The interest in animal speciation in meat products is based on:
Religious requirements (halal and kosher)
Religiously motivated inspections, particularly of pork in meat products or processed foods, do not include any technical threshold values. This means that purely qualitative and particularly sensitive tests are required especially for detecting the presence of pork. Real-time PCR is a method of choice. The effective sensitivity of applied real-time PCR tests is based on the existence of intact DNA, making sensitive detection in heavily processed foods like gelatine difficult.
The varying prices and availability of meat products from different animal species provide opportunities for the incorrect declaration of meat components, both from a quality and quantity point of view. Such product adulterations can be detected highly specifically and quantified relatively by means of a real-time PCR (providing percentage values of the respective animal species in relation to the total quantity of meat). The products for product alterations can be found here.
