EFSA publishes advice on salmonella and other biological hazards in animal feed

EFSA’s BIOHAZ Panel Chair, Dan Collins, said, “Animal feed can be a source of several types of Salmonella. Eliminating Salmonella in animal feed even before it gets to the farm will make a contribution to reducing Salmonella in our food. EFSA with its comprehensive risk assessment mandate, from animal health and welfare, to food and feed safety is uniquely placed to provide a comprehensive risk assessment view on Salmonella and other microbiological risks. This opinion is a good example of how EFSA is moving towards an integrated approach in its risk assessment work.”

The Panel concentrated on industrially-produced feed in its evaluation, as this type of feed is most at risk from Salmonella contamination. Presently, there is limited information available on the occurrence of Salmonella in “home” mixed feed, and the Panel recommended that more information be gathered. Oil seed meal and animal derived protein En type molekyle sammensat af en kompleks kæde af aminosyrer (proteinbyggesten). are the main type of feed materials introducing Salmonella into industrially-produced feed. Although industrially-produced feed is generally heat treated during the production process to kill Salmonella and other bacteria, it can become recontaminated following the industrial process during cooling and further handling. Heat treatment is generally recognised as the most effective decontamination method. However, chemical treatment may offer an alternative means of protection from Salmonella and other microbiological risks. The Panel called for more research on the efficiency of chemical feed decontaminants in combating Salmonella.

In its opinion, EFSA’s BIOHAZ Panel made a series of conclusions and recommendations:

• Feed manufacturers should aim to continuously reduce the occurrence of Salmonella in animal feed.
• A baseline survey on the testing of Salmonella in feed across the European Union should be considered in order to ensure comparable data between Member States, and to inform decisions to improve the control of Salmonella in feed production.
• There should be effective implementation of Good Manufacturing ( GMP God fremstillingspraksis er enhver praksis vedrørende de betingelser og foranstaltninger, der er nødvendige for at sikre fødevarers sikkerhed og egnethed i alle leddene i fødevarekæden.^[1]) and Good Hygiene (GHP^[2]) practices, and HACCP HACCP (risikoanalyse og kritisk kontrolpunkt) er et system, der identificerer, evaluerer og kontrollerer farer for fødevaresikkerheden. Det anvendes af fødevarevirksomheder til at garantere sikker produktion, opbevaring og transport af fødevarer.^[3] principles throughout the feed chain. Proper control of recontamination, and effective heat treatment at feed production plants should be ensured.
• Feed safety criteria based only on testing of the end product would not be an effective way to ensure absence of Salmonella contamination. There is a need to establish one or more process hygiene criteria along the feed production chain (testing for Salmonella at key sampling points at crushing plants, rendering plants and feed mills, as well as on the end product).
• A common EU standard method for monitoring Salmonella in animal feed should urgently be validated for use in feed.
