How to Read French Food Labels and Expiration Dates

A French supermarket package can look familiar until three lines compete for your attention: a date stamped on the lid, à conserver au frais in tiny print, and an ingredient in bold. Reading French food labels safely is not a matter of translating every word. You need to know which line changes the decision.

Use the same five-step scan every time: identify the food and the exact date phrase, pair that date with its storage rules, find allergens, compare nutrition on a common basis, then check quantity and origin. The wording matters more than where the printer happened to put the digits.

This guide teaches that scan and the French behind it. It does not judge whether one particular product is safe for you or replace medical advice for an allergy or health condition. When a package is damaged, a label is unclear, or the cold chain may have been broken, ask the retailer or manufacturer and choose the safer option.

Quick answer: how do French food labels show expiration dates?

France uses two main date statements on prepacked food. DLC is a safety deadline; DDM is a quality date. Do not decide from the date alone. Read the words before it and the storage instruction beside it.

French wording	Abbreviation	Practical English	What to do
À consommer jusqu'au…	DLC, date limite de consommation	Use by	Respect the deadline and the stated storage temperature. Do not use smell or appearance to overrule it.
À consommer de préférence avant le…	DDM, date de durabilité minimale	Best before	The date concerns expected quality. If it has passed, first check that the package is intact and storage instructions were followed.
À consommer de préférence avant fin…	DDM	Best before end	The date may show only a month and year, or only a year, because it marks durability rather than a precise use-by day.

The DGCCRF's current date guide is explicit: a DLC must not be exceeded. A DDM may pass without making an intact, properly stored food unsafe, although taste, texture, aroma, or nutritional quality can decline.

Step 1: find the product name and exact date wording

Start with the dénomination de vente, the legal name that says what the food actually is. The large front label may say Délice du matin or show a pastoral picture. The smaller legal name may say préparation à base de fruits, yaourt au lait entier, or boisson aromatisée. That line is more useful than the marketing name.

Next, find the entire date sentence. The date itself may be printed on a lid, seal, bottle neck, or bottom. The label may point to it:

• à consommer jusqu'au: voir opercule means “use by: see seal”;
• à consommer de préférence avant fin: voir dessous means “best before end: see underneath”;
• date indiquée sur le couvercle means “date shown on the lid.”

DLC: à consommer jusqu'au

A date limite de consommation appears on microbiologically very perishable foods. Common examples include fresh meat, charcuterie, and refrigerated prepared dishes. The DGCCRF says these products may present a health risk after the deadline.

Treat the line as one unit:

À consommer jusqu'au 22/08/2026. À conserver entre 0 °C et +4 °C.

That means “Use by 22 August 2026. Keep between 0 °C and 4 °C.” If the product was not kept at the required temperature, the fact that the calendar date has not arrived does not restore the safety guarantee.

DDM: à consommer de préférence avant

A date de durabilité minimale says how long a product is expected to keep its specific qualities. You often see it on coffee, dry biscuits, pasta, tins, and other shelf-stable foods. After the date, a properly stored product in intact packaging may lose crispness, aroma, color, or some nutritional quality without automatically becoming dangerous.

DDM precision changes with shelf life. You may see a day and month, a month and year, or simply a year. Do not invent a missing day. Avant fin 10/2027 means “before the end of October 2027,” not “before 10 October.”

This distinction is not permission to ignore damage. A bulging, leaking, deeply dented, or badly rusted tin needs caution regardless of its DDM. If you are unsure, do not consume it. Infant nutrition also deserves special care: the DGCCRF notes that after its DDM, the guaranteed vitamin and mineral levels may no longer meet the product's intended nutritional specification.

Step 2: read French food labels with the storage rules

A date answers “until when” only under the conditions printed on the package. Look nearby for conditions de conservation, à conserver, or an after-opening sentence. This step prevents the most common mistake: treating a future date as a promise under any conditions.

French instruction	Meaning	Action
À conserver au réfrigérateur	Keep refrigerated	Put it in the fridge promptly. Check whether a temperature range follows.
À conserver entre 0 °C et +4 °C	Keep between 0 °C and 4 °C	The DLC relies on that range being respected.
À conserver dans un endroit frais et sec	Keep in a cool, dry place	Protect it from heat and moisture before opening.
À conserver à l'abri de la lumière	Keep away from light	Use a dark cupboard or follow the package's specific direction.
Après ouverture, à conserver au réfrigérateur	Refrigerate after opening	The unopened shelf rule has changed.
À consommer dans les 3 jours après ouverture	Use within 3 days of opening	Count from opening, even if the printed date is later.
Ne pas recongeler après décongélation	Do not refreeze after thawing	Follow the preparation and storage sequence on the label.

Once you open a package, do not keep relying on its unopened date. The DGCCRF explains that the printed DLC or DDM no longer supplies the relevant limit by itself after opening. Follow the separate time and temperature instructions instead.

Imagine milk with a DDM next month but the sentence à consommer dans les 4 jours après ouverture. If you opened it five days ago, next month's printed date is not the right decision point. The after-opening instruction is.

