FDA Cautions Horse Owners Not to Feed Recalled Lots of Top of the Rockies Alfalfa Cubes Due to Reports of Illness and Death
FDA, in cooperation with state departments of agriculture in CO, LA, NM, and TX, is investigating cases of illness and death in horses.
The U.S. FDA is cautioning horse owners not to feed recalled Top of the Rockies alfalfa cubes with the date codes 111222, 111322, 111422, 111522, and 111622. Some of the alfalfa cubes have been reported to contain what appears to be fur and animal tissues, indicating that material from an animal or animals may have been incorporated into the cubes during alfalfa harvesting. Some people have reported a foul odor in some of the bags. Clostridium botulinum, the bacterium that causes botulism, is commonly present in decaying animal carcasses. Testing of the alfalfa cubes and other feed and tissue samples is in progress.
These alfalfa cubes were made by Manzanola Feeds of Manzanola, CO, and FDA has confirmed the firm distributes products to feed stores and co-ops in 10 states: AR, CO, IL, KS, LA, MO, NM, OK, TX, and WI. Further distribution may be possible, so it’s important to check the date code if you have this product.
FDA is aware of several horses in Colorado, Louisiana, New Mexico, and Texas who showed neurologic symptoms, and is working with state authorities to learn more. At least 45 of these horses have died or were euthanized due to declining health. Necropsies of some of the horses are underway or pending. At this time, it appears that Top of the Rockies alfalfa cubes was the only common food source among all of the cases.
This is an ongoing investigation and FDA will share additional information as it becomes available.
If you have Top of the Rockies alfalfa cubes with the date codes 111222, 111322, 111422, 111522, or 111622, or you can’t be sure of the date code of the products you have, do not feed them to your horses or any other animals. Throw them away in a secure container and place them in a covered trash can or dumpster so that no other animals can access them. Avoid handling the cubes directly and wear disposable gloves and a face mask while throwing the cubes away and cleaning any bins or containers where they were kept.
Attending veterinarians and state officials have reported that horses have shown symptoms of neurologic illness, including muscle tremors that rapidly progressed to the whole body, weakness, decreased tongue tone, agitation, and inability to stand. If you see these symptoms in your horse, seek immediate veterinary care.
These symptoms are consistent with botulism and many horses have been treated for suspected botulism. No human illnesses have been reported to date.
If you think your horse has become ill after eating contaminated food, call your veterinarian first. You can also report the illness to FDA through the Safety Reporting Portal or by calling your state’s FDA Consumer Complaint Coordinators. If possible, share the brand name and lot numbers of what your horse ate.
