The chain-breaking of bovine spongiform encephalopathy (BSE) spread between ruminant species and from bovine to humans has been performed by the ban on ruminant-derived proteins in ruminant feeds. The necessity to evaluate the fraudolent use of rendered protein supplements leads to new and more sensitive analytical methods. Bovine mithocondrial DNA seems to be a good marker for this purpose and the polymerase chain reaction leads to an in vitro amplification of a specific target DNA sequence. In this study we could detect up to 0.0625% of bovine-derived material scattered in a commercial feedstuff. The DNA extraction method used is effective also on different kinds of foods wich have been subjected to high temperature (canned meat) or long ripening time such as Parmesan cheese.

Abstract
The chain-breaking of bovine spongiform encephalopathy (BSE) spread between ruminant species and from bovine to humans has been performed by the ban on ruminant-derived proteins in ruminant feeds. The necessity to evaluate the fraudolent use of rendered protein supplements leads to new and more sensitive analytical methods. Bovine mithocondrial DNA seems to be a good marker for this purpose and the polymerase chain reaction leads to an in vitro amplification of a specific target DNA sequence. In this study we could detect up to 0.0625% of bovine-derived material scattered in a commercial feedstuff. The DNA extraction method used is effective also on different kinds of foods wich have been subjected to high temperature (canned meat) or long ripening time such as Parmesan cheese.Pubblicazioni consigliate
