Chad Keenum, of The Plains, Va., has received a six-month suspension from the U.S. Equestrian Federation after two of his horses tested positive for gamma-aminobutyric acid (GABA), a banned substance, in excess of normal physiological levels.

True Colors tested positive at the Brandywine Valley Summer Series Horse Show (Pa.), June 23-28, 2015, and Vanderloo tested positive at the Loudoun Benefit Horse Show (Va.), June 10-14, 2015. Both horses were owned by Keenum at the time of the positive tests.

The Los Angeles Equestrian Center in Burbank, Calif., was placed under quarantine Nov. 3 after a horse displaying neurologic symptoms was confirmed positive for equine herpesvirus-1.

When heavy rainfall caused severe flooding in Louisiana, a number of people in the equine community stepped up to help the horses affected. 

On Aug. 12, Louisiana governor John Bel Edwards declared a state of emergency for the entire state. The rainfall had begun on Aug. 11, with some areas receiving up to to 20 inches total, and it resulted in floods in 20 different parishes in southeastern Louisiana. 

One horse in Palm Beach County, Florida, was euthanized May 13 after testing positive for equine herpesvirus-1. 

“The 18 other horses on the premises currently are clinically normal,” stated a release from the  Equine Disease Communication Center. “Biosecurity measures and twice daily temperature monitoring are in place. All states with traces have been notified. The Florida Department of Agriculture and Consumer Services will continue to monitor the situation.”
