Ongoing global coordination efforts also do not track the movement of antibiotics intended for veterinary use in global trade. The UN Comtrade data track antibiot¬ics (code 2941), but only some classes of antibiotics are separated out in the data, and one cannot distinguish whether antibiotics are destined for human or veteri¬nary use. Along with changing the nature of high-den¬sity animal production, collaborative research efforts to find alternatives to the non-therapeutic use of antibiot¬ics are needed. The OIE and the U.S. President’s Council of Advisors on Science and Technology (PCAST) have called for investing in the fundamental research needed to develop alternatives to antibiotics in agriculture.32
