How do I delete an "unknown language"?

Unselect the images.
Delete the texts, but only the ones related to a language, be careful: name, ingredients, but NOT the nutrients.

What do I do if I find a product which is not food?

Just add "Non food product" as a category. The product will be moved later by administrators.

Nutri-Score

Why this product doesn't have a Nutri-Score?

Some products can't have a Nutri-Score:
- babies food
- ...
Some products can't have a Nutri-Score if their normal dilution is not precised
Some products are not complete enough to have a Nutri-Score computed:
- lack of category
- lack of nutriments

Why is there sometimes differences between Nutri-Score computed by Open Food Facts and Nutri-Score shown on the packaging?

A: There is three main reasons for that:

Sometimes our data are false; you can fix it in less than a minute by filling yourself the correct data
Sometimes we lack of data (such as % of fruit, vegetables and nuts or fibers); sometimes the producer has these informations but doesn't put it in its product...
Sometimes the producer made a wrong computation.

Quantity

You can find on this wiki some informations about quantities, but the specific article is a bit hard to read.

What if there are two quantities on the product?

Example: "poids net 300 g, poids net égoutté 175 g": https://world.openfoodfacts.org/product/5400113626084/mandarines-delhaize

A: write the both, as you read it on the product.

What to do if there is an "e" (or ℮) specified after the Quantity?

Example: https://world.openfoodfacts.org/product/7613036024419/le-bon-paris-herta

A: The "e-sign" (for "estimated") means that the quantity or volume is an average value (source: Estimated sign, Wikipedia). You can add an "e" if you see it or, better, use the ℮ sign. It's not a big deal if you cannot or forget it. If you feel very happy to use an ℮ you can have a look to all the products containing "e" instead of ℮: https://world.openfoodfacts.org/quality/quantity-contains-e

Ingredients

Do I have to fill the ingredients I know even if it's not written on the product?

For example, I know pork ribs contains pork. If the percentage of pork (nearly 100%) is not written on the package, do I have to fill the "ingredients" field?

A: Yes. You can write "Pork". Example: https://world.openfoodfacts.org/product/20207656/british-pork-loin-chops-strathvale

In the ingredients field, do I have to tell if ingredients are organic?

A: Yes. Example: https://us.openfoodfacts.org/product/00633109/organic-lentil-vegetable-soup-trader-joe-s

In the ingredients field, do I have to repeat "Ingredients"?

A: No you don't have to, but it's not a big problem.

Non-food products

I have seen a non-food product on openfoodfacts: is it normal?

A: Some contributors are publishing non-food products on openfoodfacts.org. While this is not a normal way to do, these products don't have any impact on food products' data, so it's not a big deal. From time to time, moderators moves them to our other databases.

I have seen a non-food product on openfoodfacts: what should I do?

A: you can:

either leave them as is: moderators will find them and move them to other databases
either add one of the following category, helping moderators to move them: Non food products, Open Products Facts, Open Beauty Facts, Open Pet Food Facts.
