These labels are required as an “open date” regulation in Massachusetts for packaged food that has a shelf life of less than 90 days. However, there are no federal or state guidelines on expiration dates. While spoiled food is unpalatable, food safety experts say they aren’t particularly hazardous.
“Use-By” date and “Expires on” dates are the last date recommended for the use of the product while at peak quality, determined by the product manufacturer. These are not a purchase by or safety date.
“Sell-By” date tells the store how long to display the product for sale. You should purchase the product before the sell-by date.
“Best if Used By
[or Before]
” date is recommended for best flavor or quality. It is not a purchase or safety date.
You can trust and rely on your own sight and smell over food dates in most cases!
