DLC vs DDM: Don't throw away uselessly

Hygiene & Regulation 5 min read 20 janvier 2026

DLC (Date Limite de Consommation): “To be consumed by…” Fresh, perishable product (meat, yogurt). Strict prohibition of use or sale after the date. Health risk.

Best Before Date (Minimum Durability Date, formerly DLUO): “Consume before…” Dry product, retains freshness, beverage. The product may lose flavor but remains safe. Usable after the date (unless altered in appearance).

Side DLC: Once opened, a product (e.g., milk brick, ham) has a short lifespan (e.g., 3 days). You must write the date of opening on the packaging.

Homemade Products: You must define their shelf life (e.g., 3 days for homemade mayonnaise) through aging tests or best practice guides.
