title: Molecular traceability of beef  from synthetic Mexican bovine breeds.
abstract: Traceability  ensures a link between carcass, quarters or cuts of beef and the individual  animal or the group of animals from which they are derived. Meat traceability  is an essential tool for successful identification and recall of contaminated  products from the market during a food crisis. Meat traceability is also  extremely important for protection and value enhancement of good-quality  brands. Molecular meat traceability would allow verification of conventional  methods used for beef tracing in synthetic Mexican bovine breeds. We evaluated  a set of 11 microsatellites for their ability to identify animals belonging to  these synthetic breeds, Brangus and Charolais/Brahman (78 animals). Seven  microsatellite markers allowed sample discrimination with a match probability,  defined as the probability of finding two individuals sharing by chance the  same genotypic profile, of 10(-8). The practical application of the marker set was  evaluated by testing eight samples from carcasses and pieces of meat at the  slaughterhouse and at the point of sale. The DNA profiles of the two samples  obtained at these two different points in the production-commercialization  chain always proved that they came from the same animal.
