Food Safety: How long can frozen vacuum-sealed steak wait in the refrigerator after thawing, before cooking? I'm not sure about the difference between community butcher packaging and cryovac. I've done this with steaks frozen for ~2mo at -18C and then left in the fridge at 5C for 12 days before cooking -- smelled fine, and tasted fine.
Deep freezers keep food colder than attached freezers. This extends the length of time you can freeze items safely. For that reason, as long as you keep the door(s) closed, a chest-style deep freezer will keep foods frozen for up to 72 hours without power.ood becomes unsafe when the temperature of the refrigerator goes above 45 degrees for more than two hours. In most small attached-style freezers, a half-full freezer will last up to 24 hours and a full freezer will last up to 48 hours.
