Marks and Spencer has recorded the highest Campylobacter in chicken results in the most recent quarterly figures reported in the United Kingdom.
The newest data covers April to June for nine retailers on Campylobacter in fresh, shop-bought UK-produced chickens.
For Marks and Spencer, 5 percent were in the maximum category in April, 9 percent in May, and 9 percent in June based on a sample of 376 chickens taken from store shelves across the United Kingdom. This compares to 2 percent above 1,000 CFU/g in January, 3 percent in February and 4 percent in March based on tests of 292 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.
Waitrose has not updated its results from the first quarter of this year or provided them to Food Safety News when asked to do so. Levels at the supermarket for the previous quarter were zero percent in the above 1,000 CFU/g category.
Results of chickens in the highest contamination bracket went up for all other retailers except Tesco.
