I'm sorry to the horse lovers here.
While it is scary, we have all may have already eaten horse meat. (google: Aldi horse meat)
If you eat anything pre-prepared odds are higher. I swear that beef is not what is in Ravioli, lol.
I have eaten deer, buffalo, squirrel, and whatever dad could bring home for food. (Buffalo is sold in the local supermarket, not that I buy it, but a friend only buys it for making chili.) Deer is very lean, and much better for us than beef, so is buffalo, believe it or not, I suspect horse would be too. I'm not going to intentionally eat horse meat, but cannot be sure it is not already in some foods, not just in France or from France, or Asia.
Watched a show last night that used moose meat. New Scandinavian Cooking on PBS.
I don't want to think of horse farms as being for food supply, but we do have cow farms, chicken farms, turkey farms, fish farms, buffalo farms, and it goes on. I guess if it is properly inspected, it should be safe for consumption.
Do we need another meat source? I don't know, but the prices of meat are so high now anyway, I just buy dried beans and rice, so, it may not make much difference and the market may be slim.
Again, so sorry for horse pet owners. I don't ever want to have to eat dog, cat, or rat either, but if life demands such things, it will happen.
