Poisoning and infectious diseases

Disease areas

We spend a great deal of time and effort ensuring that food premises are clean and hygienic to prevent them from causing food poisoning. We also investigate cases of food poisoning to try and find out what caused them and to stop them spreading.

Food poisoning is the most common, but we also investigate other illnesses such as dysentery, hepatitis and typhoid.

We trace the source, by interviewing both the people who are ill and their contacts, and try to ensure the diseases are not spread. This sometimes means we have to stop people going to work and children under five years old from attending school.
