R-CALF USA is calling on the FDA to approve ivermectin to help protect livestock from the possible spread of New World screwworm in the U.S.
The group says that feed-grade ivermectin is a proven tool to protect domestic herds and wildlife, especially in southern border states.
They highlight the success of the drug in limiting the spread of cattle fever tick.
“The potential impact on the United States livestock markets would be immensely negative if an actual case of New World screwworm was identified in the USA. Until an adequate response with gamma ray irradiation of male screw worm flies can be implemented, the feeding of ivermectin is a very real defense.”
The request follows false reports that New World screwworm was found in Missouri. That claim caused a downturn in cattle futures markets and is now being investigated by the state of Missouri.
The spending bill keeps animal health and traceability funding in place while trimming several other USDA accounts.

With the Farm Bill now in the Senate’s hands, industry groups say the stakes are high—and timely action could be critical for producers navigating a difficult economic environment.
The Texas Department of Agriculture confirmed a New World Screwworm case about 119 miles from the Texas border, near Zapata, Texas, and north and west of the Rio Grande Valley.
