The Food Standards Agency (FSA) have published a report reviewing the current state-of-the-art of allergen testing methodologies and the remaining challenges.
The work combined a critical literature review of testing methods with assessments of allergen proficiency testing data and included consultations with stakeholders from the food industry, and industry experts.
The aim is to find a suitable harmonised testing protocol that facilitates allergen risk management. Suitable workflows outlining recommended testing protocols are presented for priority allergens to provide a resource for compliant testing and incident management.
Estimates of the cost of setting up new testing laboratories to support allergen workflows are also included, as well as the cost of testing by established laboratories.
