https://world.openfoodfacts.org is a collaborative site created and fed by consumers to be able to decipher labels and compare products.

For more information about a product or a claim, write to the manufacturer. We do not have contact information for manufacturers but they are most often on the packaging.

If you want to help us bring more transparency to consumers like you or us, you can use our iPhone or Android app to add products: https://openfoodfacts.app

And to discuss about the project, you can join the Facebook group of contributors: https://www.facebook.com/groups/openfoodfacts/ or chat with the other contributors on Slack:

The Eco-Score is based on the calculation of the life cycle analysis produced by ADEME (the ecological transition agency) and INRAE (the national institute for agronomic research). About fifteen components are calculated and linked to create the PEF score.

To this PEF score are added bonuses and maluses (mode of production, origin of

ingredients, endangered species, packaging) in order to calculate the Eco-Score.

For more information, see the summary page https://world.openfoodfacts.org/eco-score-the-environmental-impact-of-food-products on Open Food Facts as well as on the Eco-Score consortium website. (Eco-Score presentation https://docs.score-environnemental.com/)

For the Eco-Score to be calculated exactly, the percentage of each ingredient and its origin must be specified.

If this information is not already specified in the list of ingredients, you can add a column to mention it, with the following format:

Wheat flour 16% (France)

Chocolate 8% (Ivory Coast, Ecuador)

We need also the components of the packaging in the form of: 1 plastic film to throw away, 1 FSC cardboard box to recycle, 6 PET transparent plastic bottles of 1.5 L to recycle, 6 opaque colored plastic caps, 12 plastic cans 33 cl aluminum.

To better understand the PEF system, you can read: explanation of the PEF score on the Eco-Score methodological site

The local aspect concerns the origin of the raw materials. This is why it is important to enter their percentages as well as their origins in the list of product ingredients or in the field dedicated to the origins of ingredients.

If you wish to share the information on the origin of the raw materials on your sheets, we invite you to include them in the list of ingredients.

https://world.openfoodfacts.org/nova

Currently, there are no exports dedicated to specific countries.

There are many ways to use our different exports combined with different tools to select the data related to a specific country.

You can have a look at some of this techniques on our wiki.

In the event of a problem with your Nutri-Score, check that your information is correct on the “modify” tab of your product sheet. If any information is missing or incorrect, do not hesitate to contact us at producers@openfoodfacts.org

The calculation of the Nutri-Score will be done with the nutritional table of your product.

Don't forget to include the percentage of fruits, vegetables and nuts in your table, so that the calculated Nutri-Score is not incorrect.

The Nutri-Score is managed by Santé Publique France. It summarizes the table of nutritional values ​​so that everyone can understand it. The goal is to provide access to clear and understandable nutritional information for everyone.

The main difference is for us a critical one: our data is freely available to all and for all uses. It's what is called open data.

Almost all other sites, services and applications forbid others from reproducting and reusing their data. Quite to the contrary, they jealously keep it for themselves. In almost all cases, their terms of service explicitly forbid any non-personal use and any extraction of all the data or parts of the data.

We consider that food products information is too important and useful to keep it locked in a safe. So when we started the Open Food Facts project and mobile app, back in 2012, we decided to do exactly the opposite: not only we allow use and reuse of our database, freely and without fee, to everyone and for all uses (including commercial), but we also encourage it!

Making the data publicly available (what is known as open data) allows individuals, associations, companies, researchers etc. from all around the world to think up and develop applications for the data that we certainly would never have thought about.

Contributors are volunteers. Their contributions are gathered in an open database that can be used by everyone and for all uses. (see the Terms of reuse)

Everyone (including but not limited to Open Food Facts contributors and creators) can thus redistribute and/or reuse the data to build web sites, services, software, mobile applications, or to write articles and studies. They are free to make the resulting work freely available, or to sell or monetize it (e.g. with ads), as long as they respect the terms of reuse.

We are also strictly independent from the food industry, and all the services and software we build are free. For example, our Platform for Producers is totally free, and we are all the more pleased with that because we think it might help them improve their products.

Probably not. Almost all other sites forbid reproduction and reuse of their data and images, and that is actually the reason why we have created Open Food Facts: to make all this data available to all and for all uses.

To avoid any legal problem, we therefore ask contributors to only add pictures that they took themselves, and only data that is coming from the product packaging and label.

