According to the Dairy Council of California, the shelf life of milk is affected by several factors, including how it is handled before and after it is purchased. When stored at 40 degrees Fahrenheit and not left out of the refrigerator for extended time periods, milk should last approximately five to seven days past the "sell by" date."

The type of cheese contributes to its shelf life. Soft cheese (cream cheese) will last up to two weeks, whereas a medium or hard cheese (cheddar) can last three to six months.

The Egg Safety Center reports that the dates on egg cartons are not food expiration dates, but guidelines. Raw eggs can stay good for approximately three to five weeks after the date of purchase as long as they are not cracked or damaged.

Baked Goods and Snack Foods

Baked goods and snacks typically have a Use-By Date.

Store-bought bread will typically last five to seven days at room temperature, but can last one to two weeks in the refrigerator. Fresh-baked bread do not contain preservatives, so they typically won't keep as long as commercially packaged breads.
