Their feed is contaminated, I feel sorry for them, nothing they can do about it.

Wow, what a blow!

Such a shame to have his runners taken out of the race by something he had no control over.

It was contaminated with Zilpaterol which is produced by Merck for increasing muscle in beef cattle. Not allowed in Europe but is in the USA.
