The information and data is submited by the Open Food Facts contributors. The contributors also send pictures of the product, its labels, ingredients lists and nutrition facts table. When in doubt, visitors can thus check the accuracy by themselves, and if there is an error, they can correct it on the spot.

To detect potential errors more easily, we will progressively add automated checks. e.g. if the nutrition facts of a product are very different from products of the same category, it may be an error. If the nutriments add up to more than 100%, it's definitely an error.

Finally, many producers send us photos and data about their products using our Platform for Producers. If you are a producer, please contact us
