Expiration date only!! http://www.recipe4living.com/Common/Article.aspx?id=50926 There is a chart that shows how long it is safe to store all food items. You have to be careful with anything that has yeast. It has bad effects after the use by date. Make sure ALL cake mixes and pancake mixes are not used past the due date. The yeast in them can make you extremely ill.
