Study finds 20% of UK supermarket chickens contaminated

One in five supermarket chickens is contaminated with the food poisoning bacteria campylobacter, an investigation in Britain has found.

The study of chicken samples from nine supermarkets by the Which? consumer group found 18% were contaminated with campylobacter and 17% were contaminated with listeria, with 4% containing levels of the latter classed as “high” by the Food Standards Agency (FSA).
