(AP) – “Best before” labels are coming under scrutiny as concerns about food waste grow around the world. Manufacturers have used the labels for decades to estimate peak freshness. But “best before” labels have nothing to do with safety, and some worry they encourage consumers to throw away food that’s perfectly fine to eat. Major U.K. chains like Waitrose, Sainsbury’s and Marks & Spencer recently removed “best before” labels from prepackaged fruit and vegetables. The European Union is expected to announce a revamp to its labeling laws by the end of this year. In the U.S., there’s no similar push to scrap “best before” labels. But there is growing momentum to standardize the language on date labels to help educate buyers about food waste.
