DNA Chip Tech for Identifying Animal Species in Food

Following the horsemeat crisis in 2013, identification of animal species in food products has become a major concern for the feed and food industry in Europe. Existing analytical methods for the detection of single species are no longer sufficient to meet the current supply chain requirements, such as verifying that product composition not only complies with relevant regulations, but is also entirely consistent with the claims on the label, and ensuring the absence of undesired species in the product (e.g. horsemeat in beef, or ruminants in animal feed).

The molecular biology testing unit of Eurofins’ flagship laboratory in Nantes has developed an innovative DNA chip testing method to expand the scope of analysis to multiple species in different food and feed matrices. Using mitochondrial DNA targets, the chip technology enables sensitive and reliable detection at low thresholds (0.1%) with a short turnaround time (5 working days from sample reception). With this fully-accredited test, specific and cost-effective detection of a large panel of species is now possible. The modular concept of the technology allows the identification of up to 21 meat species, according to customer needs, with only one test. The method has been specifically developed for meat and complex and/or processed food, as well as animal feed and pet food. With this new qualitative test, Eurofins provides unparalleled testing services for a wide range of species identification, including “species-specific” PCR to detect one particular species and other semi-quantitative tests to determine the proportions of the species contained in the product.

The new meat speciation test is another illustration of Eurofins’ capability to leverage its Group-wide competencies to deliver the most innovative analytical solutions for its clients, and maintain its leading position as the leading reference laboratory group for food and feed testing worldwide.
