Few problems facing the feed indust

Few problems facing the feed industry are more acute than those of salmonella in animal feeds. The safety of meat products, and, specifically, poultry products, has received a great amount of national attention in the last decade. Williams (1981) concluded that feed-borne salmonella infection is one of the most important causes of infection to poultry flocks and subsequently to human consumers. Proper preconditioning (Fung and Sunderland, 1991) and extrusion cooking are able to density salmonella organisms while doing little or no harm to the quality of the protein.
