The piece of fish was a breaded pollock patty in a TV dinner. The package says "Cook Thoroughly" and tells you to use a food thermometer to make sure it's done, which makes me think the fish was raw to begin with. I cooked it on the longest setting advised on the package (5 min 30 seconds) but it was still cold in the center. I only swallowed a small bite that was actually cold, but now I'm scared I'll get food poisoning. I know people eat raw sushi all the time but I never have. Ugh.

More info: the TV dinner was a Healthy Choice Lemon Pepper Fish meal. It doesn't say whether it's pre-cooked or not. All my other non-meat TV dinners have the same "Keep frozen. Cook Thoroughly" warning on the package.

Can somebody tell me what the actual risk of getting sick from one bite of cold fish would be? Or possibly help me determine if it was pre-cooked or raw? I know this is dumb but I don't want to worry all day. Thanks in advance.
