How Long Is Food Good for After Expiration Date?

Most food is safe to eat past its date label, but how long depends on the type and storage. Shelf-stable items like canned goods can last years.

Standing in your kitchen, you spot a can of soup with a date from two years ago. The milk in the fridge has a “sell by” stamp from last week. You probably wonder whether to toss everything or eat it anyway.

The answer isn’t a simple yes or no. Most date labels aren’t about safety — they’re about peak quality. With proper storage, many foods stay edible far longer than the printed date suggests. The timeline varies by food type, but understanding the labels makes the decision clearer.

What Those Date Labels Actually Mean

“Sell By,” “Best if Used By,” and “Use-By” all sound like safety deadlines, but they’re not. The USDA explains that “Sell By” tells retailers how long to display the product — it’s not a safety date. Food is still safe to eat after that date if stored properly.

“Best if Used By” refers to flavor and texture, not safety. “Use-By” is the last date for peak quality, and the only exception is infant formula, where it goes beyond quality. For everything else, these dates are quality indicators.

Knowing this saves money and reduces waste. A university extension expert from Georgia notes that properly stored milk can remain safe past its date, and canned goods buried in the back of a pantry may still be fine.

Why The Confusion Sticks

Food companies print these dates in different ways with no federal standard (except for infant formula). Shoppers assume a date equals an expiration, and manufacturers have no reason to correct that — it drives more sales.

The result is an estimated 30-40% of the U.S. food supply gets wasted each year. A lot of that waste comes from generally considered safe food being tossed because of a misunderstood date. Once you know the labels are about quality, the whole picture changes.

Think about canned goods: the “best by” date on a can typically refers to quality. While flavor and aroma can deteriorate over 10 or 20 years, the food can still be eaten.

How Long Different Foods Last Past Their Date

The timeline varies widely by food category. Canned goods are the most forgiving, while dairy and fresh items need closer attention. Here’s a breakdown with specific shelf lives from USDA and university guidelines.

• High-acid canned foods (tomatoes, fruits, sauerkraut): Keep best quality for 12 to 18 months on the shelf. After that, safety is still good but taste and texture may decline.
• Low-acid canned foods (meats, stews, corn, carrots): Safe for 2 to 5 years past the code date. The lower acidity prevents bacterial growth longer.
• Dry mixes (hamburger helper, dry soup): Can be used for up to 2 years past the marked date if stored in a cool, dry place.
• Unopened milk: Generally good for up to 7 days past the expiration date, according to EatingWell’s review of dairy safety. Opened milk is best within 3 days past the date.
• Shelf-stable canned goods (general): The USDA says they are safe more or less indefinitely — up to five years or more. Even dents are not automatic death sentences unless rusted or bulging.

A food safety expert from the University of Georgia walks through these distinctions in their explainer on date labels. The key is that each food type has its own timeline, but none automatically becomes dangerous the moment the clock hits midnight.

Signs It’s Time To Toss, Not Trust

Your senses are better than any date stamp. The food safety after date notes that food is generally safe if consumed past its “use-by” or “sell-by” date, but may have declined in flavor, texture, or appearance. Spoilage organisms cause smells, molds, and sliminess long before pathogens become a problem.

Here are the clear red flags:

1. Smell test: Anything that smells sour, rancid, or off — especially dairy, meat, and seafood — gets tossed immediately.
2. Mold: Visible mold on soft foods like bread, cheese, or leftovers means discard. On hard cheeses, you can cut 1 inch around and below the mold spot.
3. Texture changes: Slimy meat, mushy vegetables, or separated liquids in canned goods (if accompanied by a bad smell) are warning signs.
4. Bulging cans or jars: A bulging lid or hissing sound when opened indicates gas from bacterial growth — don’t taste it.

When in doubt, err on the side of caution. But for many foods, a past date with normal smell, appearance, and texture means it’s still safe.

Smart Storage Extends That Window

How you store food matters as much as the date. Canned goods kept in a cool, dark pantry last years longer than those exposed to heat or sunlight. Dry mixes need airtight containers to keep out moisture and pests.

Refrigerated items stay safe longer when your fridge is at or below 40°F. A fridge thermometer costs a few dollars and prevents guessing. Freezers at 0°F stop bacterial growth entirely — frozen foods are safe indefinitely, though quality fades over months.

High-acid canned foods such as tomatoes and fruits keep best within 18 months of the code date. Low-acid canned goods like meat and vegetables have a shelf life of 2 to 5 years after that date. Following these timelines from the USDA helps you plan your pantry rotation without waste.

Trust your senses and these storage rules, and you’ll toss far less food. A past date on a can doesn’t mean it’s time for the trash — it means check the condition first.

The Bottom Line

Date labels on most foods are about quality, not safety. Canned goods can last years past the date, dry mixes up to two years, and milk a few days to a week. The smell, look, and feel of food are better guides than the stamp on the package.
