Nearly three-quarters of supermarket chickens are contaminated with the potentially deadly bug campylobacter, according to a year-long study by the Food Standards Agency (FSA).

The watchdog is now putting pressure on supermarkets to take action after finding that all the major retailers failed to reach industry targets for reducing rates of campylobacter.

Some 19 per cent of the contaminated chickens were found to contain the highest rate of the bug, which is responsible for an estimated 280,000 cases of food poisoning a year.

The FSA tests found that Asda had the highest rate of contamination in its fresh whole chickens at 80 per cent, followed by the Co-op with 78 per cent, Morrisons with 76 per cent, Waitrose with 74 per cent and Tesco and Marks and Spencer with 67 per cent.

Individual figures for Lidl, Aldi and Iceland are not available because their market share was not considered large enough, based on 2010 retail figures.

Kevin Hargin, the FSA’s head of disease control, said: “This is the FSA’s number one food safety priority, we’re taking it very, very seriously.

“This is the single most common cause of food poisoning, more than Salmonella and Listeria. Salmonella and Listeria might be more serious but this is certainly much more common.

“All of the results are quite disappointing, we didn’t see any significant reductions.”

He added that tackling the spread of the bug was “complex” and supermarkets must make changes throughout the whole production line, from farming to transport and packaging.

While none of the major retailers hit industry targets during the FSA investigation, the food watchdog said new internal case studies by Marks & Spencer, Morrisons, the Co-op and Waitrose based on more recent samples found a fall in contamination levels.

Mr Hargin said: “If some retailers can do it then others should be able to follow suit.

“I think consumers will be concerned and rightly so, we don’t think consumers should be bearing the brunt of the risk.

“We’re continuing to put pressure on the industry to ensure they continue their work with interventions.”

Consumers are most likely to pick the bug up through cross-contamination in their kitchen or from eating chicken undercooked.

However, because of a delay in symptoms, they may not realise the illness is caused by their fresh, shop-bought chicken, Mr Hargin added.

In serious cases, contracting the bug from highly contaminated poultry can be fatal.

Dr Georgina Manning, an expert on campylobacter at Nottingham Trent University, said: “Humans become infected when we eat chicken that has been undercooked or we contaminate kitchen surfaces or other foods during the handling of chicken.

“It is very unpleasant, with symptoms such as abdominal pain and diarrhoea. In most cases it lasts for just a few days and no treatment other than oral rehydration is necessary. However, in the very young and people who may have a weakened immune system, the symptoms can be more severe and antibiotic treatment or hospitalisation may be needed.

“In order to reduce the levels of campylobacter in chicken the whole of the food chain needs to be considered. Controls on the farm to prevent the bacterium entering the chicken flock are important, along with packaging and labelling to protect and advise the consumer that there is no need to wash the chicken, as this is a major cause of cross contamination in the kitchen.”

A second year of testing will begin this summer to measure the impact of interventions being introduced by the industry to tackle campylobacter.

More than 4,000 samples of fresh whole chickens and packaging from large UK retail outlets and smaller independent stores and butchers were tested.

​​​More about ​​​campylobacter

​• ​​Campylobacter is a bacteria that is the most common cause of food poisoning in the UK. It is thought to be responsible for more than 280,000 cases of food poisoning a year, according to the FSA.

​• It is usually found in raw or undercooked meat, especially poultry, and less often in unpasteurised milk or untreated water. About four in five cases come from contaminated poultry.

How can I avoid campylobacter poisoning?

To avoid the spread of campylobacter in your kitchen, follow this advice: ​

​• Cover and chill raw chicken Cover raw chicken and store at the bottom of the fridge so juices cannot drip on other foods and contaminate them with food poisoning bacteria.

• ​Don’t wash raw chicken Thorough cooking will kill any bacteria present, including campylobacter, while washing chicken can spread germs around the kitchen by splashing. ​​• ​Wash hands and used utensils Thoroughly wash and clean all utensils, chopping boards and surfaces used to prepare raw chicken.

​​• ​Wash hands thoroughly with soap and warm water after handling raw chicken. ​​

• ​Cook chicken thoroughly Make sure chicken is steaming hot all the way through before serving. ​​

• ​Cut into the thickest part of the meat and check that it is steaming hot with no pink meat and that the juices run clear.
