Freezing keeps food safe to eat indefinitely, but these 39 foods significantly decrease in quality if they reach subzero temperatures.
Here's how long meat is good for in the fridge: Raw ground meats, all poultry, seafood, and variety meats: one to two days; raw roasts, steaks, and chops (beef, veal, lamb, and pork): three to ...
Food storage in refrigerators may not be safe unless there is close adherence to temperature guidelines. In general the temperature should be maintained at 4 °C (39 °F) or below but never below 1 °C (34 °F). [8] Safe storage times vary from food to food and may depend on how the food has been treated prior to being placed in the refrigerator.
Label storage containers with the cooking date so you know how long they'll stay fresh. Most cooked dishes last 3 to 4 days in the fridge and up to three months in the freezer. Storing and ...

[ 27 ] For example, liquid foods like soup kept in a hot slow cooker (149°F or 65°C) may last only a few hours before contamination [ citation needed ] , but fresh meats like beef and lamb that are promptly frozen (-2°C) can last up to a year.
It is also possible to freeze food by immersion in the warmer (at −70 °C (−94 °F)), but cheaper, liquid carbon dioxide, which can be produced by mechanical freezing (see below). [8] Most frozen food is instead frozen using a mechanical process using the vapor-compression refrigeration technology similar to ordinary freezers. Such a ...
