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.
The manufacturer establishes the expiration date as being the last date they're willing to guarantee that the product will taste as intended. Past that you're taking your chances as far as taste goes, and if it's long past that, you may be taking chances as far as your health goes.
There really is no hard and fast rule for how long after the stated expiration date a product may remain tasty or safe. The best advice we can offer is: if it tastes (or smells) bad, don't eat it.
