I kind of hate expiration dates. People see food past the date and think the food is now tainted. Bacteria is what makes food go bad, and the bacteria has not been informed of the date upon which they are supposed to strike. So many factors go into when food will go bad and the best way to tell if food is bad is by smelling it and then tasting it. If it doesn't smell bad or taste bad it isn't bad, regardless of what date is on the package. Those dates are mostly for inventory control at the grocery store, and for that they are a good thing, but they have almost nothing to do with when food will go bad.
(TIME.com) -- Use-by dates are contributing to millions of pounds of wasted food each year.
A new report from the Natural Resources Defense Council and Harvard Law School's Food Law and Policy Clinic says Americans are prematurely throwing out food, largely because of confusion over what expiration dates actually mean. Most consumers mistakenly believe that expiration dates on food indicate how safe the food is to consume, when these dates actually aren't related to the risk of food poisoning or foodborne illness.
Food dating emerged in the 1970s, prompted by consumer demand as Americans produced less of their own food but still demanded information about how it was made. The dates solely indicate freshness, and are used by manufacturers to convey when the product is at its peak. That means the food does not expire in the sense of becoming inedible.
