Perdue, the 4th largest poultry producer in the US, 2 years ago stopped feeding chicks the antibiotic gentamicin. Antibiotics in animal feed, used to stimulate growth and ward off illness, contribute to antibiotic resistance in humans, making so-called superbugs more virulent.
Congress has been trying to ban outright or curb antibiotic feed use since 1977. In 2011, the FDA opted for voluntary antibiotic self-regulation. Antibiotic feed use surged between 2009 and 2014.
Perdue bucked the trend. Today, 2/3 of its poultry get no antibiotics. The 1/3 that does is getting it out of health concerns, not as a growth stimulant.
