ISSUE FOCUS FEED & ADDITIVE MAGAZINE August 2023 31 fluence contamination and transmission of Salmonella. The Selko Salmonella Control Programme 5 stepby-step approach includes (Figure 2): 1. Define: Profile and understand the producer’s objective 2. Assess: An audit assesses the entire production environment 3. Design: A value-added programme is tailored to the producer’s goals and the assessment findings 4. Implement: A team of experts implements the plan 5. Monitor: The team evaluates results and decides on next actions within the programme CONCLUSION Optimising the safety of poultry feed and water and strengthening the digestive system of the birds makes it more difficult for Salmonella to enter the feed-to-food chain. Feed hygiene/decontamination, coupled with good manufacturing practices, are effective to reduce Salmonella risk in feed. Additionally, including water additives that strengthen innate defence mechanisms along with specific feed additives can make Salmonella colonization and spread more challenging. This “outside/inside” approach can play a role in reducing food-borne illness and supporting safety across the food chain. References: 1Nair, D.V.T. et al. 2018.
