Abstract:
Traceability of meat has become a very important aspect of quality assurance of food. DNA analyses could be used for identification and verification of farm animals and animal derived products. A prerequisite is the collection of qualified samples from entire populations of production animals or from regionally or specially characterised animal populations. The expenditure for conventional carrying out collection, preservation, cataloguing, and storage would be enormous. Therefore we have developed a simple, reliable, and inexpensive method for the collection using the ear tagging process and for preservation of samples at room temperature. A similar collection technology can also be used for sampling of carcasses, meat and meat products. Isolation of DNA from these tissue samples can be preformed using a new single step technology. For identifying individuals microsatellites and single nucleotide polymorphisms are analysed. Comparison of DNA fingerprints or SNP signatures allows to traceback samples collected from products to the animals they are coming from. If the system will be established on a nationwide basis the total costs would be less than 0.05 EUR per kilogram meat sold.
