Happy Mouth bit manufacturer English Riding Supply has recalled approximately 3,400 Happy Mouth Wire Mouth bits, according to an alert from the U.S. Consumer Product Safety Commission.

"The steel braided wire in the mouthpiece that connects the bit on either side of the horse’s cheeks can become frayed, rusted, or worn, which can cause the bit to break," the alert read. "If this happens, the rider can lose control and fall from the horse." English Riding Supply has received four reports of bits that have broken and resulted in rider falls.

The alert indicated the products in question were sold July 2003 through April 2012. Model numbers, which can be found on the product label, included in the recall are 462172SS, 462177SS, 462181SS, 462184SS, 464123SS, 466898SS, 466904SS, and 467248SS.

"Consumers should immediately stop using these bits and return them to the retailer where purchased or return the bits directly to English Riding Supply for a refund," the release read
