Cindy you may have to pull the "ice block" of food out of the freezer. It's possible at that point that you could let it thaw enough to get the chunks of ice off of the food and then get it back into the freezer....
Hopefully someone else will have a better solution to the problem. Hope it works out so you don't lose any food!
