Food allergies and intolerances pose significant challenges for consumers, food manufacturers, and regulatory authorities. Despite affecting a relatively small portion of the population, the impact on human health can be severe. This is why organizations like EFSA and FDA mandate proper allergen labeling in food products to mitigate health risks. Undeclared allergens are a leading cause of food product recalls in the EU and the USA.
Undeclared (on label) or unexpected allergens (cross-contamination) present a major threat to food product’s safety. Adequate control of allergens by operators is crucial to:
Food manufacturers need to conduct thorough risk assessments, utilize reliable testing services, and employ knowledgeable experts in national and international allergen regulations.
Producers, manufacturers, packers and distributors of food products or ingredients have the obligation to declare:
any ingredient or processing aid listed in Annex II or derived from a substance or product listed in Annex II causing allergies or intolerances used in the manufacture or preparation of food and still present in the finished product, even if in an altered form.
Regulation EU 1169/2011

Accurate and reliable analytical assessment of allergens is crucial for various purposes, including:
Mérieux NutriSciences offers qualitative and quantitative testing methods, utilizing cutting-edge technologies such as PCR, ELISA, and LC-MS/MS. Regular Ring and Proficiency Tests guarantee the highest level of precision when conducting analytical determinations.
ELISA detects allergenic proteins, while PCR reveals DNA from food allergens. These routine techniques, continually optimized by Mérieux NutriSciences’ R&D division, are effective across various matrices.
Mérieux NutriSciences proposes accredited tests, with ongoing efforts to extend accreditation to additional targets and matrices. The portfolio covers allergen analysis in food, surfaces, and environmental samples (accreditation ISO17025).
Thanks to our portfolio of testing technologies and solutions, we support our customers with dedicated services for consistent food allergens management:
In recent years, food producers have taken numerous actions to manage allergen risks, particularly through Hazard Analysis and Critical Control Points (HACCP)—a system for detecting, assessing, and managing food safety risks. This involves establishing a process to manage raw materials, flows, and other factors, requiring the active involvement of company personnel. Audits, process validations, and monitoring plans are essential components of this system.
While testing is integral, it alone is insufficient to minimize risks associated with allergens. Mérieux NutriSciences goes beyond testing by conducting audits and implementing training programs for employees, assisting in the development of a comprehensive control plan for allergen risk management.
