According to Regulation 1169/2011, substances or products causing allergies or intolerances listed in Annex II must be labelled.
These substances include crustaceans, eggs, fish, peanuts, soybeans, milk, celery, mustard, sesame seeds, lupines, molluscs and certain nuts.
In its notice 24-2017, the Scientific Committee of the FASFC proposed to use the lower limit of the 95% confidence interval of ED05 (Dose triggering an allergic reaction in 5% of a sensitive population) as the reference dose for the risk assessment of ingestion of allergenic foods.
The following reference doses (expressed in mg of protein allergenic food) are recommended by the Scientific Committee for Risk Assessment:

Food allergens Proposed Reference Dose (mg of protein) Allergen concentration based on proposed reference dose (mg food protein allergen / kg)
Portion 25g Portion 400g
Arachid (peanut) 1,1 44 2,8
Milk 1,2 48 3
Egg 0,3 12,4 0,8
Hazelnuts 0,5 20 1,3
Nuts 0,5 20 1,3
Cashew nuts 0,6 24 1,5
Other nuts 0,5 20 1,3
Soybean 2,9 116 7,3
Wheat (and all cereals containing gluten) 1,3 52 3,3
Mustard 0,1 4 0,3
Lupin 4,5 180 11,3
Sesame seeds 0,4 16 1
Shrimps and prawns 12,1 484 30,3
Other crustaceans

At present, there is insufficient bibliographic data to establish a reference dose for crustaceans other than shrimps, molluscs, fish and celery.
The reference doses proposed in this opinion do not concern allergens that have been added as ingredients. In this case, the regulations require their labelling.
These doses should not be used as limits to conclude that a product is “free” from a specific allergen.

Know that your Phytocontrol laboratory is able to look for proteins in the following allergenic foods: Milk, Egg, Soya, Cereals containing Gluten and Crustaceans.
