In a release earlier this month, the U.S. Food and Drug Administration announced approval of Monovet 90, the first generic monensin product for use in cattle and goats. In the release, the FDA included a reminder that monensin is toxic and potentially lethal to horses.
This week, the FDA reissued the release, with added text to emphasize that monensin is safe for use in cattle and goats, and that “meat from cows and goats and milk from cows treated with Monovet 90 are safe for people to consume; the product does not pose any significant impacts to the environment."
FDA recommends mitigating user risk by taking appropriate safety precautions, such as wearing protective clothing, impervious gloves and a dust mask. Also, producers must take care to avoid any chance of horses being exposed to monensin through contaminated feeding equipment or access to medicated feed intended for cattle or goats.
Monensin is an ionophore, which is an antimicrobial not used in humans; therefore, use of this drug does not raise antimicrobial resistance concerns.
Monovet 90 is a Type A medicated article and will be available over-the-counter in 25 kg bags. It is approved for use in the manufacture of Type B and Type C medicated feeds. Monovet 90 is manufactured by Huvepharma EOOD.
