Marks and Spencer has again recorded the highest Campylobacter in chicken results in updated quarterly figures from the United Kingdom.
Campylobacter is the most common cause of bacterial food poisoning in the UK and the dose needed to make people sick can be as low as a few hundred cells. Marks and Spencer is the only retailer to publish data showing the percentage of chickens contaminated at 100 to 1,000 CFU/g and at under 100 CFU/g.
Contamination figures published by the retailer went down as the quarter went on. The latest data covers July to September 2021 for nine retailers on Campylobacter in fresh, shop-bought, UK-produced chickens.
The Food Standards Agency (FSA) maximum level is 7 percent of birds with more than 1,000 colony forming units per gram (CFU/g) of Campylobacter. Marks and Spencer results were also above this limit in May and June 2021.
