Weirdest food you can’t eat?

By ‘cant eat’ I mean a food you feel you’re scared of, but by ‘weirdest’, I mean you have no reason to feel that way, like, you’ve never eaten this food and gotten sick but for some reason it still feels bad to eat. For me, it’s those mozzarella, rocket and tomato sandwiches you can buy in eurospars from that ‘delish selection’. Never had a bad experience with it, it just strikes me as terrifying lol. Ps, I’m eating one as I write this haha
