We’ve all been there—standing in front of the fridge, debating whether that yogurt, deli meat, or bottle of salad dressing is still safe to eat. While some food expiration dates are flexible, others should never be ignored.
Consuming expired food can lead to foodborne illnesses, including serious bacterial infections. To keep your meals safe and your stomach happy, here are 10 food expiration dates you should always take seriously.
1. Deli Meats
WANT TO SAVE THIS RECIPE?
Pre-packaged and freshly sliced deli meats have a surprisingly short shelf life, even when stored properly. Once opened, they should be consumed within 3 to 5 days to avoid bacterial growth, particularly listeria, which can thrive in cold environments.
Even if they look and smell fine, eating expired deli meats is risky. If you notice any sliminess, an off smell, or discoloration, it’s time to toss them out immediately.

2. Soft Cheeses

While hard cheeses like cheddar or parmesan can often be salvaged by cutting off moldy sections, soft cheeses like brie, ricotta, and goat cheese should never be eaten past their expiration date.
The high moisture content makes them a breeding ground for harmful bacteria such as listeria and salmonella. If your soft cheese smells sour, has an unusual texture, or shows any signs of mold, don’t take the risk—throw it out.

3. Raw Meat and Poultry
Raw meat and poultry have strict expiration timelines that should never be ignored. Even when stored in the fridge, ground meats should be used within 1 to 2 days, while whole cuts of beef, pork, or chicken last about 3 to 5 days.
After their expiration date, they can harbor dangerous bacteria like E. coli and salmonella. When in doubt, check for a sour smell, slimy texture, or color changes.

4. Fresh Seafood
Seafood is one of the most perishable foods in your kitchen, and eating expired fish or shellfish can result in serious food poisoning.
Fresh fish should be consumed within 1 to 2 days of purchase, while shellfish like shrimp, scallops, and mussels should be eaten immediately after their expiration date. If your seafood smells overly fishy or ammonia-like, feels slimy, or has a dull color, it’s time to say goodbye.

5. Dairy Milk and Cream
Unlike some foods that are fine a few days past their expiration date, milk and cream should be taken seriously. Expired dairy can develop harmful bacteria that cause foodborne illnesses.
While sour milk might not always be dangerous, it’s best to avoid drinking it once it develops an off smell, curdled texture, or strange taste. If you’re unsure, pour a small amount into a glass and check for any changes.

6. Eggs
Eggs might seem like they last forever, but their expiration date matters. Consuming bad eggs can expose you to salmonella, which can cause severe food poisoning.
While some eggs are still safe a few days past their expiration date, always perform a float test—fresh eggs sink in water, while expired ones float. If you notice a foul odor when cracking an egg, discard it immediately to avoid contamination.

7. Fresh Berries
Berries may look harmless when they start to soften, but they can develop mold and bacteria quickly. Because they have high moisture content, mold spores spread rapidly, often contaminating surrounding berries even if they look fine.
Eating moldy berries can cause digestive issues and allergic reactions. To prolong their shelf life, store them in a breathable container, wash them just before eating, and discard any that show signs of spoilage.

8. Bagged Salads and Pre-Cut Produce
Bagged salads and pre-cut fruits or vegetables are convenient, but they spoil faster than whole produce. Once they pass their expiration date, they become a breeding ground for bacteria like E. coli and listeria.
Even if the greens or fruit look fine, consuming them past their prime can be risky. If your salad mix is slimy, discolored, or has an off-putting smell, it’s best to throw it away immediately.

9. Fresh Juice
Unlike store-bought, shelf-stable juices, fresh juices have a very short lifespan due to the lack of preservatives. Once opened, they should be consumed within 3 to 5 days.
Drinking expired fresh juice can expose you to harmful bacteria, leading to stomach issues and food poisoning. If your juice has a fermented smell, strange bubbles, or an overly sour taste, it’s gone bad and should be tossed.

10. Infant Formula
Unlike other packaged foods, infant formula has a strict expiration date that should never be ignored. The nutrients in formula break down over time, and expired formula may not provide the necessary nutrition for infants.
Additionally, bacteria can develop in old formula, posing serious health risks to babies. Always check the expiration date before feeding, and discard any formula that has passed its labeled shelf life.
