Frozen food left out still good ?

  • We are currently upgrading MFK. thanks! -neo
As stated above, if they are the kind that are sealed in the individual blister packs, then you are absolutely fine, as they are not exposed to pen air, mold, bacteria, etc. Refreeze them and you will be just fine.
 
Don't take the chance. in my humble opinion..

There is no chance, if they are individually packed. Why is it so hard to understand that, if not exposed to bacteria, mold spores, or other contaminates, leaving this food to that for 20 hours WILL NT HARM YOUR FISH.

So many animals in the world eat dead animal tissue. It's a no brainer...
 
I say few hours ok, that long throw it away.
