There are three posible dates on the package but it's gotta be there somewhere if it's a packaged as opposed to a locally purchase or hunted turkey.
A "Sell by" date tells the store how long to display the product for sale. Consumers should buy the product before the date expires.
A "Best if Used By (or Before)" date is recommended for best flavor or quality. It is not a purchase or food safety date.
A "Use-By" date is the last date recommended for the use of the product while at peak quality. The date has been determined by the manufacturer of the product.
