Identification of meat species in pet foods using a real-time polymerase chain reaction (PCR) assay

Product mislabeling, adulteration, and substitution are increasing concerns in highly processed foods, including pet foods. Although regulations exist for pet foods, there is currently a lack of information on the prevalence of pet food mislabeling. The objective of this study was to perform a market survey of pet foods and pet treats marketed for domestic canines and felines to identify meat s...

Identification of Meat Species by Polymerase Chain Reaction ( PCR ) Technique

The origin of horse, dog, cat, bovine, sheep, porcine, and goat meat was determined by the polymerase chain reaction (PCR) technique, using species-specific primers. Test mixtures of meat were prepared by adding 5%, 2.5%, 1%, 0.5%, and 0.1% levels of pork, horse, cat, or dog meat to beef, sheep, and goat meat. Samples taken from those combinations were analyzed by PCR for species determination....

Conventional multiplex polymerase chain reaction ( PCR ) versus real - time PCR for species - specific meat

Simple and reliable conventional multiplex-polymerase chain reaction (multiplex-PCR) as well as real-time PCR approaches for the partial-length cytochrome b or cyt b gene of mitochondrial DNA (mtDNA) were compared to identify seven animal species for the authenticity of low non Halal (pig, dog, cat and donkey) and high value Halal (cattle, sheep and goat) meats. Either analysis indicated the su...

Development of a Quantitative Real-Time Polymerase Chain Reaction (RT- PCR) Assay for Plant Species

In order to facilitate optimal plant DNA quantitation and identification, an assay has been developed that uses generic plant PCR primers that amplify a region in the chloroplast genome of plant samples. The assay uses the SYBR green detection dye to detect the PCR product with a universal PCR primer set to the large subunit of ribulose bisphosphate carboxylase, rbcL, but can be used with any o...
