Human and animal salmonellosis is still causing high economic losses. In humans, the main infection vector is related to poultry product consumption. The US Agriculture Department has reported that animal feeds are the main source of infection in poultry production, and Salmonella enteritidis is the most frequently isolated serotype. It may be present in feeds at such low levels that it is difficult to detect, but nevertheless it proves to have a high colonization ability in poultry. The control methods for Salmonella in animal feeds depend on the effectiveness of feed decontamination and the prevention of recontamination. Bactericide products and methods combining temperature and duration, etc., can be used, all of them complemented with biosecurity measures to make sure recontamination does not occur. Since raw materials are an important reservoir of Salmonella, it is of utmost importance to ensure a total decontamination of feeds, especially in poultry production
