We don’t always have the reflex to look at the expiration dates of what we eat. It’s the 12th of the month, and that container of salad you just devoured had a deadline of the 10th. Should we necessarily be worried? Not necessarily, reassures Dr Gérald Kierzek, but it all depends on the labeling and the type of food concerned.
Check the wording on the packaging: DDM or DLC?
Before you panic, the first thing to do is to analyze the product labeling:
- If the notice indicates a MDD (Minimum Durability Date)formerly called DLUO (Optimal Use By Date), so no stress. “It is a qualitative problem, the product may lose flavor, texture or color, but there is no health risk“, explains Dr Kierzek. This is the case for pasta, rice, biscuits, honey or even chocolate, which remain edible after the indicated date;
- If the notice indicates a
DLC (Expiration Date)attention is required. The foods concerned are highly perishable and can promote the development of pathogenic bacteria such as salmonella, Listeria or staphylococci. “These dates are established with a safety margin, but they must be strictly respected, particularly for products such as cold meats or creams.“, insists Dr. Kierzek.
One essential detail to keep in mind: these dates concern unopened products. Once a product has been started, conservation is no longer guaranteed. “When a product is opened, we should not rely on the DLC. Two or three days max, even if the date indicates that there is time left!“, warns the expert.

Observe your condition and symptoms
If you have consumed an expired product, there is no miracle solution to eliminate it from your body. There is no need to try to induce vomiting or take preventative medications. “The main risk is food poisoning, with symptoms like diarrhea and vomiting. But in most cases, it goes away on its own.“, reassures Dr. Kierzek.
In the majority of situations, the body naturally eliminates the responsible bacteria. However, some people are more vulnerable, notably babies, the elderly or immunocompromised people, for whom simple poisoning can be more severe.
When should you consult a doctor?
If digestive problems are bothersome but bearable, hydration is the priority. “The main risk is dehydration, particularly among vulnerable populations.“, warns Dr. Kierzek. If a person cannot drink, medical attention is recommended.
On the other hand, you should consult without delay if unusual symptoms appear. Botulism, a rare but serious infection, can be contracted by eating contaminated homemade canned goods. “If in addition to digestive symptoms, you have vision problems such as double vision, or neurological signs, you must immediately call 15“, warns Dr. Kierzek.
In summary, do not panic unnecessarily if you ingest expired food, but stay attentive to your body’s signals and react quickly if in doubt.
