11 Sep 2023 --- Sainsbury’s is replacing use-by dates with best-before dates across its own-brand milk range to reduce food waste. The new labeling will roll out in the new year, and the change will be complete by the end of February 2024. Research from UK-based charity The Waste and Resources Action Programme (WRAP) has shown that milk is the third most wasted food in the UK, with over 490 million pints thrown away each year, often because the milk has passed its use-by date. Sainsbury’s is the “biggest” UK retailer to make this change.
