KAW press release commending Compass USA's new policy. Charlotte, NC-based Compass USA, Inc., the second largest food service company in the United States, will require that its suppliers of pork and chicken not use medically important antibiotics as growth-promoting feed additives and that they report their overall antibiotic use to Compass USA. This policy is the first ever adopted by a major food company to restrict the purchase of pork with the goal of reducing antibiotic use.
