The sell-by and best-by dates on milk cartons are ones we tend to pay close attention to. Many of us automatically discard milk if it is past one of those dates. However, those dates are not really scientifically established but rather are guesses based on experience.
We have talked about the problem of food waste before. About 40% of the food produced in the United States goes to waste, which is a truly shameful statistic. According to a Business for Social Responsibility study on the subject, about 44% of the food that goes into landfills comes from homes. About a third comes from the food service industry.
By some estimates, Americans waste as much as 40% of food that is produced. None of the reasons are anything to be proud of, but one of the most frustrating is the confusing array of food date labels that are supposed to tell us whether the food we purchased should be eaten.
