Data sources
Every source we draw on, what its licence permits, and how we treat it. Sources marked share-alike are tagged on every record derived from them and are never mixed into our proprietary core.
FoodSignal editorial
FoodSignal's own workTechvora
- We import records:
- Yes
- We copy images:
- Yes
Records created or verified by FoodSignal staff, and contributions assigned to us under the contribution terms. The proprietary core.

U.S. Department of Agriculture, Agricultural Research Service. FoodData Central.
Public domain, so it can sit in the proprietary core. Provenance is still recorded even though attribution is not legally required. Generic reference foods are kept strictly apart from branded packaged products — a USDA generic nutrient profile must never be attached to a branded supermarket product because the names look similar.
Food Safety Authority of Ireland
Attribution requiredFood Safety Authority of Ireland
- We import records:
- No — reference only
- We copy images:
- No
Consulted for Irish allergen and labelling guidance and for food alerts. Marked import_permitted = false: it is a reference we read, not a dataset we ingest, until the reuse terms have been reviewed properly.
Regulation (EC) No 1333/2008 (food additives)
Attribution requiredEuropean Union
- We import records:
- Yes
- We copy images:
- No
© European Union, https://eur-lex.europa.eu, 1998–2026
The EU positive list for additives and the Annex I functional classes. FoodSignal cites it for what an additive is authorised to do, never for a safety opinion.
Regulation (EC) No 1924/2006 (nutrition and health claims)
Attribution requiredEuropean Union
- We import records:
- Yes
- We copy images:
- No
© European Union, https://eur-lex.europa.eu, 1998–2026
The legal conditions for 'source of fibre', 'high protein' and similar. Because these are the statutory tests, FoodSignal can state them as fact rather than opinion.
Regulation (EU) No 1169/2011 (food information to consumers)
Attribution requiredEuropean Union
- We import records:
- Yes
- We copy images:
- No
© European Union, https://eur-lex.europa.eu, 1998–2026
Source of the Annex II allergen list, the mandatory nutrition declaration, the salt/sodium conversion factor and the high-caffeine threshold. Reuse of EUR-Lex material is authorised under Decision 2011/833/EU; only the printed Official Journal is authentic.
UK front-of-pack nutrition labelling guidance
Attribution requiredDepartment of Health and Social Care / Food Standards Agency
- Licence:
- Open Government Licence v3.0
- We import records:
- Yes
- We copy images:
- No
Contains public sector information licensed under the Open Government Licence v3.0.
The low/medium/high thresholds FoodSignal uses for fat, saturates, sugars and salt. Voluntary UK guidance — labelled as such wherever it appears, and never presented as an EU or Irish requirement.
Open Food Facts
Share-alike — kept separableOpen Food Facts (association, France)
- We import records:
- Yes
- We copy images:
- No
Contains information from Open Food Facts, available under the Open Database License (ODbL).
Used to bootstrap coverage, not as a permanent dependency. Product facts are imported and tagged; images are never copied because they carry a different, stricter licence than the database does. Open Food Facts asks for an identifying User-Agent and rate-limits product reads.
