The Food Standards Agency (FSA) has published the latest results from its year-long survey into the presence of campylobacter in raw chickens, finding the presence of the bug in 73 per cent of those chickens tested.
Tesco has said it is "committed" to reducing the food poisoning bug campylobacter in poultry.
"Providing safe food is always our absolute priority," a Tesco spokesperson said.
"Whilst there is no simple solution to prevent its presence in raw poultry we have and will continue to work in close collaboration with our suppliers, scientists and relevant industry experts to make solid progress to tackle the problem at all stages of the supply chain."
As the Food Standards Agency finds the presence of campylobacter in 73% of raw chickens, here is what you need to know to fight the bug.
Every major supermarket tested had significant levels of the bug present on their raw chicken samples, the Food Standards Agency said.
