One fourth of supermarket chicken samples has antibiotic-resistent E-coli.


The bacterium was discovered in packs of meat sold at Tesco, Sainsbury’s, Asda, Aldi, Waitrose, the Co-op, and Morrison's. Scientists from University of Cambridge tested products such as whole roasting chickens, diced breast meat and packets of legs, thighs and drumsticks, detecting ESBL E coli – resistant to many types of antibiotics on 22 of 92 samples.
