Does frozen food expire?

[richardhmc]

I have several different kinds of fish food - bloodworms, mysis shrimp, brine shrimp, human shrimp in the freezer. Is it okay to feed even after a long period of time?

For example, I have a packet of mysis shrimp that has been in the freezer for about 7 months. This is because I because I had two packs and it took me all this time to use that other pack. Also, I switch up what I feed. It should still be fine right?

I don't think those packets have an expiration date on them, but you would want to watch for freezer burn..where it starts to turn a different color than it should be. That might be a good time to chuck them & replace them.
Best not to keep them in the door compartments of the freezer so they have less chance of being exposed to warmer air that would cause them to deteriorate faster.
