CHRB Dismisses Positives Related to Contaminated Feed
The California Horse Racing Board, citing feed contamination, has dismissed 48 positive tests for zilpaterol, which is used in cattle to promote weight gain.
The feed contamination appears to have taken place in mid-February, and the first positive test for zilpaterol occurred from a race run on March 1. The CHRB has ruled that any cases that have occurred from March 1 – March 26 will be dismissed.
The Board ordered vendors on Wednesday to remove all feed produced at the Purina Mills facility in Turlock, California from California racetracks until the company can assure the CHRB that its products are not tainted. Feed containing zilpaterol was traced to the Turlock plant. Vendors are also prohibited from selling or delivering any feed “containing any prohibited drug” to California backstretches, according to a report from Daily Racing Form.
