When confronted with a yogurt, a tray of meat, or a fish whose expiration date is near, many consumers share the same reflex: freezing everything to “save” the food and prevent waste. An action that seems sensible, especially when the date falls on the same day, but which can in reality lock in a health risk rather than erase it.
The French authorities, from the DGCCRF to the Service-Public.fr website, regularly remind that the DLC is not merely a quality indicator but a sanitary boundary. Why, then, does freezing a food with a DLC not solve the problem, and how can one act without taking risks or throwing things away blindly?
DLC, DDM: read the label carefully before freezing a food
For highly perishable products, the Date Limite de Consommation is always indicated by the label “To be consumed by…”. The DGCCRF page notes in plain terms that “A date limit of consumption, DLC, must not be exceeded,” because these foods can become dangerous starting the next day.
The Date de Durabilité Minimale (DDM), by contrast, concerns less fragile goods, with the label “Best before…”. When this date has passed and the packaging remains intact, the DGCCRF states that these products “can be consumed without risk by the consumer,” even if they have sometimes lost in taste or texture.
Why freezing a DLC-at-risk food does not make it any safer
Foods that fall under a DLC are described as “microbiologically highly perishable”: fresh meats, fish, cured meat products, refrigerated prepared dishes. For these items, the DGCCRF specifies that “The product can no longer be marketed beyond this date and is likely to present a risk if consumed,” because pathogenic bacteria can develop rapidly.
The Ministry of Agriculture reminds us that freezing does not sterilize food: most microorganisms survive, their multiplication is merely paused. In a domestic freezer, cooling is slow; a bacterium that divides every 20 minutes can multiply by 1,024 in a few hours before the deep freeze even halts it.
DLC today: what to do and when to freeze a food
The day the DLC expires presents two possible scenarios. If the food has been properly stored, with no break in the cold chain, it should be consumed or cooked on the same day, in accordance with basic hygiene rules; freezing is no longer a safe option. Service-Public.fr also reminds that a break in the cold chain can render a product dangerous even before the indicated date. If the date has passed, authorities recommend not consuming it, even if it looks appealing.
To avoid this dilemma, the Ministry of Agriculture advises freezing a food well before its DLC, ideally as soon as you return from shopping or just after preparing a dish. Once the packaging is opened, the printed date becomes much less reliable: it is better to rely on the manufacturer’s guidance, “to be consumed within X days after opening.” Before filling the freezer, a few simple guidelines help decide:
- Product is still well before its DLC, or within the window indicated after opening.
- Cold chain has been maintained since purchase or preparation.
- Rapid freezing in clean packaging, with the date written on it.
