A Louisiana Senate committee rejected an emergency rule approved by the Louisiana State Racing Commission (LSRC) to lower the testing threshold level for phenylbutazone (Bute) from 5 micrograms per milliliter to 2 micrograms.

The Louisiana State Senate Commerce Committee took the action Jan. 20 after horsemen protested the manner in which the LSRC approved the rule. The Louisiana Horsemen’s Benevolent and Protective Association (HBPA) claimed the change isn’t an emergency, and therefore interested parties should have had time to comment.

"We’ve got no problem with the rule, and the last thing we want to do is interfere with any of the tracks in Louisiana," Louisiana HBPA president Stanley Seelig said in a statement provided by the National HBPA. "We just want the commission to do this the right way. Conduct a hearing, let people state their views. There’s no reason this was an emergency."

The lower testing threshold for the non-steroidal anti-inflammatory drug phenylbutazone, commonly called Bute, is among the model rules adopted by the Association of Racing Commissioners International in recent years. It is in the process of being adopted in various jurisdictions that haven’t already done so
