Because of several events that led to severe sanitary problems, food safety had become one of the major issues related to quality. Traceability systems have been developed to guarantee the food chain from “farm to fork”. P MERCOSUR is the major beef exporter in the world. The typical production system is extensive, with big farms and natural pasture fed animals. Even though, diverse production systems manage different degrees of consanguinity. P DNA can be used to trace the entire production and retail chain. Microsatellites (STR) have been the most commonly used markers for identification in forensic and animal/crop sciences. Several researchers studied sample matching using different number and combinations of markers (AFLP, microsatellites, SNP) to trace meat.
