Analysis
What the administration claimed
The FDA issued an Emergency Use Authorization for Ivermectin Liquid for Horses to be used for short-term prevention of New World screwworm infestations in horses.
Claimant: U.S. Food and Drug Administration Agency press release (Acting FDA Commissioner quoted)
Agency or office: U.S. Food and Drug Administration
Context
Press release from the FDA (July 15, 2026) announcing an EUA in the context of the Trump administration's response to New World screwworm; specifies the product is for short-term prevention in horses, not treatment, and is authorized for use within 24 hours of birth or at initial wound care.
Evidence
This is an official agency action reported in an FDA press release. The EUA authorizes use of a veterinary ivermectin product in horses for short-term prevention of NWS myiasis under specified conditions. The authorization is time-limited (effective until revoked or HHS declaration terminated) and restricted to horses; the release also notes the product's 24-hour prevention window and that it is not for treatment of established infestations.
