The California Horse Racing Board is particularly interested in Purina products from mid-February from Purina’s Turlock mill. If any licensed trainer or feed company has an unopened bag of any Purina brand from mid-February milled at their Turlock plant, please contact their local California Horse Racing Board investigator.
The California Horse Racing Board has been working with the California Department of Food and Agriculture on this issue. Purina and the California Department of Food and Agriculture may have their own statements. The purpose of this notice is to avoid positive tests for zilpaterol. Zilpaterol is a beta-2 agonist used to promote weight gain in livestock. ARCI classifies zilpaterol as a Class 3 drug with a Category A penalty.
