Proposed Changes to Rodenticides

In November 2022 the EPA announced proposed changes to the regulations surrounding the use of rodenticides. The registration review of rodenticides is completed every 15 years and assesses potential risk to humans or the environment during common use applications.

Most notably, the use of many products over 4 lbs will be restricted to application only by a licensed professional.

The Rodenticide Task Force has created an educational website to help readers navigate the many changes being proposed. To learn more about specific proposed changes visit:

A letter sent to request an extension to the public comment period was denied. The EPA is accepting public comments concerning these changes until February 13, 2023. The AHC is working closely with the Office of Pest Management Policy (OPMP), Ag coalitions, feed associations, and more. Potential concerns regarding increases in restricted use above 4 lbs of bait include pasture land and hay crop management, disease spread, and facility damage.

The AHC does not perceive commercial level use of rodenticides among members, and has not received comments from members concerning these proposed changes. It’s important to take the time to understand how these proposed changes may affect your own operations within and related to the industry.

If you have questions, concerns, or comments to submit about changes to these policies, we want to hear from you! Reach out no later than February 1st.

Top of the Rockies Alfalfa Cubes  Recalled for Botulism

A botulism outbreak in December 2022 affecting at least 98 horses and resulting in several dozen deaths and euthanasias has triggered an FDA recall of Top of the Rockies Alfalfa Cubes. This recall includes the date codes 111222, 111322, 111422, 111522, and 111622. The alfalfa cubes have been recalled by Manzanola Feeds of Manzanola, CO which distributes directly to feed stores and co-ops in 10 states.  

Symptoms of botulism include signs of neurologic illness such as difficulty eating or swallowing, stiff gait, weakness, colic, difficulty standing, and more. If you suspect a horse has eaten the recalled feed and is exhibiting any of these symptoms, call a veterinarian right away.

Botulism is a serious and deadly disease. If you identify recalled bags of feed or can’t be sure of the date codes of feed bags in your possession, do not feed them to your horse or any other animals in your care. In addition, it’s important to practice safe handling techniques when disposing of the feed and cleaning any feed containers.

Avoid handling the cubes directly and wear disposable gloves and a face mask while throwing them away. Throw them away in a secured container and place them in a covered trash can or dumpster no other animals can access. Follow disinfection protocols listed on the FDA website for cleaning any feed containers and surfaces the feed has touched. Wash your hands thoroughly after disposing of feed.
