R-CALF is urging the FDA to approve ivermectin to prevent New World screwworm

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.
