The Pasadena Tournament of Roses has canceled its annual horse show, Equestfest, because of an outbreak of equine herpes virus.
The show was scheduled for Dec. 30 at the Los Angeles Equestrian Center in Burbank.
But the center was quarantined last month after vets found 13 cases of the virus, EHV-1, which can cause neurological and respiratory disease and foal death.
Ttournament officials couldn't find a replacement venue in time and had to cancel the show for the first time in 17 years, according to the San Gabriel Valley Tribune.
However, the outbreak won't keep equestrian units out of the Rose Parade.
The tournament plans to follow anti-infection protocols by limiting contact between horses during the Jan. 2 parade and making sure they don't share water or equipment.
