Texas Ag Commissioner Urges FDA to Approve Feed-Based Ivermectin for Screwworm Fight

Texas Agriculture Commissioner Sid Miller is urging the Food and Drug Administration to authorize ivermectin in medicated livestock feed as the New World Screwworm continues spreading across Texas. Miller says while the FDA recently approved injectable ivermectin for emergency use, feed-based treatment would allow producers to protect entire herds more efficiently and provide a practical way to help protect free-ranging deer and other wildlife. “Injectable ivermectin was an important first step, but it's not enough,” Miller said. “Feed-based ivermectin would allow producers to protect entire herds quickly and efficiently with far less stress on both livestock and producers.” The request asks the FDA to issue an emergency authorization, so feed manufacturers can begin producing medicated feed immediately. Miller says an "all-of-the-above" approach—including sterile flies, surveillance, inspections, injectable treatments, and feed-based ivermectin—is needed to stop the parasite before it causes even greater losses for livestock producers and threatens the nation's food supply.
