FDA Greenlights Emergency Generic Drug to Halt New World Screwworm in Cattle
· Texas Border Business

The U.S. Food and Drug Administration (FDA) has granted Emergency Use Authorization for Bimectin (ivermectin) injection to prevent New World screwworm infestations in cattle. This treatment is effective when administered within 24 hours of birth, during castration, or when wounds appear. However, it is not approved for use in lactating dairy cows or calves intended for veal. The FDA emphasizes the importance of following the 35-day slaughter withdrawal period to ensure food safety. Bimectin is available over the counter and is a generic version of Ivomec, previously authorized for similar uses in cattle.
