Allergen Control

For consumers, manufacturers and public health authorities, Food allergies and intolerances are a major area of concern. Though only a small portion of the population gets affected but the health implications are very serious. This is a major reason that EFSA and FDA stipulate proper labelling of the allergenic ingredients. The presence of allergens in food is the predominant reason for product recalls from the market.

Analytical testing is very critical in monitoring-verifying- validating for food safety and quality programs. Validation of processes like cleaning and product changeover procedures should embrace environmental samples (e.g. rinsing water, swab) as well as product testing. The presence of allergens on product contact surfaces inside the production plant can be monitored using Swabs.

Advanced allergen control programs

In the last few years food manufacturers across the globe have started responding to allergen risks. The allergen risks are detected through HACCP (hazard analysis, critical control points a system of detection & assessment & management of hazards involved in food safety. This system requires to setup the accurate and systematic management of raw materials, flows and other factors which necessitates the involvement of manpower as well as the implementation of proper auditing, process validation and monitoring plans.


Testing is just one vital component of minimizing allergen risks. Through audits and training programs for employees, in accordance with client TNTH can help develop a control plan for allergen risk management.
