Manufacturers print date labels on food packages to guide retailers and consumers in understanding the current condition of a specific food item.
However, some consumers continuously end up with spoiled food supply due to the ongoing confusion with these food labels. So what does best-by, sell-by, and use-by date mean?
Read on to learn the difference between best-by, sell-by, and use-by dates and everything about label dates to avoid food waste.
Defining Best-By, Sell-By, & Use-By Date
Best-by dates refer to the date printed on a food packaging that indicates when it should maintain its peak quality. It is not a purchase or safety date; this date tells when a food product should be consumed or used for the best quality.
Foods that are days past best-by dates are generally safe to eat, but the quality and texture may have declined.
Sell-by dates refer to the date printed on food packaging that indicates the date recommended by the manufacturer for retailers to sell the product.
It is not a purchase or safety date and is primarily intended for inventory management in grocery stores.
Foods that are days past sell-by dates are generally safe to eat, but the quality and flavor may have declined.
Use-by dates are no expiration dates and refer to the date printed on food packaging that indicates the last date by which perishable products should be used or consumed for food safety reasons.
Foods with past use-by dates are no longer safe to eat, and some health risks are associated.
How to Know When to Eat or Toss Food
Fresh produce should feel firm, have vibrant color, a fresh aroma, and no signs of wilting, damage, or bruising.
You’ll know if produce is spoiled or past its prime, if it feels soft or mushy, has a faded or dull color, has a bad smell, is wilted, and has cut.
Poultry products, including egg products, usually have a pack date and stamp of USDA grade shield, both of which you should look for. The meat should also have a pink or light beige color.

You must toss it if it gives off a rancid odor, slimy texture, mold, or discoloration in which the meat appears gray or greenish.
Check the printed date on dairy products which is usually sell-by and use-by dates. Also, you will determine they’re all right when they have a smooth and creamy texture.
If the product looks or smells sour or unusual or shows signs of spoilage, such as mold, discoloration, or an off-putting smell, it’s best to discard it.
Pasta & Grains
You will know if these products are still good to eat if the pasta is firm and the grains are uniform in color and shape.
If the product has signs of pests or insects, such as small holes in the packaging, or has a rancid odor, it’s best to toss it.
Canned & Boxed Foods
Most shelf-stable products like canned products and boxed foods usually have product dates from which you can refer in determining their freshness.
If there are any dents, rust, or swelling on canned foods and damages, bulges, or leaks on boxed foods, it’s time to toss them.
Difference Between Sell-By Date & Best-By Date
Sell-by date indicates when a product should be sold by the retailer, whereas the best-by date indicates when a product will stay fresh or have the best flavor or quality.
Nonetheless, both dates are intended to help consumers understand the food quality of a product, but in different ways.
Does the Law Require Food Product Dating?
No federal regulations require food dating for other products, though manufacturers may voluntarily choose to include a food label.
This date ensures that the formula is of its best quality and nutrition while promoting the safety and well-being of infants or babies.
How Do Manufacturers Determine the Quality Dates?
Manufacturers use various methods to determine the quality dates of food products, including accelerated shelf-life testing, real-time shelf-life testing, statistical analysis, packaging and storage studies, microbiological challenge studies, and field studies.
Manufacturers may also consult with food scientists, regulatory agencies, and industry standards organizations to ensure their quality dates align with the best practices and legal requirements.
Are Foods Safe to Eat After the Product Date Passes?
Generally, eating a food after its product date has passed may not be harmful as long as it shows no signs of spoilage, such as off odor, off-flavor, or visible mold growth.
However, if a product should develop unpleasant characteristics or show signs of food spoilage, it should be handled properly and discarded.
It depends on several factors, including the type of food, the storage conditions, and the specific product date in question.
What Do Can Codes Mean?
Can codes are a combination of letters and numbers stamped on canned goods to help manage inventory and track products intended for manufacturers.
These codes also identify the date the product was canned and when it should be consumed to avoid food waste.
However, the format varies and is not standardized among several manufacturers.
If there are no codes in your purchased canned goods, you can mark them with your purchase date instead to estimate their freshness, though canned products generally have a shelf life of at least two years.
Tips & Tricks to Extend Shelf Life of Foods
- Keep food items frozen to maintain peak quality, especially fresh beef, ground meat, fruits, and vegetables, stored in freezer-safe containers or bags.
- Avoid leaving foods at room temperature for more than two hours to reduce the risk of bacterial growth and prevent spoiled foods.
- Ensure foods like meats, dairy products, and produce are stored properly in the refrigerator. Store dry goods, such as grains and beans, in a cool, dry place.
What types of food are dated?
Food products (fresh meat, poultry, and dairy), packaged foods (canned, dry, and frozen goods), infant formula, and ready-to-eat foods (salads or sandwiches) can all be dated.
How long is food good after the sell-by date?
Many food items are generally safe to consume after the sell-by date has passed, especially if properly stored—even if it’s weeks past, as long as there are no visible spoilage bacteria.
Can you drink water after the best-by date?
Yes, water is generally safe to drink after its best-by date, as long as it was not exposed to contaminants and has been appropriately stored.
However, the plastic bottle from which the water comes has an expiration date, and drinking water from a bottle beyond its expiration date is not a good idea since the plastic can leach into the water over time .
Does best before mean expired?
No, the term best-before is not an expiration date but refers to the date until which the manufacturer expects it to retain its peak quality, flavor, and texture.
After the best-before date has passed, the product may not be at its optimal quality and is not often deemed as expired food. In most cases, it can still be safe to consume.
Food product dating is an essential tool that helps retailers and consumers identify the freshness and quality of food products they store or purchase.
However, product dates are not always a guarantee of safety but rather serve as a helpful guide only for retailers and consumers.
Therefore, it is crucial to properly store and handle food items in the right conditions to extend their shelf life and reduce the risk of foodborne illness.
