We manufacture pet food and are currently challenging our changeover matrix. In the human food industry, allergens and label claims generally drive the need for specific cleaning protocols. However, when it comes to pet food production, I’m wondering if there are any specific guidelines or industry best practices for cleaning between different types of proteins (e.g., poultry, beef, fish)? Is a rinse-out or wash-out required between these types of proteins required?
As we’re working with various label claims (such as “Grain-Free”), I’ve run into a challenge with determining acceptable limits for gluten testing to ensure sanitation is effective. In human food, there are clear guidelines for gluten content (e.g., <20 ppm), but I haven’t been able to find any similar requirements or recommendations for pet food. Does anyone have insights or practices for setting testing thresholds or sanitation effectiveness for pet food manufacturing, particularly with claims like "Grain-Free" or similar?
