Public Analysts provide a crucial public protection service, ensuring that the food we eat, the water we drink and the products we buy are safe. They work in several areas including food and consumer safety, animal feed, workplace safety, water and environment, and emergency planning.

Using their expertise in chemical analysis and the interpretation of results, Public Analysts help local authorities to enforce UK and EU regulations. They also provide scientific advice during forensic investigations and may be called upon as an Expert Witness to give evidence in a court of law.

Highly skilled analytical scientists, Public Analysts are competent in chemistry, biology, microbiology, microscopy and the law relating to food, water, agricultural fertilisers and feeding stuffs.

As well as impeccable problem solving skills, a Public Analyst must be able to deal with high pressure situations and be able to communicate complex issues to a non-scientific audience.
