A food-safety supplier review should establish whether the proposed site can control the hazards relevant to your product. Collecting certificates without checking their scope can obscure the practical questions about ingredients, processing, allergens and the conditions under which the food will be stored.
Look for product-relevant controls
Request the information needed to understand the food and the process. Ask how the site identifies hazards and verifies the controls it relies on. Review relevant records and the treatment of deviations with a qualified assessor where the product or process requires specialist judgement.
Check the supplier's procedures for ingredient approval, allergen management, sanitation and traceability. Ask how changes are assessed before they affect production. A document describing a procedure is useful, but implementation evidence is needed to understand whether the procedure is used.
Follow an incident through the system
Review how an affected batch would be identified, held and investigated. Establish the contacts and information required for a complaint or withdrawal decision. Where available, examine a relevant traceability exercise and the gaps found rather than relying only on a claim that the system exists.
Record the scope and limitations of your review. Certification and testing provide specific evidence; they do not guarantee that every future batch is safe. Approval should include any outstanding actions and the circumstances that would require reassessment.
