Still do in tons of places!

Sold overseas, absolutely. Domestically, it's been a more.. controversial subject. https://priceonomics.com/when-americans-ate-horse-meat/

Horse leather (shell cordovan specifically) was for years used to make police belts and holsters - it's heavier than cow leather and more supple.

It can still found in some places in France. It's quite good, a bit like beef with less fat.

I think you can buy a horse steak in most western countries, although most regular grocery stores don't carry it. You'd need to go to a butcher or a higher end store.

I bought a cut of horse steak in Norway around 2005. I haven't really looked for it since, so I don't know if they stopped selling it. It's often mixed into sausages as well, but labeled in a less obvious way.

Had....?
