Cargill says it has stopped using an antibiotic for disease prevention in its turkeys that is also used in human medicine. The company says as of August first, the use of gentamicin was stopped for turkeys harvested for its two largest brands. However, the company says turkeys will still be treated with antibiotics for control and treatment of disease. Cargill says it’s making good on its promise to reduce its overall use of antibiotics in its turkey business and that products covered by this decision will be available starting next year.
