About 4 months ago I made some snack sticks, vacuum sealed and froze a few packs for storage. I go to thaw some out and notice these tiny white specks all over the snack sticks - in all of the packages. I've been thinking it is a mold of some sort however I wouldn't have thought mold would grow on vacuum sealed, frozen snack sticks. Anyone have any ideas as to what this is and if it's OK to eat? Thanks.