You can ask questions or make suggestions on theforumor contact us by e-mail:contact@openfoodfacts.org

If you are a producer, please email us at producers@openfoodfacts.org.

If you are a journalist, please email us at presse@openfoodfacts.org.

Please note: Open Food Facts is a collaborative database of food products, we do not sell any product and we do not have links to their producers. For a question or complain about a product, you need to write directly to the producer (address on the product label).

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

Yes! The only condition is to accept that the data and the pictures be made available under an open licence. (see the Terms of contribution)

We have developped a free platform to let you easily import photos and data about your products, regardless of your size. It will let you import complete and up-to-date data and visuals into Open Food Facts that will be visible in more than 100 other nutritional apps. Additionaly, the platform provides suggestions to improve the Nutri-Score of your products. Contact-us to discuss how we could proceed: producers@openfoodfacts.org

It would take too long to list all the organizations that rely on the Open Food Facts platform.

• More than 100 mobile applications

address the needs of many audiences: diabetes (VeryDiab), allergies, food balance via artificial intelligence (FoodVisor), disabilities, and more. Our database also allowed the creation of Yuka.

• Lots of websites: CombienDeSucres.fr,

CestEmballePresDeChezVous.fr...

• Data-journalists : Les Décodeurs du Monde, BFM

TV

• Researchers in nearly 100 scientific

articles

• Food banks and solidarity stores: a

Data For Good project in the continuity of a pilot project initiated by the French Red Cross, integration in the cash management of a small food cooperative.

• Companies: Terraillon uses our data

to give life to its connected scales.

• Programming schools (Simplon, Open

Classrooms) have integrated Open Food Facts as a motivating project in their curriculum.

Each animal is different (a snake does not have the same nutritional needs as a cat or a dog)

Even within the same type of animal such as dogs, the nutritional needs vary according to the life of the sedentary lifestyle, a possible castration or diseases.

It is therefore complicated to calculate a score for animal feed without involving dozens of researchers and creating dozens of different algorithms, which has not been done to date.

Open Pet Food Facts API is 98% the same as Open Food Facts API so if you use Open Food Facts API documentation you should have a pretty clear view of the Open Pet Food Facts API.

Note that features like the Knowledge Panels, Eco-Score, Nutri-Score are not supported (either due to the topic, or to the old codebase).

That may depend on countries, if network is slow or expensive. anything above 5000 pixels in weight or height is probably not very useful. and if you can somehow detect that network is slow, then even a 2000 pixels image would be great (certainly better than not having an image!)

Open Food Facts contains only information about packaged food. For average values of produce (for example, tomatoes or bananas) and other food products, you can use one of the official national nutrition databases instead.

Note: The list below contains some of the most important national food databases. If you think some other database should be included in the list, please contact us at: https://world.openfoodfacts.org/contact

Unfortunately it's not yet possible to easily search on product name only and precisely through the API.

Using a filter on category might help you make your search more precise though.

On Open Food Facts’ main page, at the top left corner of the screen, there’s a scrolling menu. At the bottom of it, you’ll find the “advanced search” option, on which you can click. It is then up to you to determine which criteria are the most relevant to your project(s). Once chosen, you’ll be able to download the obtained results by scrolling down at the bottom of the page and clicking on “Download results”.

You can also consult:

• Our API documentation: https://openfoodfacts.github.io/api-documentation/
• Open Food Facts' Terms of Use: https://world.openfoodfacts.org/terms-of-use
• On our data: https://world.openfoodfacts.org/data

All the documentation about API usage can be found on the API documentation page, but here is a quick summary:

• The Open Food Facts database is available as open data under the Open Database License (ODbL), see https://world.openfoodfacts.org/terms-of-use for the legal details. The two conditions are attribution and share-alike. If you combine data from Open Food Facts with other databases, then the ODbL requires that the resulting database must be released as open data as well. It also means that you can combine the data only with sources that would allow such redistribution.

• You must always use a custom User-Agent when performing API calls to identify your app.

• Rate-limits are enforced for each API endpoint.

Currently, we don't offer historical data dump (JSONL, MongoDB, CSV).

However, for individual products, it's possible to access previous versions of the product data using the API or on the product page using revisions.

Every time a product is updated, a new revision (increasing digit starting from 1) is created.

