Today I ordered sushi and there was a gel pad kind of thing under the box to keep it cool . But I touched it and there was stuff coming out from it and it sticked to by hand and I touched the sushi and eat it. I don't know what that ice gel pad had it was slimy and by touching it felt slimy and bubly and didn't looked bubly. I have heard that gel pad contain chemical that are toxic and also fatal like antifreezing and something but not sure. The restaurant said that it has chemicals like hydrogen benzoate and other things as well that they don't know. Please tell will it cause death or something serious??
