In a tragic incident, approximately 70 horses at Beutler and Son Rodeo Co. in Elk City, Oklahoma, have died after consuming feed suspected to be tainted with monensin, a drug toxic to horses but commonly used in cattle feed. The horses fell ill shortly after being fed, leading owners to panic as they witnessed the animals collapsing. The Oklahoma Department of Agriculture is investigating the situation and has collected feed samples for analysis while working with Kansas authorities to trace the source of the feed. Experts suggest that human error likely led to the contamination, as monensin is not typically found in equine feed. The emotional toll on the owners is profound, as many of the horses were considered family and had been raised from birth. Ongoing investigations aim to clarify the circumstances surrounding this devastating event.
