Folks watching The Belmont Stakes this weekend got a shocking reality check after the race, in the winner's circle as the trophy was being presented when a PETA representative whipped out a sign demanding a ban on dopers in horseracing.

Readers of The PETA Files already know that Doug O'Neill, the trainer of Kentucky Derby and Preakness winner I'll Have Another, who scratched at the last minute, has a shameful record of illegally drugging horses, but nine out of the 10 trainers of the remaining contenders have violated drug regulations, too, including Michael Matz, the trainer of Belmont Stakes winner Union Rags.

It's time for racing fans to face up to the seamy practices that they're enabling—and how they're harming horses in the process. Of course, the problem goes far beyond The Belmont Stakes: Only two of the top 20 trainers in the U.S. last year had never been cited for a drug violation.

What You Can Do

Horse racing's dirty secret is out, and it's time for the dopers to get the boot. Please contact your members of Congress and ask them to support the Interstate Horseracing Improvement Act of 2011, which would prohibit the use of performance-enhancing drugs and expand drug-testing requirements at all races.

In 2002, the 1986 Kentucky Derby champ, Ferdinand, was slaughtered after his breeding days in Japan were done.

Fast-forward to 2009: Two more horses, Charismatic and War Emblem—Kentucky Derby champs from 1999 and 2002 respectively—may also face slaughter as their usefulness to breeders comes to an end.

This upcoming Belmont Stakes marks the 10th anniversary of Charismatic's tragic breakdown.

After breaking his leg in the 1999 Belmont, Charismatic was sold to breeders in Japan. His value as a breeding stallion has dropped dramatically (to approximately US$5,000), and he has been moved to the lowest-ranking of breeding farms.

War Emblem was sold for $17 million and hauled off to Japan to become one of 33 stallions used for breeding at the Shadai Stallion Station. Despite the use of steroids, hormones and psychological measures, he has refused to breed with most mares.

Just a few years ago, horse-racing fans cheered as Charismatic and War Emblem ran away with top prizes at the Kentucky Derby and Preakness Stakes. Now, PETA's most recent undercover investigation shows what could be in store for these once-celebrated stallions and thousands of other horses sold into the Japanese thoroughbred industry.

Each year in Japan, more than 20,000 horses, including many horses once used for racing, are slaughtered for dog and human food. This video shows the slaughter of a young thoroughbred. As stated in the New York Times, "The video is disturbing. It shows in graphic terms what happens to the unfortunate thoroughbreds who become spare parts in a contracting industry."

You can blame the U.S. horse-racing industry for the carnage. It routinely breeds tens of thousands of "surplus" thoroughbreds every year, then sells thousands of them to breeding facilities in Japan. More than 2,000 U.S. thoroughbred horses and breeding mares have been shipped to Japan since Ferdinand was slaughtered in 2002.

Just last year, Americans watched in horror as racing filly Eight Belles suffered fractures to both her front ankles and was euthanized just moments after running the Kentucky Derby. How can anyone not be disgusted by the shuffling of thousands of horses off to Japan and into slaughterhouses?

Join us in defending former Derby and Preakness champs Charismatic and War Emblem—and thousands of other thoroughbreds. Demand limits on breeding and a ban on the export of horses to Japan.
