What’s the worst food ever in your opinion

I have been to the Middle East and Central Asia and I was never a big meat eater until I came across a dish called “horse meat soup” and the meat was extremely dry and not only that but the flavor of it was horrible and it was a brownish grey color, the worst I have had was a dish in a small village in Kazakhstan called Beshbarmak which was horse meat noodles, the noodles were extremely salty and I thought it would have been better without noodles, the meat was extremely dry and I couldn’t eat it anymore.
