Homemaker’s Column: Do You Know Just How Cold Your Freezer and Fridge Are?

Should you eat that slice of meat you just found in the back of the freezer? If you don’t know what it is and how long it’s been there, probably not. That’s just one of the kinds of questions on food safety that the Home and Garden Information Center at Clemson University gets regularly. Cold storage in the freezer or refrigerator is best to protect foods from bacterial growth — 40°F or lower in the refrigerator and 0°F or lower in the freezer. Nutrition in the fridge will freeze at 32°F, so ideal refrigerator temperatures are between 32 and 40°F. The only sure way to know your freezer and refrigerator settings for the proper temperatures is to buy two thermometers made in freezers or refrigerators and put them in your cold storage units.

Once you’ve done that, all you need to know is how different long foods will keep, keeping in mind the adage “If in doubt, throw it out!” Sometimes your nose will tell you all you need to know. When it comes to refrigerator storage, the following foods will keep no more than two days: fresh ground meats and stew meats; gravy and meat broth; fresh poultry and fresh fish; shrimp, scallops, crayfish, and squid; shucked clams, mussels, and oysters. The time limit extends to three to four days for fully cooked ham slices, meat and meat casseroles, chicken and chicken casseroles, pizza, and cooked fish and shellfish. Items to keep no more than three to five days in the fridge include opened packages of luncheon meats or deli meats; fully cooked ham portions; fresh meat steaks, chops, and roasts.

Fresh eggs in the shell will keep for three to five weeks, but hard-cooked eggs for no more than one week. Commercial mayonnaise will last for up to two months after being opened if kept in the refrigerator. Hard cheeses such as cheddar or Swiss will last three to four weeks in cold storage. For more than a week, don’t hold milk or soft cheeses such as brie or feta, cottage cheese, and ricotta. Yogurt can keep for up to two weeks. When storing foods in the freezer, use moisture-proof, freezer-weight wraps – such as bags and containers specifically intended for use in the freezer, heavy-duty foil, and freezer paper. Label and date all packages with a permanent marker and practice the “First in, first out!” rule.

Keep ice cream, sausage, ham, and hotdogs for no more than two months. For two to three months, you can keep the following: cooked leftover meat, gravy, and meat broth; fresh, fatty fish such as salmon, mackerel, and tuna. Three to four months is the limit for fresh giblets, raw ground meat or stew, and shucked shellfish. Four to six months is the limit for best quality cooked poultry or fresh lean fish such as cod, flounder, and trout. Use fresh frozen beef, poultry, venison, hard cheese, fruits, and vegetables within a year. Canned goods will not keep forever, either.

Use home-canned foods that have been processed by up-to-date, approved methods within a year. Commercially canned high-acid foods such as juices, tomatoes, fruits, pickles, and sauerkraut will store well for 12 to 18 months. Commercially canned low-acid foods such as meat and poultry products and vegetables will store well for two to five years. Storage won’t improve the quality of any food. Still, the rate will not decrease if the goods are correctly stored and the food eaten within the recommended time frame. For best quality, buy cans and jars free of dents, cracks, or bulging lids, which can indicate a severe food poisoning threat. Dusty cans or torn labels may indicate old stock.

When you bring home new canned goods, put them on the shelf behind the older cans and use the older goods first. Store canned foods in dry cabinets at a temperature between 50°F and 70°F. Avoid storage areas near hot pipes, an oven, a furnace, or direct sunlight. For more information on food safety, visit the Home and Garden Information Center webpage at