The same logic works in reverse. A chilled product can still be within its DLC, yet questionable because it sat warm for an unknown period. You cannot repair an interrupted cold chain by putting the food back in the fridge.

Step 3: read ingredients and allergens on French food labels

Find ingrédients before trusting a front-of-pack claim. Under French and EU rules, ingredients appear in descending order by weight at the time they are used. The first few items therefore tell you far more about the recipe than a flavor picture.

The DGCCRF's food-labelling guide also says allergens present as ingredients must be emphasized. A manufacturer may use bold type, capital letters, underlining, or a contrasting style. Scan for the visual change first, then read the surrounding ingredient.

How allergen wording works

Suppose the list says:

Ingrédients: pois chiches, eau, tahini (graines de SÉSAME), huile de colza, jus de citron, sel.

The emphasized SÉSAME is the allergen. It sits inside tahini, a compound ingredient, so reading only the main nouns would miss it.

You may also see:

• contient: lait, œufs (contains milk, eggs);
• peut contenir des traces de fruits à coque (may contain traces of tree nuts);
• fabriqué dans un atelier qui utilise… (made in a facility that uses…).

A “may contain” statement describes a possible unintended presence; it is not the same as an ingredient intentionally added to the recipe. For a serious allergy, do not guess from typography or assume an unlisted precaution means zero risk. Use the exact package, contact the manufacturer when information is ambiguous, and follow advice from your clinician.

Read percentages and unfamiliar terms

If an ingredient is highlighted in the product name or picture, its percentage may appear: fraises 12 % or noisettes 8 %. That figure helps you compare two products making the same promise.

Common label terms include:

• sucre (sugar), sel (salt), and huile de colza (rapeseed/canola oil);
• amidon (starch), levure (yeast), and farine de blé (wheat flour);
• conservateur (preservative) and colorant (coloring);
• arôme naturel (natural flavoring) and édulcorant (sweetener).

Notice the false friend: conservateur on food is a preservative, not a person with conservative politics. The wider guide to French false friends that can change your meaning will help you catch more familiar-looking traps.

Step 4: compare nutrition and Nutri-Score carefully

The back-of-pack table is the déclaration nutritionnelle or valeurs nutritionnelles. EU rules require the standard values per 100 g or 100 ml, which gives you a common basis for comparing similar products. A manufacturer may add a par portion column, but the per-100 figure remains the cleanest first comparison.

The European Commission's nutrition-labelling guidance lists the required core information: energy, fat, saturated fat, carbohydrate, sugars, protein, and salt. On a French table, look for:

French	English	Reading note
énergie	energy	Usually shown in both kJ and kcal
matières grasses	fat	Total fat
dont acides gras saturés	of which saturates	A subset of total fat
glucides	carbohydrate	Total carbohydrate
dont sucres	of which sugars	A subset of carbohydrate, not an extra amount to add
fibres alimentaires	fibre	May be included as extra information
protéines	protein	Shown in grams
sel	salt	Compare the same basis and your likely portion

Per 100 g is not necessarily your portion

Use 100 g/ml to compare like with like, then return to how much you will actually eat. If a jar contains 200 g and you use 50 g, your amount is half the per-100-g values. If a “portion” is 30 g but you normally serve twice that, the portion column understates your own serving.

Preparation matters too. A dry soup mix may list values tel que vendu (as sold) or préparé selon les instructions (prepared according to the instructions). Compare products in the same state. Water added at home can change values per 100 ml without changing what was in the sachet.

What does Nutri-Score tell you?

Nutri-Score is the colored A-to-E logo on the front of some packages. It is voluntary, so a missing logo does not itself prove anything about the food. Santé publique France explains that the score summarizes selected favorable and limiting components per 100 g or 100 ml. France has been rolling out a revised algorithm since March 2025.

Use Nutri-Score as a quick comparison aid, especially among products you might realistically substitute for one another. Then read the nutrition table and ingredient list for the detail you care about.

Do not use the letter as:

• a medical verdict about whether you personally should eat a product;
• an allergen check;
• proof that one portion size suits you;
• a food-safety signal or substitute for DLC, DDM, and storage rules;
• the whole story of your overall diet.

An A does not override an allergen. An E does not mean the package has expired. The systems answer different questions.

Step 5: check net quantity, origin, and instructions

Finish with the details that help you compare value and understand what the origin claim really covers.

Poids net versus poids net égoutté

Quantité nette is the amount sold by mass or volume. You may see poids net: 400 g on a tin or volume net: 1 L on a bottle. When food sits in a covering liquid, the package may also show poids net égoutté, the drained weight.

A jar marked poids net 370 g; poids net égoutté 190 g contains 190 g of the drained food. Compare the drained figure if that is the part you plan to eat. Package size alone can be misleading.

Origin and manufacture are different clues

Look for origine, provenance, élevé en (raised in), abattu en (slaughtered in), or pêché en (caught in). Origin is mandatory for certain foods and where leaving it out could mislead. It is not a universal line on every processed package.

