Chick-fil-A said in a statement it will begin using some antibiotics in its chicken, reversing its 2014 decision to use none.
The fast food company said it will now use "no antibiotics important to human medicine," but will use antibiotics intended for animals to treat sick chickens, beginning in spring of this year.
Chick-fil-A went antibiotic free in 2014, at a time when other chains such as Panera, Subway and McDonalds made similar pledges.
Chick-fil-A said it does not use fillers, artificial preservatives or hormones in its chicken.