For example, to get the first revision (=first product version) of this product, use

https://world.openfoodfacts.org/product/7623186089763/joghurt-baumnuss-migros?rev=1.

Similarly, the rev parameter can be used with the API:

https://world.openfoodfacts.org/api/v2/product/7623186089763?rev=1

Only moderators can remove photos, to avoid potential vandalism.

Just ask on Slack or at contact@openfoodfacts.org to remove your duplicates or any inappropriate photos (you should try to provide the barcode number or URL to so).

We also have a new image report API if you're a programmer.

We coordinate all design related activities on https://github.com/openfoodfacts/openfoodfacts-design and on a dedicated chat channel. We regularly do team meetings and brainjams on specific challenges.

99% of the time, producers will create different barcodes for different versions of their products. A famous example is the difference between French and German Nutella in terms of thickness, due to difference in bread across countries. 2 different formulas, 2 different barcodes.

Barcode clash can however happen on shorter codes (EAN-8) that are typically reused by some stores across Europe and the US. We don't currently handle those barcode clashes, but it should be doable to do so by getting the user's general location (it's even more rare to have barcode clashes within a country).

In the long term, we encourage producers to move to EAN-13 to avoid those barcode clashes.

Please contact : presse@openfoodfacts.org https://blog.openfoodfacts.org/en/press-release-new-mobile-app

Here is the process:

• find the canonical name of the label in the labels' taxonomy (it's the first item in the list of the labels' synonyms, eg. en:100% vegetable)

- get the logo in a good quality: avoid using the contributor's photo which are not suited for this case; most labels have official websistes high quality logos, sometimes in vector format (even better for us); as long as we use a logo to objectively inform about the presence of a label on the packaging of a product, there is no need to ask permission. - name the file like this:   name-of-the-label.[width]x90.png  where width is the width for the logo when it is 90 pixels high. The filenames need to be unaccented, in lowercase and using "-" instead of spaces.

• then add the logo in the directory that corresponds to its canonical name. If the canonical name is en:something, then they need to be in /en/. The root directory for logos is https://github.com/openfoodfacts/openfoodfacts-server/tree/main/html/images/lang

Head over to https://wiki.openfoodfacts.org/Country_Support

Please ask contact@openfoodfacts.org for edit access to the knowledge base.

No you don't. You just need to update the English one

• Create your PR

Once it's merged, we will rebase crowdin-trigger manually and the Crowdin translation system triggerd by GitHub Actions will do the rest for other languages.

GitHub bot then creates a new PR automatically that we then review.

Any information you have is welcome, from nutritional information to packaging information.

This makes it possible to establish a complete file, to calculate all the scores with precision and more generally a transparency appreciated by consumers.

However we do recommend you prioritize the following fields:

• Nutritional information
• Product category (e.g. drinks, cheese, yogurt, etc.)
• Name of the product
• Allergens
• and the ingredients, this field is not mandatory but recommended for an optimal usage and determination of the scores

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

You can download all the data available on Open Food Facts. Beware, this requires a lot of disk space, a powerful computer if you want to use a spreadsheet or knowledge of R or Python otherwise.

You can also download a subset of the data (your brand for example) thanks to the advanced search.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

Absolutely, and it will be forever. All services provided by Open Food Facts are free of charge. We are very pleased that you have decided to contribute your product data to food transparency, and we thank you for this.

Thank you for your willingness to participate in food transparency!

The Nutri-Score, NOVA group and Eco-Score are calculated based on the data present in Open Food Facts. Our algorithms strictly follow the official methodologies of these scores.

The purpose of these indicators is to provide easy-to-understand information for the consumer.

The NOVA group deals with the transformation of the product, theEco-Score with its environmental impact and the Nutri-Score with the nutritional elements, knowing that the more a product has scores close to A, the more qualitative it is.

The 3 scores do not deal with the same elements. It is therefore not possible to compare them with each other.

By registering on the producers' platform and upload your products' data, you can compute the Nutri-Score and Eco-Score associated with your products.

However, you must delete it once the simulation has been carried out so that it is not exported to the public platform with the products already marketed in your range.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

Yes, please email producers@openfoodfacts.org, so we can link all accounts to the same company.

You can access the Pro platform with your existing account's credentials.

