I purchased vacuum-packed Flounder and the individual wrapped filets bear the following statement:
Must remove from packaging before thawing. Do not refreeze.
Now, "do not refreeze" is straightforward. We were taught in grade school, don't re-freeze meat or food poisoning can result.
Does "must remove from packaging before thawing" have a similarly health-oriented cause? Or is it simply less damaging to the filet to remove it from vacuum-packing while it's frozen? This advice is contrary to the simplicity and neatness of thawing the fish while it's still vacuum-packed.
My question is, is there a health-related reason not to thaw it while still in the vacuum-pack?
