One of the most confusing parts of a kitchen has nothing to do with cooking. It's the little date printed on the carton.
If you have ever stood in front of the fridge holding a jar of pasta sauce and squinting at a stamp that says “Best by Sept 12,” you already know why this topic matters. It can help older adults eat well without wasting money.
What Those Labels Actually Mean
Most food dates in the United States are not federal safety deadlines. They are quality guesses from the manufacturer.
The USDA Food Safety and Inspection Service explains that, except for infant formula, federal law does not require date labels. These labels also do not necessarily mean that food is unsafe to eat.
You will see a few common phrases. "Best if used by" refers to peak flavor and texture. "Sell by" is a message to the store, not to you. "Use by" is the manufacturer's estimate of the last day of top quality. A yogurt three days past its "best by" date is almost always fine. Raw chicken a week past its "sell by" date is not.
Foods Where the Date Really Does Matter
Some products deserve more caution. Infant formula is the one federally regulated product. Deli salads, soft cheeses, cut melon, sprouts, raw seafood, and pre-cooked meats such as hot dogs and lunch meat can carry Listeria. The bacteria can grow even when these foods are stored in a cold refrigerator.
If you are over 65, your immune response is not what it was at 30, and listeria hits older adults harder. For these items, follow the printed date and keep the fridge at 40 degrees Fahrenheit or below. Toss them if you are unsure. When in doubt, throw it out.
Your Senses Are Better Than the Label
The MedlinePlus food safety guide and consumer educators agree: your nose, eyes, and hands are excellent judges of most everyday foods.
Sour milk smells sour. Slimy chicken feels wrong. Bread with a fuzzy green spot has told you everything you need to know.
A few honest checks. Milk past its date: sniff first, then taste a small sip; if it is sharp, pour it out. Eggs: Float one in cool water. Sinks flat, it is fresh; stands up, use it soon; floats, discard.
Canned goods with a dented seam or bulging lid should go straight to the trash. Leftovers keep for three to four days in the fridge, dated or not.
Small Habits That Save Food and Money
Groceries cost more than they used to. A few small habits help. Label leftovers with the date you cooked them using masking tape and a marker. Keep the fridge at 37 degrees. Put newer items behind older ones.
Freeze bread and half-loaves of anything you cannot finish in a week. Cooking for one or two is its own puzzle. Buy the smaller pack even when the per-ounce price is higher. Less waste beats a bargain that ends in the bin.
