Food expiration dates refer to quality, not safety, which means eggs, milk, and more are good to eat after the date on their packaging. Consider this your guide to when foods actually expire.

There's no standardized system for food dating in this country. So is it really any wonder why dates on packaged foods are a bit, um, baffling? Approximately 40 states require dates on some perishable foods, like meat and dairy, so nowadays you're likely to see your groceries labeled. But spoiler alert (pun intended): Food products are safe to consume past the date on the label, according to the USDA's Food Safety and Inspection Service (FSIS).

In order to reduce food waste, FSIS recommends that regardless of the date, consumers should evaluate the quality of the food before deciding to eat it or throw it away. (The one exception: Federal law requires a date on all infant formulas for safety and it should always be followed.) So what exactly do expiration dates mean then, and how long is food really good for?

With help from experts and product manufacturers, Real Simple compiled this simple guide to reading expiration dates and when to worry about food safety, so you can shop smarter and waste less.

How to Read Expiration Dates

Depending on where you live, you may see different dates on your food and each has a different purpose. Here's a bit of clarity based on information from the Institute of Food Technologists (IFT) and FSIS.

Best If Used By/Before: This is a quality assurance date, and serves as a "suggestion" for when the taste and quality of food is at its peak. It is not a purchase or safety date.

Use By: This is the suggested date by which you should eat the food. But just because it's a day or two past the use-by date doesn't mean that consuming it will make you sick, although you should evaluate the quality of the food yourself after this time. It is not a safety date, except when used on infant formula.

Sell By: If you're at the grocery store and the very last unit of your favorite yogurt has that day's sell-by date, you can still buy it. This is not a safety date, but rather a date for retailers that helps them determine how long an item should remain on the shelf. According to the IFT, "one-third of a food's shelf-life remains after the sell-by date for the consumer to use at home."

Freeze By: According to the USDA, this date indicates when a product should be frozen to maintain peak quality. It is not a purchase or safety date.

How Long Are Foods Good After the Expiration Date?

"With an exception of infant formula, if the date [on your food] passes during home storage, a product should still be safe and wholesome if handled properly until the time spoilage is evident," according FSIS. You can tell if a food is spoiled if it has an off odor, flavor, or texture.

With that in mind, here are the recommended expiration date guidelines for common foods thrown away too early.

How Long Does Canned Food Last?

Yes, canned food can go bad. According to the USDA, high-acid canned goods, like tomatoes and citrus fruits, will keep for up to 1.5 years. Low-acid canned goods-that's pretty much everything else, including vegetables, meat, and fish-will last for up to 5 years. Canned foods are sterile, so they won't host bacteria, but eventually the taste and texture of the items inside will deteriorate. Keep them at room temperature in a dark place, like a cabinet or a pantry, and avoid buying bulging, rusted, leaking, or deeply dented cans as they have higher chance of being spoiled.

How Long Does Frozen Food Last?

Items from the freezer section of the supermarket are safe to eat indefinitely. They have expiration dates because they won't taste good forever; flavor and texture break down over time. Once you open a bag of frozen peas or corn, pour out a portion rather than reaching in with your hand, which can introduce bacteria. (Bacteria can't grow in the freezer, but they can survive. If you don't cook an item after you defrost it, the bacteria could still be dangerous.)

How Long Do Leftovers Last?

Have a giant pot of chili that would feed a team of football players? Invite them over. According to the USDA, most refrigerated leftovers last 4 days, tops. Dishes that contain seafood or uncooked ingredients, like mayonnaise, spoil faster; eat them within a couple of days. And don't let uneaten food linger on the counter for more than 2 hours. The longer a dish sits at room temperature, the more susceptible it is to bacteria growth. It's fine to put warm food in the refrigerator or freezer. But when handling a dish that will take many hours to cool fully-a huge stockpot full of stew, say-transfer it to several smaller containers first.

Meanwhile, leftover meals you freeze yourself should be tossed in 3 to 4 months. After that, they can become icy and start to take on the flavors of other foods in the freezer.
