qPCR Testing for Food Pathogens

One of the best developed and successful applications of Quantitave PCR (qPCR) is the detection and quantification of pathogens, including viruses, bacteria and eukaryotic microorganisms, as well as a number of parasites. It has been used to monitor the presence of antibiotic resistance genes that might be transferred to pathogenic or commensal bacteria in cheese and other food-related scenarios. Other applications include the detection of food ingredients, ingredient fraud, monitoring of unintended contamination of special foods (e.g., gluten-free foods), toxin-encoding genes to detect genetically modified organisms, allergens and certain non-pathogenic spoilage microorganisms. This testing is extremely detailed and specific. It has truly aided many in the science and food industry to improve and understand the products we purchase on a daily basis.

Quantitave PCR (qPCR) is a proven method for pathogen detection and has been applied successfully to a wide range of foodborne pathogens, including Salmonella, Listeria monocytogenes, and E. coli O157:H7. qPCR tests for food pathogens amplify and detect a DNA target sequence that is specific to the organism under investigation. In this way, qPCR can detect pathogens quickly, simply, and with outstanding sensitivity and specificity.