Fabriqué en France means manufactured in France. It does not automatically mean every ingredient came from France. If a product displays a French origin while its primary ingredient comes from elsewhere, the label may need to clarify that difference. Read the small origin sentence rather than treating a flag as the whole answer.

Finally, check mode d'emploi (instructions for use). À cuire à cœur means cook thoroughly to the center; bien agiter avant emploi means shake well before use. These directions can affect safety or expected quality, so they belong in the decision, not in the vocabulary pile you skip.

Worked example: how do you read a fictional French label?

The package below is entirely fictional and does not copy or describe a real brand. It is designed to show how the five-step scan works.

Tartinade de pois chiches au citron

Ingrédients: pois chiches 64 %, eau, huile de colza, jus de citron 5 %, tahini (graines de SÉSAME), sel, cumin.

Poids net: 180 g.

À consommer jusqu'au 22/08/2026. À conserver entre 0 °C et +4 °C. Après ouverture, à conserver au réfrigérateur et à consommer dans les 2 jours.

Valeurs nutritionnelles moyennes pour 100 g: énergie 690 kJ / 165 kcal; matières grasses 10 g, dont acides gras saturés 1,1 g; glucides 14 g, dont sucres 1,5 g; fibres 5 g; protéines 6,5 g; sel 0,8 g.

Fabriqué en France avec des pois chiches originaires d'Espagne.

Here is the reading order:

1. Identify the food and date type. It is a chickpea-and-lemon spread with à consommer jusqu'au, so the date is a DLC, not a best-before suggestion.
2. Attach storage to the date. The unopened product must stay between 0 °C and 4 °C. Once opened, refrigerate it and use it within two days, even though 22 August has not arrived.
3. Find the allergen. Sesame is emphasized inside tahini. Chickpeas are the first ingredient and make up 64%; lemon juice is 5%.
4. Read nutrition on the stated basis. Every figure is per 100 g. The jar contains 180 g, so eating the whole jar would not equal the displayed 100-g amounts.
5. Separate quantity and origin claims. Net quantity is 180 g. The spread was made in France, while the chickpeas came from Spain. Those statements are compatible and answer different questions.

This example also shows why a front claim cannot do all the work. “Made in France,” “with lemon,” or a colored nutrition logo would not tell you the date type, the sesame allergen, or the after-opening window.

French food-label vocabulary worth learning

Learn these as chunks, not isolated translations. Store la liste des ingrédients, not only ingrédients. The same article+noun habit from this guide to learning French noun gender makes the phrases easier to retrieve.

French chunk	Useful English
la dénomination de vente	legal name of the food
la liste des ingrédients	ingredient list
les allergènes	allergens
peut contenir des traces de…	may contain traces of…
la date limite de consommation	use-by date / DLC
la date de durabilité minimale	best-before date / DDM
les conditions de conservation	storage conditions
après ouverture	after opening
les valeurs nutritionnelles	nutrition values
pour 100 g / par portion	per 100 g / per serving
le poids net / le poids net égoutté	net weight / drained net weight
l'origine / la provenance	origin / provenance
le mode d'emploi	instructions for use
le numéro de lot	batch/lot number

If the print is tiny or a detail is missing, these questions are enough:

• Excusez-moi, vous pouvez me montrer la date limite? (Could you show me the use-by date?)
• C'est une DLC ou une DDM? (Is it a use-by date or a best-before date?)
• Il faut le garder au réfrigérateur? (Does it need to be kept in the fridge?)
• Où sont indiqués les allergènes? (Where are the allergens shown?)
• Est-ce que ce produit contient du sésame? (Does this product contain sesame?)
• C'est le poids net ou le poids égoutté? (Is that net weight or drained weight?)
• L'ingrédient principal vient d'où? (Where does the main ingredient come from?)

Say each question once now. A sentence you have spoken is easier to retrieve beside a busy shelf. If you are preparing for a trip, add them to your French for travel speaking plan. When the groceries turn into a café visit, the French café conversation script takes you through ordering and clarification.

A final safe label check

Before the product goes into your basket or onto your plate, ask five questions:

1. What is the food's legal name, and does the date say jusqu'au or de préférence avant?
2. Were the required storage conditions respected, and what changes after opening?
3. Are any allergens emphasized or mentioned in a precautionary trace statement?
4. Am I comparing nutrition per 100 g/ml, then adjusting for the amount I will actually eat?
5. Do net quantity, origin, and preparation instructions match what I think I am buying?

The useful skill is not translating the entire box. It is knowing where to slow down. Date wording and storage belong together. Allergens outrank marketing copy. Nutri-Score is a shortcut, not a medical judgment. A French flag may describe manufacture rather than every ingredient.

Run the same scan on your next package. The print will still be small, but the decision will be much clearer. To rehearse the shelf questions aloud before you shop, try a short Spokira speaking session.

Use the French supermarkets guide for foreign shoppers to see where this label scan fits into the whole trip. For the two storage surprises learners ask about most, read why eggs are not refrigerated before sale in France and why much of the milk is shelf-stable until opening. Once the basket is ready, the French supermarket checkout guide covers the questions you will actually hear.
