Understanding the differences between Sell-By, Use-By, and Best-By dates is important for ensuring the safety and quality of the food you consume. These dates are provided by manufacturers to guide consumers and retailers on the best time to use or sell their products.

The Sell-By date is aimed at retailers, indicating the last date by which a product should be sold. It is not a safety date but rather a guideline for the retailer.

The Use-By date is the date recommended for the use of the product while it is at its peak quality. It is determined by the manufacturer and is based on factors such as the food's shelf life and potential for microbial growth.

The Best-By date signifies the date by which the product should be consumed to ensure the best flavor or quality. It is not a safety date but rather an indicator of optimal quality.

For example, if a carton of milk has a Sell-By date of October 15, it should be sold by that date but is still safe for consumption for a few days after. The Use-By date on a package of deli meat indicates the last day it is expected to be at its best quality, while the Best-By date on a box of cereal suggests the date by which it should be consumed for optimal taste.

It's important to note that these dates are not federally regulated except for infant formula, so understanding them can help consumers make informed decisions about the products they purchase and consume.
