So it seems the horse meat was imported to Ireland from Poland, where the horses were slaughtered in an abattoir owned by the parent company of the Irish meat processors. Horse meat wouldn't provoke the automatic "errgh" in Poland it does here, but isn't as popular as in, say, France. More to the point, if this implies the horses had been kept in Poland, they were probably agricultural horses - still a lot of horse-carts and even horse ploughing out there - rather than racing horses, as that's a pretty minor sport there, and so won't have been fed any of these dangerous race horse drugs. Then again, with the supply chain already spanning three countries, these horses could have been taken to the Polish slaughterhouse from Germany or elsewhere.
