The call comes as new figures show that 44 per cent of people always wash chicken before cooking it – a practice that can spread Campylobacter bacteria onto hands, work surfaces, clothing and cooking equipment through the splashing of water droplets.

Campylobacter is the most common form of food poisoning in the UK, affecting an estimated 280,000 people a year. Around four in five of these cases come from contaminated poultry. The resulting illness can cause abdominal pain, severe diarrhoea and vomiting. In certain cases, it can lead to irritable bowel syndrome, reactive arthritis and Guillain-Barré syndrome, a serious condition of the nervous system. At its worst, it can kill. Those most at risk are children under five and older people.

As part of the call – which comes at the start of this year’s Food Safety Week – the FSA has written to production companies that make food programmes, asking them to ensure that people aren’t shown washing raw chicken on TV. The letter has been co-signed by all of the major food retailers.

FSA Chief Executive, Catherine Brown, said: "Although people tend to follow recommended practice when handling poultry, such as washing hands after touching raw chicken and making sure it is thoroughly cooked, our research has found that washing raw chicken is also common practice. That’s why we’re calling on people to stop washing raw chicken and also raising awareness of the risks of contracting Campylobacter as a result of cross-contamination.

"Campylobacter is a serious issue. Not only can it cause severe illness and death, but it costs the economy hundreds of millions of pounds a year as a result of sickness absence and the burden on the National Health Service. Telling the public about the risks and how to avoid them is just one part of our plan to tackle Campylobacter. We are leading a campaign that brings together the whole food chain, which includes working with farmers and producers to reduce rates of Campylobacter in flocks of broiler chickens and ensuring that slaughterhouses and processors are taking steps to minimise the levels of contamination in birds. We are committed to acting on Campylobacter and providing safer food for the nation."

The survey commissioned by the FSA found that levels of awareness of Campylobacter are well below that of other forms of food poisoning. More than 90 per cent of the public have heard of salmonella and E.coli, whereas only 28 per cent of people know about Campylobacter. Furthermore, of the people who have heard of Campylobacter, only 31 per cent of them know that poultry is the main source of the bacteria.

The most cited reasons people gave for washing chicken were the removal of dirt (36 per cent), getting rid of germs (36 per cent) and that that they had always done it (33 per cent).

Ann Edwards, 67, from Hertfordshire contracted Campylobacter in 1997 and is still living with the consequences today. She said: 'After contracting Campylobacter poisoning, I was ill for a week before being admitted to hospital with bladder failure. I couldn’t eat and was so de-hydrated that I lost almost two stones in weight. Shortly after, I developed Guillain-Barré syndrome which left me paralysed from the chest down. I was in hospital for seven weeks and even now – 17 years later – I have no movement in my toes and rely on a walking stick. Physically, it has been the worst thing that has ever happened to me. I urge anyone who is handling chicken to take care and follow the advice given by the Food Standards Agency.'
