What is the problem?
On December 17, 2022, the U.S. FDA cautioned 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.
