FSIS upgrades IMPROVEST status from Notice to Directive

Published on: Oct 31, 2013

The U.S. Department of Agriculture's Food Safety & Inspection Service (FSIS) has issued a directive regarding on-farm protocols for using IMPROVEST (gonadotropin releasing factor analog - diphtheria toxoid conjugate). This protocol accreditation helps to ensure operational consistency for packers and their producer suppliers who adopt IMPROVEST that product protocols are comprehensive and will remain stable over time, according to Zoetis.

The previous FSIS "notice" acknowledged that hogs presented at harvesting facilities with the IMPROVEST quality assurance certificate are to be classified as barrows; and therefore, do not warrant testing for off odors during inspection. The classification change to "directive" signals that protocols for using IMPROVEST are no longer subject to annual review, although Zoetis will continue to audit and refine those protocols as necessary.

"It's important that our processes for using IMPROVEST meet the highest standards on the farm and at the processing plant," said Gloria Basse, Vice President, U.S. Pork Business Unit, Zoetis. "As we continue to work with packers on processing pigs raised using IMPROVEST, this FSIS status upgrade further validates IMPROVEST as a production option for the entire pork industry."

IMPROVEST is approved by the U.S. Food & Drug Administration for the temporary immunological castration and reduction of boar taint in intact male pigs intended for pork. IMPROVEST had been under FSIS notice classification since January 2013.
