Allergen control: keys to preventing cross-contamination in food plants

In the food industry, allergen control has evolved from a recommendation to a critical requirement. The accidental presence of traces, especially gluten, can have serious health, legal, and commercial consequences. 

Preventing allergen cross-contamination requires a comprehensive strategy that goes beyond basic hygiene measures.

At Roser Group, we help our clients implement solutions that ensure plant safety, from raw material intake to final product output.

Why allergens pose a critical risk

Food allergens such as gluten, lactose, nuts, or eggs affect millions of consumers. However, managing them is far from simple: in many cases, even minimal traces can trigger severe reactions.

Companies working with flour, confectionery, or snacks face major challenges when producing allergen-free alternatives. Batch separation or cleaning lines is not always enough, any unintentional contact can compromise product safety.

How to prevent cross-contamination at every critical point

Allergen cross-contamination occurs when a product comes into direct or indirect contact with unwanted traces. This can happen at various stages:

Flow and zone separation

Physically separating production lines, storage areas, and staff access points is essential. Ideally, separate facilities should be established for allergen and non-allergen products whenever possible.

Hygienic changing rooms: the first line of defense

Personnel movement must also be controlled. Designing changing rooms with segregated access, assigning exclusive workwear per line, and implementing hygiene systems such as hygiene stations prevent operators from becoming contamination vectors.
