Presuming you mean meat I consistently dislike no matter if it's well prepared or in good condition: None. I would say beef and chicken but those were isolated instances and you removed them as options too.

Then... I don't know, every time I tried something else it turned out to be good. Once I had a codfish that wasn't well prepared. It was tough like a shoe sole and full of bones. But it didn't taste terrible, so I'm not sure if it's a suitable option.

ITT: Lots of things that aren't meat.

camel

Perch and Catfish are pretty awful. Catfish more for the texture. Perch just tastes bad.

Oyster. Anything with the consistency of snot that you're supposed to swallow without chewing isn't food. I can make my own salt water that tastes much less disgusting.

Venison, and for the same reason as lamb

I don't like muscles from the Puget Sound because they taste like it smells and I cannot get past that.

Alligator. Venison. Duck. Butterfish. Trout. Mussels.

Crocodile can be a bit hit and miss. Supposedly ‘tastes just like chicken’ but there was an extra flavour I can’t describe.

You said not lamb but lamb. Nothing will ever taste worse than the lamb steak I had from a high end Brazilian churrascaria once. It straight up had the taste and texture of poop. Thinking about it makes me gag.

That's also where I learned how much I hate filet mignon

An undercooked venison burger. I can't remember what it tasted like when I ate it, but coming back up it was very unpleasant

Cockroach (if that counts) and rat.
