PRODUCT DATING INFORMATION - 2021
Every year in the U.S. 40 million tons (80 billion pounds) of food are wasted; about 219 pounds per person. That is more than $161 billion and 30-40% of the U.S. Food supply. By the end of April 2020, more than one in five households in the United States, and two in five households with mothers with children 12 and under, were food insecure. Please, don't throw away food unnecessarily. Learn what those dates on food packages mean.
The only foods that are required by federal law to have an expiration date are baby food and infant formula. DO NOT BUY OR USE BABY FORMULA OR BABY FOOD AFTER ITS “USE BY” DATE. However, some products designed for babies such as juice and cookies or biscuits can be distributed past their date and are safe to eat.
Many canned and boxed products are safe to eat long after the date on the container and the shelf life of refrigerated and frozen foods can be extended if they are handled properly. Once a perishable item is frozen, it doesn't matter if the date expires—foods kept frozen continuously are safe indefinitely, though the quality slowly deteriorates over time.
Some examples you will see on food items:
Expiration Date (such as expires 01/01/01 or Do Not Use After 01/01/01)
Look for it on baby food and formula, medications, vitamins, yeasts, baking powder
What it Means: Discard after the expiration dates. Yeast and baking powder work less well after the expiration date but are safe to eat.
Pack Date or Closed or Coded Dates (such as packed on 03/01/2012 or 22:5306412 or KL064)
Look for it on canned food crackers cookies spices
What it Means: Packing numbers for use by the manufacturer in tracking their products. This enables manufacturers to rotate their stock as well as locate their products in the event of a recall.
Sell-By Date (such as Sell By 01/1/01)
Look for it on refrigerated foods such as milk, yogurt cottage cheese, eggs, lunch meat, packaged salad mixes.
What it Means: Tells the store how long to display the product for sale. If the food has been handled properly, it is still safe to eat and the quality is good.
Shelf-stable product
Most shelf-stable or dry foods (cans, boxes, bags) remain edible for several days, months, or even years past their code ate. Always examine the packaging to make sure it has not bee damaged too much o that the food is no longer safe to eat.
Use-By or Quality Date (such as best if used by 01/01/01)
Look for it on crackers, cookies, cold cereals, and other dry, shelf-stable food.
What it Means: This date is the manufacture's recommendation for how long the food will be at peak quality. After the quality date, the food is still safe to eat but slowly begins to lose nutrients and the quality begins to lessen.
Best If Used By (or Before)
Recommended for best flavor or quality. It is NOT a purchase or safety date.
Frozen foods kept frozen without any thawing, will keep indefinitely.
