The Fédération Equestre Internationale (FEI) announced July 21 that three Swiss show jumping horses have tested positive for prohibited substances.

Samples taken at the CSIO5* at La Baule, France, on May 17 from the horse Nino des Buissonnets, ridden by Steve Guerdat, who won the Grand Prix on the day of testing, have returned positive for the banned substances codeine and oripavine and the controlled medication morphine.

Additionally, samples taken at the CSIO5* at La Baule on May 17 from the horse Nasa, also ridden by Guerdat, who finished third in the La Baule Derby on the day of testing, have returned positive for codeine and morphine. The horse’s sample also showed traces of oripavine, but not at a sufficiently high level for the testing laboratory to declare a positive for the substance.

Finally, samples taken at the CSIOY (Young Riders) in Deauville, France, on May 8 from the horse Charivari KG, ridden by Alessandra Bichsel, have returned positive for codeine, oripavine, and morphine
