We all glance at those “sell by,” “use by,” or “best before” dates—and often keep eating anyway—until trouble strikes. But certain foods cross a line where the expiration date becomes about more than just quality—it’s about safety. Eating past that line can expose you to dangerous bacteria, toxins, or nutrient loss you can’t see or smell. Knowing which foods to never push beyond their expiration dates is key to keeping your kitchen safe. Here are the nine foods that are not worth the risk.
1. Infant Formula
Infant formula is a rare product for which the expiration date is legally binding. After that date, the nutrient levels, especially vitamins, may degrade—so the formula no longer meets label claims. The FDA and food safety experts all agree: formula past its expiration date should be discarded, no exceptions. Since babies depend entirely on formula for nutrition, the risk is unacceptable. This is arguably the clearest case where the expiration date always matters.
2. Fresh Meat and Poultry
Raw meats and poultry are breeding grounds for dangerous bacteria as they age. Even if stored cold, strains like Salmonella, Listeria, and E. coli multiply—sometimes without obvious odor or visual cues. Once the expiration date passes, the margin for error shrinks fast. Cooking can kill bacteria, but toxins some bacteria produce may persist. Best practice: never consume raw meat or chicken past its labeled date, and freeze it well before then if needed.
3. Seafood and Shellfish
Fish and shellfish spoil rapidly, even when properly refrigerated. The texture, smell, and color change fast—sometimes before it’s obvious to the eye or nose. Past the expiration date, the risk of histamine poisoning, bacterial overgrowth, or spoilage rises sharply. Cooking spoiled fish doesn’t always make it safe. Always discard seafood once it’s past its use-by or expiration date, regardless of how “fresh” it looks.
4. Soft Cheeses (Ricotta, Brie, Cottage, Cream Cheese)
Soft cheeses are moist and have a texture that encourages mold and bacteria infiltration. Unlike hard cheeses, you can’t reliably trim off mold and salvage the rest. Once the expiration date passes (or mold is visible), they become hazardous. Pathogens like Listeria can spread invisibly through the whole batch. In short: soft cheeses past expiration aren’t just “off”—they can be dangerous.
5. Deli Meats and Cold Cuts
Processed meats like lunchmeats and cold cuts may contain preservatives, but they still spoil quickly. After the expiration date, moisture and low salt make them susceptible to bacterial growth. Listeria in particular is a concern, and it can grow at refrigerator temperatures. Smell and texture changes can be subtle, making them dangerous. It’s safest to toss all deli meats once they pass the dated label.
6. Pasteurized Milk & Cream Products
Dairy products like milk, half-and-half, whipping cream, and cream-based items have a limited window. After the expiration date, bacterial growth accelerates, and spoilage, sour smell, and curdling become likely. Pathogens such as E. coli or Salmonella can lurk. Even if the milk looks okay, it’s a gamble. Always discard dairy once its expiration date is passed, not just when it smells off.
7. Egg Substitutes & Liquid Eggs
Egg substitutes or liquid egg products in cartons are more fragile than whole eggs. They’re often pasteurized but have added water, which increases spoilage risk. Once the expiration date passes, bacteria multiply more readily. The risk is higher than with whole eggs. Even if unopened, these products should not be consumed past their date.
8. Pre-Packaged Salads & Cut Produce
Once fruits or vegetables are cut, sealed, or packaged, they lose their protective skin and ideal conditions. After the expiration date, bacterial and mold growth accelerate, especially in moist environments. Even rigorous rinsing won’t remove invisible pathogens. Eating expired pre-cut salad or fruit is a known culprit in foodborne illness. Discard all packaged produce past the printed date, no second chances.
9. Yogurt (Especially Non-Greek or Flavored)
Yogurt (non-Greek varieties, especially with added fruit or flavorings) contains live cultures but also moisture and sugars—ideal for spoilage. Past the expiration date, molds or harmful bacteria may overrun the beneficial ones. Sometimes the odor or appearance changes, but other times, spoilage is subtle. Because yogurt is soft and moist, pathogens can spread throughout. It’s not wise to risk it: toss yogurt past its date.
Why the Rest of the Pantry Is Safer (with Sense)
Expiration dates on many shelf-stable items—canned goods, dried pasta, cereals—are usually about quality, not safety. The USDA states that most date labels (except for formula) are manufacturer guidelines about peak flavor. As long as packaging is intact and there are no signs of spoilage, these foods often remain safe past their “best by” mark. That said, don’t ignore bulging cans, damaged seals, mold, or off smells. Use your senses first—then the date as a backup.
Certain foods demand strict adherence to the expiration date because you can’t “see” the danger before it’s too late. Infant formula, raw meats, soft cheeses, deli meats, dairy, seafood, egg substitutes, and cut produce fall into that high-risk zone. For these, quality loss and health hazard blur together. While many pantry staples offer more leeway, these nine items do not. Always respect their deadlines—no exceptions.
