Proposed horse meat ban cites health concerns

"Horses are not bred for human consumption," Meehan said in a statement. "Horses are routinely treated with drugs over the course of their lifetimes that are toxic to humans if ingested."

Lawmakers argued that horses sold for food also experience "brutal and inhumane" conditions.

The last ban on slaughtering horses for consumption lapsed in 2011.
