When Do Foods Spoil?
If you’ve ever sniffed an open carton of milk wondering if it’s still good to drink, or tried to decide if those leftovers were still safe to eat, you probably find that you throw out food more often than you’d like. Stale bread, overripe fruit and moldy cheese are not only unpleasant and potential health hazards, but wasted food is one of the biggest blows to your food budget.
By handling and storing food properly, knowing how long various food items stay good to eat, and consuming edibles before they spoil, you reduce food expenses, avoid the risk of stomach trouble and cut down on waste.
When Do Fresh Fruits and Vegetables Spoil?
It’s a shame to toss out produce because it has turned overripe, squishy or moldy. Only buy as much fresh fruits and vegetables as your family will consume within a week, and use the following guidelines for storage.

- Berries: two to four days in the fridge
- Citrus fruit: room temperature up to a week, around two weeks if refrigerated

When Do Meat and Fish Go Bad?
Fresh meat is highly perishable. Keep it in the refrigerator until you are ready to cook it, and don’t leave meat out on the countertop to thaw.
- Solid cuts of beef, lamb and pork can be stored in the fridge for up to five days before cooking. Once cooked, they are safe for up to three days if refrigerated.
- Poultry, fish, shellfish and ground meats should be cooked within two days of refrigerating. Once cooked, they are safe in the fridge for up to four additional days.
- Keep eggs in the refrigerator, where they will last for up to a month past the “sell by” date.
How Long Do Dairy Products Last?
Always check “sell by” dates when purchasing dairy items and store in the refrigerator as soon as you get home. Once opened, you can follow these general guidelines:

- Cream: ten days
- Sour cream: up to three weeks
- Yogurt: seven to ten days

How Long Do Baked Goods Stay Fresh?

- Tomatoes, pineapple or highly acidic foods: one year
- Other fruits, vegetables or meats: up to five years

Start Off With The Freshest Food Possible
The fresher your food is to start with, the longer it will stay good once inside your home.
- Always buy from sources with high turnover and clean facilities.
- Check purchase-by dates on all perishable foods before buying. Check the items toward the back of the shelf, as grocery store employees usually try to rotate stock, with the older items moving toward the front.
- When buying bread or other foods in plastic bags, make sure there are no small rips or tears in the package.
- Avoid produce that is limp, dry, discolored or has bruises or insect damage.
- Don’t take cans with dents or bulges.
- Boxed products should have no holes, gaps or tears in the packaging.
- Fresh meat should not have an iridescent shine, strong smell or darkened color.
The National Resources Defense Council estimates that the average American family loses $2,275 each year in wasted food. Cut down on money lost to spoiled food by storing it properly, and eating it within the recommended guidelines. Your taste buds and your wallet will both thank you.
