Yaourt périmé : peut-on encore le manger sans risque ?

According to the French National Agency for Food, Environmental and Occupational Health Safety (Anses), dairy products are among the most discarded foods in France, even when they don’t necessarily pose an immediate risk, even after the date on the package.

The result? Each year, nearly 10 million tons of food are wasted in France, a significant portion of which is fresh produce like yogurt, according to Ademe.

Expired Yogurt: Should You Follow the Expiration Date?

Expiration Date: What the Label Really Says

The first essential step before condemning a yogurt is to carefully read the information on the packaging.

Yogurts almost always have a “Use By” date (DLC in French), indicated by the phrase “to be consumed until.” Unlike the “Best Before” date (DDM), the DLC concerns microbiologically sensitive products, for which the manufacturer guarantees safety up to a certain date, provided the product has been refrigerated.

But, and this is an important nuance, slightly exceeding a DLC doesn’t automatically mean danger. According to the DGCCRF (French Directorate-General for Competition, Consumer Affairs and Fraud Prevention), yogurt that has been properly stored can sometimes be consumed several days after the date, without risk to a healthy person.

After the DLC, How Long Can You Eat Expired Yogurt?

In practice, expired yogurt can generally be consumed up to 7 days, sometimes up to 10–14 days after the date, provided that all of the following conditions are met:

• the yogurt has been kept refrigerated at all times (between 0 °C and +4 °C),
• the pot is intact (not swollen, not damaged),
• it has never been opened,
• no unusual odor, mold, or texture is detected upon opening,
• the person consuming it is in good health (not pregnant, immunocompromised, very elderly, or an infant).

Expiration: Why Yogurt Resists Time Relatively Well?

Yogurt is naturally acidic. This acidity, due to lactic fermentation, inhibits the growth of many pathogenic bacteria. In addition, the lactic acid bacteria it contains compete with any undesirable microorganisms.

This is why some specialists believe that yogurt can remain consumable up to one to two weeks after the date, provided it has never left the cold chain and the packaging is intact.

However, this tolerance does not apply to all dairy products. Some are much more sensitive from a microbiological point of view and must be consumed before the indicated date. This is particularly the case:

• raw milk,
• fresh cheeses (such as ricotta, cottage cheese, fromage frais, or certain fresh goat cheeses),
• fresh cream,
• dairy desserts (custard creams, flans, mousses),
• soft cheeses such as Camembert, Brie, or Reblochon, especially if made with raw milk.

Expired Yogurt: When Should You Stop?

Even if the date isn’t an immediate sentence, certain signals should raise an alarm. Expired yogurt should never be consumed if:

• the pot is swollen or damaged,
• an unusual odor is detected upon opening,
• the texture is abnormally liquid or lumpy,
• visible mold appears on the surface.

In these cases, don’t play the heroic taster – head straight to the trash. Anses reminds us that vulnerable people (pregnant women, infants, the elderly, or immunocompromised individuals) should apply the precautionary principle and avoid any product whose date has passed, even by a little.

What About “Natural,” “Greek,” or Fruit Yogurts?

Not all expired yogurts are created equal. Natural or Greek yogurts, less sugary and without pieces of fruit, are generally more stable than flavored dairy desserts or those with fruit, which contain more ingredients favorable to microbial development.

In other words, a natural yogurt expired by three days, kept well refrigerated, does not have the same risk profile as a fruit yogurt that has been started or poorly stored.

GOOD TO KNOW

According to DGCCRF and Anses, yogurt should always be stored between 0 °C and +4 °C to guarantee food safety. A break in the cold chain (even temporary, during transport or a long stay outside the refrigerator) significantly reduces tolerance after the date.
