Mr. Brendan Gleeson:

My understanding is, racing does not exclude a horse from the food chain. What excludes a horse from the food chain is the potential that it might have received certain medicines during its career. Of course, it is lawful, and Mr. Blake can correct me if I am wrong, it is lawful to slaughter horses, including thoroughbreds and thoroughbreds that have raced, but if they have been administered with certain kinds of medicaments they cannot be slaughtered for consumption.
