The number of food poisoning cases has dropped by 17,000 in the past four years, a survey has found.

The survey by the Food and Drink Federation to mark the start of Food Safety Week found that the number of cases had fallen from 96,000 to 78,921.

Nearly 90% of Britons wash their hands after handling raw meat and 81% wash their hands before preparing food, the survey said.

National Food Safety Week runs until June 19 and will focus on raising awareness of how hands can spread germs.
