Allergens - analysis

Oats, almonds, apple and milk

The Swedish Food Agency has several accredited methods for analysing allergens. An allergic reaction may occur either as a result of someone eating a poorly labelled food product or due to contamination of a food.

The Swedish Food Agency receives samples on behalf of companies and tests them for allergens. The Swedish Food Agency also analyses allergens in cases of suspected allergic reaction. As a consumer, if you suspect that a foodstuff contains an undeclared allergen it is important to contact the competent authority, usually the local authority in the municipality in which the company/restaurant is located.

Accredited methods

The accredited methods used by the Swedish Food Agency to analyse allergens using enzyme immunoassay (EIA) testing are listed below.
