As one comedian here commented, I would like to know what happened to all the cows that were supposed to be in those meals.
Jokes aside, from what I read, a lot of the horse meat was from Romania, not France. As has been mentioned, it's the chemicals in the meat (not meant for human consumption) rather than the meat itself that is/should be the concern.
However, this should be good for local meat producers and butchers here though - hopefully people will go back to sourcing locally and help the local farmers and butchers that are disappearing from the high streets. Or turn more people vegetarian - that wouldn't be such a bad thing either.
