Stop Food Waste Day is observed worldwide on the last Wednesday of April. Launched in 2017 by Compass Group USA, this global day of action aims to address the issue of food loss and waste, which refers to food that is not consumed, whether during production, processing, distribution, or at the retail and consumption levels. It is estimated that about one third of all food produced for human consumption is lost or wasted. Participants are encouraged to prevent food waste by storing food properly, planning meals, and utilizing leftovers, while also inspiring others to do the same and repurposing food by donating excess to local charities. The event promotes various activities, including attending organized events, trying recipes that utilize leftover ingredients, and sharing experiences on social media with the hashtag #StopFoodWasteDay. Other related observances include World Disco Soup Day and the International Day of Awareness of Food Loss and Waste, which further emphasize the importance of reducing food waste.
