ARDEN HILLS, Minn. (Apr. 3, 2013—Today the California Horse Racing Board lifted its ban on certain Purina feed products and is permitting feed produced on or after March 27 at the Turlock plant on the California racetracks. This action is based on product testing results from independent laboratories and other actions taken by Purina.
Previously trace amounts of zilpaterol had been found in some Purina and Country Acres horse feed produced at the Purina plant in Turlock, Calif. Zilpaterol is a beta—adrenergic agonist used to promote weight gain in cattle and is banned in horse racing and many other competitive horse events. Purina does NOT use zilpaterol in any plant. Our investigation has revealed that small amounts of zilpaterol were included in a single ingredient supplied by a vendor to the Turlock plant in February. Purina and Country Acres products produced at any other Purina plant were not impacted and can be used without restriction.
We recommend competitive horse owners competing at events where drug testing occurs stop using Purina or Country Acres feed produced between Feb. 14 and March 26 at the Turlock plant. Competitive horse owners should contact their feed dealer for replacement product.
We have not had any reports of health issues caused by zilpaterol and don’t anticipate any given the low levels detected in the feed.
Horse owners should refer to the lot number (located on the bottom seam tape of the bag) to determine where and when feed was made. Products manufactured at Turlock will have the letters “TRL” in the date code. Date codes are formatted as follows: Example 3MAR15TRL1
3=Year (2013) / MAR= Month / 15=Day of Month / TRL = Plant Code (Turlock) / 1 = Shift Code
