Causes and symptoms
The NHS website explains food allergy causes and symptoms.
Information for consumers
Any prepacked food or drink sold in the UK must clearly state on the label if it contains certain ingredients. The Food Standards Agency explains your food allergy rights - what the law means for you.
If you think that a food product has been labelled wrongly, report this to Trading Standards at Warwickshire County Council.
Unpackaged food and eating out
The NHS website contains advice on eating unpackaged food for people with food allergies.
Information for businesses
The Food Standards Agency has produced guidance for business.

Small business producing loose foods
If you are a small or medium sized business that makes or sells loose foods you need to know what allergen information you must give to customers.
