The signs and symptoms of a food allergic reaction may occur almost immediately after eating or most often within 20 minutes to 2 hours after eating. Rapid onset and development of potentially life threatening symptoms are characteristic markers of anaphylaxis.

Allergic symptoms may initially appear mild or moderate but can progress very quickly. The most dangerous allergic reactions (anaphylaxis) involve the respiratory system (breathing) and/or cardiovascular system (heart and blood pressure).

Common signs and symptoms

If you suspect a food has caused a reaction, avoid that food, talk with your doctor and have it investigated.  If you know you have a food allergy, then always avoid that specific food trigger.

If you, your child or someone you care for has a reaction to any food, seek medical advice.  If you are worried about a serious reaction, call an ambulance or go directly to hospital.
