What food-safety system should a feed-additive or premix supplier operate?

The system should reflect applicable law and product risks, with controls for supplier approval, incoming materials, hygiene, cross-contamination, process control, storage, release, traceability and corrective action. In the EU, feed-hygiene requirements and recognised good-practice guides support HACCP-based controls. For U.S. animal food, preventive-controls requirements may apply. Buyers should audit implementation and records, not rely only on a certificate title.
