The California Horse Racing Board has unanimously adopted a regulation that effectively bans anabolic steroids in horses running in the state, paving the way for the Breeders' Cup to be run steroid-free this fall at Santa Anita.

The board moved the anabolic steroids testosterone, boldenone, nandrolone and stanozolol into a higher classification, so that now, without exception, any steroid violation will result in the disqualification of the horse.

Under new penalties, violations could result in a minimum 30-day suspension.
