The California Horse Racing Board (CHRB), citing feed contamination, has dismissed 48 positive tests for zilpaterol.

The feed contamination appears to have occurred in mid-February, with the first positive detected from a race run March 1. The CHRB ruled that the cases from March 1 to March 26 have or will be dismissed.

The CHRB said the contaminated feed has been identified, as described in a March 22 advisory, and horsemen are or should be aware of the contaminated feed. If trainers have removed the feed, residues of zilpaterol in horses should be eliminated by the end of March.

In the March 22 advisory, the CHRB said it concluded a number of sweet feed products containing a molasses base produced by Purina at its Turlock, Calif., mill contain zilpaterol, which is prohibited in racing. Zilpaterol is a beta-2 agonist used to promote weight gain in livestock. Association of Racing Commissioners International classifies zilpaterol as a Class 3 drug with a Category A penalty
