Not defending McDonalds, really, but they apparently haven't used pinkslime in their products for a year now in the USA. I'm not sure about Canada, though, so you may want to look that up. They claim to never have used it in the UK or Ireland so that wasn't an issue over here. Thank God, we've had enough to deal with from mad cow disease and now imported horse/donkey meat. (Which again, McDonalds claim not to have been affected by the recent meat scandal.)
But shouldn't be an issue that it was there in the first place and no one stopped it?
