Allergens in Schools: Identifying Risks and Preventing Exposure

Children with allergies can be exposed to allergens in many different ways throughout the school day. While food is the most common trigger, allergens can also be found in activities, classroom materials and shared environments.

It is essential that school staff understand where these risks exist and how to reduce the likelihood of accidental exposure.

Food Brought from Home

One of the most common sources of allergens in schools is food brought in from home. Packed lunches, snacks and treats may contain:

• Peanuts and tree nuts
• Milk
• Eggs
• Sesame

Younger pupils may not fully understand the risks and may share food with friends, which can lead to accidental exposure for those with allergies.

School Meals and Catering

School meals can also present risks if ingredients are not clearly identified or managed.

To reduce risk:

• Catering staff must be aware of pupils with allergies
• Allergen information should be clearly communicated
• Unsafe foods must be avoided for affected pupils

Strong communication between catering teams and school staff is vital to ensure pupil safety.

Classroom Activities and Learning Materials

Allergens can also appear during classroom activities, including:

• Cooking and baking lessons
• Food-related projects
• Science experiments

Even craft activities may involve hidden allergens such as:

• Flour
• Milk powder
• Egg-based materials

Staff should always check materials in advance and consider safer alternatives where necessary.

Special Events and Celebrations

School events can introduce additional risks. These may include:

• Birthday treats
• Classroom parties
• Cultural celebrations
• Fundraising events such as bake sales

Food brought in by pupils or parents may not always be clearly labelled, increasing the risk of accidental exposure. Careful supervision and planning are essential during these occasions.

Allergens Beyond the Classroom

Allergens are not limited to the classroom. They may also be present during:

• School trips
• Breakfast clubs
• After-school activities
• Sports events

Staff supervising these activities must:

• Be aware of pupils with allergies
• Ensure emergency medication is accessible
• Have access to allergy management plans

Reducing the Risk of Allergen Exposure

By understanding where allergens may be present, staff can take practical steps to reduce risk and keep pupils safe.

• Supervise pupils carefully
• Promote good communication
• Discourage food sharing
• Check ingredients and materials in advance
• Ensure emergency procedures are in place

These measures help create a safer school environment where pupils with allergies can learn and participate with confidence.
