Food Allergen symptoms: How soon do they appear after eating?

In the UK, around two million people suffer from various food allergies and intolerances – these are only the diagnosed cases, so the actual figure is predicted to be much higher. Most food allergen sufferers know the signs, symptoms, and how soon after eating they appear, but do you?

Usually, food allergy symptoms appear within a few minutes of consuming an allergen, although the symptoms may take up to a couple of hours to appear.

There are many different food allergen symptoms to be aware of, such as – rashes and hives, itching and tingling in the mouth or throat, difficulty swallowing, swelling of the mouth, throat, and face, trouble swallowing, shortness of breath, nausea, vomiting, abdominal pain, diarrhoea – and more. Some people may develop a severe allergic reaction known as anaphylaxis, which can be life-threatening. Don’t hesitate in calling 999 if you think someone has the symptoms of anaphylaxis.

Food allergies can have extremely serious consequences for those who consume food to which they are allergic, and for the business that serves that food to them. Staff in food-related businesses across all sectors should fully understand these risks and how to apply due diligence to minimise them.
