[ventilize]

president's choice shirmp and penn and those kinds of meals i bought 4 of them and kept them in the tray of the freezer i had turned up my fridge a few weeks before hand and i am wondering if i will be getting sick because i cooked one up but there was ice on the bottom of the freezer so its keeping the packages colder then the fridge part wouldve so i should be alright i think ?

It's true to keep fridge at 40 and below I say keep it at 37-38 degree is preferred.
