test kits simultaneously detects target food pathogens as well as a reporter-tagged quality control strain, such as green fluorescent protein.

Many food pathogen laboratories currently use positive quality control strains labeled with green fluorescent protein (GFP). These GFP strains are processed along with routine samples for process verification. This verification activity has been and will always be a potential source of laboratory cross-contamination. When a molecular screening test is positive, the normal procedure is to culture from the enrichment and wait an additional 24-72 hours to determine if the positive result is the result of QC contamination by examination. visual under UV light. This process is inherently problematic because different aliquots are used. The Total QC-qPCR line immediately distinguishes a positive quality control strain labeled with green fluorescent protein (GFP) while identifying a positive native wild-type strain on the same aliquot during the initial rapid screening procedure.

The Total QC-qPCR line is valid for all major food pathogens including, but not limited to; E. coli O157: H7, production of Shiga Toxin E. coli, Salmonella, Listeria spp., Listeria monocytogenes, Cronobacter sakazakii, and Vibrio cholerae.

“Adding the GFP target saves labs time, manpower, and unnecessary investigation costs. Food producers no longer need to wait an extra 2-3 days to find out if there has been a lab error; Our food systems deserve better. The results of our Total QC-qPCR range offer a higher level of certainty than any other diagnostic on the market ”, states Nathan Libbey, vice president of sales and marketing.
