Real Story investigates "superbugs" in food sold in the UK.
The programme reveals details of the results of a specially commissioned survey testing chicken from supermarkets and wholesalers for bacteria such as E.coli and Campylobacter.
Significant numbers of the chicken tested contained bugs resistant to the antibiotics regularly used to treat them, including some that were multi resistant to three or more antibiotics.
Real Story also exposes how some farmers ignore licensing laws that are meant to regulate antibiotic use.
And that means some farm animals can be given more and more antibiotics. Excessive use of antibiotics encourages bacteria to mutate and become antibiotic resistant.
While bacteria in meat is killed if the meat is cooked properly and hygienically, one in three people suffer from food poisoning every year.
Real Story talks to some serious cases, some still suffering long-term effects, and finds out what happens when the antibiotics given to people to make them better simply do not work.
