Scientists from the School of Biology from the Australian National University took 281 samples from three major supermarkets and a butcher around Canberra.
In those chicken samples contaminated with the common bacteria E.coli, almost two thirds of the bugs were resistant to some form of antibiotic.
…Researchers were particularly concerned to find four samples resistant to fluoroquinolone antibiotics, which are banned from use in Australian food-producing animals.
It is a mystery, for the bacteria shouldn’t be able to gain resistance without exposure to the antibiotic. Scientists suggest some form of cross-contamination between the slaughterhouse and their testing, but only humans, cats and dogs receive fluoroquinolone antibiotics in Australia.