If you are a professional, you will need to use your professional email address so that we can validate your account.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

There are a few resources to help you make the most out of the Pro platform.

You are welcome to:

• check our user guide - we invite you to download the PDF so that the links are clickable, which will ease your navigation through the document.

• consult our video tutorials

• share feedback or suggestions via this form

• Schedule a call with Manon, our partnerships manager, if you have more questions: here

• Contact us via email: producers@openfoodfacts.org

To continuously improve the quality of the data we rely on 4 pillars:

1. The community is constantly adding data and photos and is a veritable patrol of reviewers.

1. We have set logic rules to identify errors on the product sheets. For example: if the sum of the weight of the ingredients is greater than the total weight of the product, there is an anomaly. We have around 50 others quality checks.

1. Thanks to Machine Learning, we limit the risk of input errors. Our technology allows us to extract textual data from photos taken by contributors

1. Thanks to the support of Santé Publique France, we developed a portal allowing producers to upload their mass-produced data and thus correct/complete the community's contributions.

To add products to our platform, you first need to decide how you want to proceed. There are 4 options:

• Manually: if you have a small number of products, it is still possible to create each product sheet by hand on the Pro Platform.

• Via a spreadsheet import: you can download the spreadsheet template provided by Open Food Facts, or import directly an extraction from your IT system into the Pro platform.
• Via product catalogues' connectors. If you are client at EQUADIS, AGENA3000 or BAYARD, you can upload data in Open Food Facts in 1 click. If you are working with another PIM (Product Information Management), please contact us : producers@openfoodfacts.org
• Via a tailored connexion between your company and Open Food Facts. If you count more than 1000 products in your portfolio, we can discuss the opportunity of build a specific connector to ease the data transfer.

For more details, we invite you to download our user guide and/or consult our video tutorials :-)

Yes, if you use EQUADIS, AGENA3000 or BAYARD product catalogues, and set up the right configuration, the import can be done automatically and therefore update the product data on Open Food Facts.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

There is no limit, you can upload the number of products you want on our platform.

If you want to remove a product that is no longer available on the market, you just have to check the box "this product is no longer sold" when you edit your product sheet.

If you want to remove several products, we recommend you follow the procedure mentioned in the user guide, on p. 18.

You can also contact us via producers@openfoodfacts.org if you have any questions.

When the product is archived, it will no longer appear in Open Food Facts. It will however remain in our database so that we can keep a history of products sold over time.

When a producer places one of his products online with his producer account and a product sheet already exists, this will complete it.

The information that the producer will have posted will always have priority and he alone will be able to modify his products when the information is filled in.

If the data sent via the platform is fragmented, the information added by the community from the packaging may complete it.

A template is provided by Open Food Facts.

However, any spreadsheet format (xlsx, csv) will be importable in the platform. Our algorithm is designed to automatically match the attributes from your file, with the ones present in Open Food Facts. Beware to always double-check the matching stage as you may need to adjust manually some of them.

If your information is fragmented between several spreadsheets, you can import them consecutively - making sure to do the matching if the format changes.

You can also import an Excel file in addition to an EQUADIS or AGENA3000 import, if the data is not yet in your information system. In these cases, don't forget to request an export to the public database from the interface.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

Manufacturers can now send their product data and photos in real time from Equadis, AGENA3000 and BAYARD consulting to Open Food Facts.

You will of course also benefit from the reformulation suggestions and all the features of the platform.

Our blog post explains the steps to follow if you are an EQUADIS customer.

If you are an AGENA3000 customer (Product A3 PIM INDUSTRY), you just have to select the recipient "Open Food Facts" when sending your product sheets. More information on this blog post.

If you are a customer of another product data catalog (Salsify - ex-Alkemics, ConsoTrust, 1worldSync, Akeneo, PIMWorks, etc.) please let us know at producers@openfoodfacts.org

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

For products without a barcode, on the site or on the producer platform, there is a "Product without barcode" button in the left column which allows you to add them. An identifier is then generated automatically.

We have created specific projects for cosmetics, for animal feed, as well as for other products:Open Beauty Facts,Open Pet Food FactsandOpen Products Factsrespectively. We are therefore happy to be able to import your products into the project that suits them.

Yes of course! You can take control of the associated producer account by creating an Open Food Facts account with your business address. When you register, mention the name of the organization present on the form to be able to access the corresponding producer space.

