An allergen is a substance which triggers an allergy, a series of reactions of the body’s immune system resulting from contact, ingestion or even inhalation of a food allergen.


A consumer with an identified food allergy has to avoid the consumption of any foodstuff containing the substance likely to cause more or less severe health impacts.


The frequency of food allergies and their consequences for consumers’ health led the authorities to adopt new information measures.


Any product containing allergens is subject to the adequate mandatory labelling.


Regulatory provisions

  • EU 1169/2011 “INCO” Regulation, relating to consumer information on foodstuffs, more specifically articles 9, 21, 44 and Annex II, about substances or products causing allergies or intolerances, among which labelling rules about allergens.
  • Decree No. 2015-447 of 17 April 2015 relating to consumer information on allergens and non-prepacked foodstuffs.


The DGCCRF (French General Directorate for Competition Policy, Consumer Affairs & Fraud Control) updated the hereunder listed food allergens in September 2015.

Regulation EC/41/2009 defined the thresholds for “gluten-free” products (20 mg/kg) and ‘’very low gluten’’ products (100 mg/kg). The advisable thresholds for other allergens are under discussion.

CARSO developed various analytical methods to analyse the whole range of  allergens:

•    Immunological methods (ELISA)
•    LC-MS/MS
•    PCR
