Research - Using electronic identification (EID) and molecular markers (DNA) for improving the traceability of meat

Background

Traceability is sensitive point for consumers. Despite this, methods for tracing meat are poorly developed. With this aim, a double system based on electronic identification (BID) and DNA profiling for tracing animals and meat, according to EC regulations, is proposed. Improving knowledge of EID and overcoming limiting factors in the use of bolus (ruminants) and injectable (pig) transponders, will be attempted. We will develop and test a competitive new reader, and automatic data transfer (animal to meat) and recovery of transponders in the abattoir will also be studied. For DNA profiling, selection of markers and comparison of sampling methods will be performed. Finally the evaluation of the implementation for tracing and quality monitoring of beef and pork meats, including the management of a data base and a cost-benefit analysis, will be made.

Objectives

Primary objective: the development of a reliable system for the traceability of livestock and meat based on the joint use of electronic identification (EID) and molecular rnarkers (DNA). The BID will provide a real time tagging and tracing-back methodology for on farm use and administrative purposes until slaughtering; the DNA profile will be used as an unchangeable method to audit the tracing-back of the identity of animals, carcasses and meat cuts in the whole meat industry process, at reasonable cost and response time. Further objective: the implementation and evaluation of the double system (EID+DNA) for the tracing and quality monitoring of beef ('red' and 'pink' meat) and park ('white pig' fresh meat and 'black pig' fresh and cured ham) from farm to consumer under EU conditions, including the Data Base management and a cost-benefit analysis.
