Food safety and food poisoning
Causes and symptoms of food poisoning

Investigating causes of food poisoning and food-borne illness
In some cases your GP is legally required to notify both us and the Health Authority if you visit them with a case of food related infectious disease. In the interests of public health we investigate cases of food related infectious disease to:
- find the cause, is possible
- minimise the risk of others being infected
- see if individual cases are linked to a larger outbreak
- investigate commercial food producers that may be linked to cases or outbreaks
For more information please contact the Public Health and Regulation team.
Food allergies and intolerances
A food allergy is when the body's immune system reacts unusually to specific foods. Although allergic reactions are often mild, they can be very serious.
A food intolerance is not the same thing as a food allergy.
