Many people assume that any date printed on food packaging marks the exact moment a product becomes unsafe to eat. But the truth is that date labels are often more about quality control and retail management than they are about safety. While some foods truly do become dangerous after a certain point, many items remain safe to eat well past the date printed on the package.

What Do Date Labels Actually Mean?

Most date labels are designed to help stores manage inventory or indicate peak freshness—not to warn consumers that a product is immediately unsafe. Here’s what the most common labels actually mean:

• Sell-by date: This tells retailers how long to display the product on shelves. It’s not a safety deadline for consumers.

• Use-by date: This usually refers to the product’s best quality—taste, texture, and freshness.

• Best if used by: Similar to “use-by,” this label indicates the manufacturer’s estimate of peak flavor, not safety.

• Closed or coded dates: These are mainly used by manufacturers for tracking batches and production timing.

In fact, the FDA does not require expiration dates on most foods, with the major exception being infant formula. That means many products are technically still safe to consume even after the date has passed, as long as they’ve been stored correctly.

So Why Do Expiration Dates Matter at All?

Even though most date labels aren’t strict safety indicators, they still matter—especially for foods that spoil quickly or are prone to bacterial growth. The problem is that harmful bacteria don’t always cause obvious signs of spoilage. Food can look and smell fine, but still be contaminated with dangerous bacteria that can cause foodborne illness.

This is why certain perishable foods should be treated with extra caution. When eaten after their recommended date, these items can significantly increase your risk of getting sick—even if they appear normal.

High-Risk Foods You Should Never Ignore

Some foods spoil faster and carry a higher risk of bacterial contamination. Here are two of the most common examples:

1. Egg Substitutes

Liquid egg products, like egg whites or egg substitutes, spoil faster than whole eggs. They often contain added ingredients and are more vulnerable to bacterial growth once opened. Even if the carton looks fine, using egg substitutes beyond their date or a few days after opening can put you at risk. These products should be consumed quickly, and any unusual odor or texture should be treated as a warning sign.

2. Soft Cheeses

Soft cheeses are among the most sensitive dairy products because they contain more moisture and have a higher risk of mold and bacterial growth. These include:

• Ricotta

• Cream cheese

• Feta

• Goat cheese

Soft cheeses should be discarded once past their date, or after about a week of opening—whichever comes first. Even if they look okay, the risk of bacteria like Listeria can increase rapidly in these products, especially when stored improperly.

How to Stay Safe While Avoiding Waste

The best way to protect yourself is to combine date labels with common sense:

• Store food properly: Keep dairy and eggs refrigerated at the correct temperature.

• Check for visible signs: Mold, slime, discoloration, or unusual odors are red flags.

• When in doubt, throw it out: If you’re unsure, don’t risk it—foodborne illness is not worth saving a few dollars.

The Bottom Line

While many date labels are meant to indicate quality rather than safety, they still matter—especially for foods that spoil quickly or are vulnerable to bacterial contamination. Being aware of which products require extra caution can help you protect your health and keep your family safe.
