Food adulteration

Increased awareness since the horsemeat scandal

Since the horsemeat scandal, awareness of food adulteration and food fraud has significantly increased. Consumers and regulatory bodies are now more vigilant about ensuring the authenticity of food products.

Opportunities for food adulteration

The varying prices and availability of food products from different origins create opportunities for incorrect declaration of food components. Adulteration can occur both in terms of quality and quantity, with cheaper or readily available ingredients being mislabeled as more expensive or desirable ones. For example, horsemeat may be mislabeled as beef. Such product adulterations can be detected with high specificity and quantified relatively using advanced testing methods like real-time PCR, which can provide percentage values of the respective animal species in relation to the total quantity of meat.

Religious requirements and animal speciation

Interest in animal speciation in meat products also stems from religious requirements, such as halal and kosher certifications. Religiously motivated inspections, particularly for detecting pork in meat products or processed foods, do not allow for any technical threshold values, requiring purely qualitative and highly sensitive tests. Real-time PCR is often used for this purpose due to its high sensitivity, though its effectiveness depends on the presence of intact DNA, which can be challenging to detect in heavily processed foods like gelatin.

Adulteration beyond meat products

Food fraud is not limited to meat products; it is also widespread in fish and dairy products. Each category presents unique challenges and requires specific detection methods to ensure product authenticity and consumer trust.
