Supplier Allergen Information: Verification & Ongoing Checks

For every ingredient you purchase, request a full product specification that includes a complete ingredient list with allergens highlighted, a "may contain" or cross-contact statement detailing allergens handled in the manufacturing facility, allergen status of the production line (dedicated or shared), country of origin where relevant (particularly for novel ingredients that may have different allergen profiles), and confirmation of whether the specification relates to a specific batch or is a general product specification. Generic product labels are not sufficient. A label tells you what allergens are deliberately included but may not disclose manufacturing cross-contact risks. The specification should go further. Many suppliers provide specifications through platforms like Erudus, Saffron, or directly via PDF. If a supplier cannot or will not provide a full specification, this is a red flag. You are accepting allergen risk that you cannot quantify.

Supplier formulation changes are one of the most common causes of allergen labelling errors. A sauce that was previously soy-free may gain soy lecithin as an emulsifier. A bread mix may switch from sunflower oil to rapeseed oil with no allergen impact, or to soybean oil with a significant one. You need a system that catches these changes. Request that suppliers notify you in advance of any formulation or manufacturing environment changes that affect allergen content. Build this requirement into your supplier agreements. At goods-in, train staff to check product labels on every delivery and compare against the current specification on file. If the label differs from the spec, quarantine the product until the discrepancy is resolved. Schedule periodic specification reviews with key suppliers (at least annually) to confirm that no unreported changes have occurred.