A short validation step will be necessary to ensure that you are indeed the producer.

You will be able to complete the data, add images, obtain automatic recommendations for improving the Nutri-Score, and much more. All this is of course completely free. You can also connect a third-party product data management system such as EQUADIS , AGENA3000 and Bayard consulting.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

It depends on the apps. For those that use our APIs, which is the vast majority, it is immediate. For the ones that use our daily exports, it's D+1 provided that they update it.

We use the barcode to identify products, if you import a record with the same barcode as an existing record, the information will be merged.

For data such as ingredient list, nutritional values (only one correct value possible), the data sent via the producer platform will overwrite the existing data.

For data such as labels/categories/brands (several correct values possible), the information is merged. If data is incorrect on the public platform, you can modify the product sheet on the public platform to remove the incorrect values.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

The order of the ingredientsis important: it represents the order by quantity. The best way to fill the ingredients is to follow exactly what is written on the packaging. That's why it is also so important to have photos of the ingredients printed.

You can send images but in practice only the main image will be selected automatically, the other images will be sent, but not cropped / selected for ingredients, nutrition etc.

You can access the pro platform’s tutorials:

• Via the pro platform itself: https://world.pro.openfoodfacts.org/

• Directly on YouTube

→ You can also download our user guide

When you are on the home page of the Producers Platform:

1. click on the link "→ Number of products with improvement opportunities" at the top of the page.

1. you can consult all the opportunities detected by our system to improve your products

1. clicking on a type of opportunity will lead you to the list of products that are subject to improvement.

→ For more details, we invite you to download our user guide and/or consult our video tutorials :-)

As a label, as you are not the direct producer of the products, you do not need to create a producer’s account.

As a label the most relevant thing to do is to contact us (producers@openfoodfacts.org) and send us the list of the products on which your label is displayed so that we can add them on the related product sheets.

As a producer, the most efficient way to add packaging data to your products is by filling in this excel spreadsheet the necessary information, from column "AU".

For each packaging component, you will need to enter:

• The number of units (ex: 4 pots of yogurts)

• The shape (ex: pot, lid, box, etc)

• The material (ex: PET, paper, glass, etc)

• The recycling instruction (ex: to recycle, to discard, etc)

• The weight of one empty unit (in gr)

• The net quantity of product contained per unit

This spreadsheet can then be imported into our platform dedicated to professionals.

The "Tackling Food Packaging" project consists of collecting detailed information on the packaging of the most consumed products (shape, material, sorting instructions, weight, capacity).

Based on a participatory science approach, it will rely both on companies agreeing to share their packaging data and to play the game of transparency, and on citizens allowing the collection of information on products. This information will be freely reusable ("open data").

For more info: https://blog.openfoodfacts.org/en/packaging-projet-producers

Even after the end of the project, it is possible to add packaging data as the packaging fields will remain on our website.

Open Food Facts, is an open database, an open project which is operating under an ODbL license, therefore as long as you agree with the requirements of the ODbL license, you are welcome to re-use our data for your projects :).

On Open Food Facts’ main page, at the top left corner of the screen, there’s a scrolling menu. At the bottom of it, you’ll find the “advanced search” option, on which you can click. It is then up to you to determine which criteria are the most relevant to your project(s). Once chosen, you’ll be able to download the obtained results by scrolling down at the bottom of the page and clicking on “Download results”.

You can contribute prices by using our API. If you want to contribute prices at scale, please get in touch with us at contact@openfoodfacts.org.

For legal and technical reasons, we don’t consider scraping prices from retailers’ websites as a valid way to contribute to Open Prices. We want to make sure that the prices we collect are accurate and up-to-date, and receiving scraped prices from contributors doesn’t allow us to do that.

Price scraping is a considered option in a future version of Open Prices, but it would be done by Open Prices itself so that we can have a proof of the price based on the HTML page.

Price information is of paramount importance to understand food systems. It’s a key factor in understanding the cost of food and to promote healthier diets. Opening price data is a way to make it easier for researchers, journalists, and citizens to have a better understanding of how food prices vary geographically and in time.

The Folksonomy Engine is a system that allows users to add custom tags, or properties, to food products in Open Food Facts, the world's largest open-food database. This lets people categorize and describe food in new ways, beyond the existing predefined properties.
