Shelf-life: Best before and Use by Dates

New technologies to predict spoilage time could slash the massive waste between farm and fork. In August , a can of Great Value peas joined the nonperishables in my pantry, one of several panic purchases as Hurricane Irene barreled toward my home on the northeast US coast. But the emergency passed, and the can, with its unassuming blue-on-white outline font, remains on my shelf seven years later. Can canned peas go bad? How would I know if they had? Such confusion, common in many a cupboard, drives an enormous amount of food waste: About 40 percent of food in the US gets trashed, often due to belief that a gone-by date on a package means the food is not safe. Many countries have simplified food packaging to carry a use-by date for when a product might actually go bad or a best-before date reflecting when it might start to become less palatable. US manufacturing groups recently announced voluntary guidelines to adopt such nomenclature. But this may not help much to reduce food waste. A better solution — and more effective waste reduction — could come from a flurry of progress in the science of determining and tracking shelf life , say Ross and other experts.

Back to Eat well. Food labels can help us choose a healthier diet and make sure our foods are safe to eat. Here’s a guide to some of the most common food labelling terms. But understanding all of that information is important if we’re to make use of it. For example, if a food product is labelled “light” or “lite” or has “no added sugar”, what does this mean?
