Doctors say there may be a link to the antibiotics given to chickens and a serious infection found in women.
New evidence suggests that the drugs have created a new strain of e-coli that is super resistant to antibiotics.
Doctors say the e-coli strain is causing painful and long-lasting bladder infections in women.
And physicians are struggling to find treatments.
The chicken industry disputes the research and says it believes it's unlikely this antibiotic superbug comes from poultry at all.
