Food waste is a major issue all around the world, but one Swedish company is doing something about it. Coop has officially launched an ‘Old Milk’ fragrance — which, yes, smells like spoiled milk — to urge citizens to rely on their sense of taste and smell rather than expiration dates when deciding whether to throw away outdated food.

A study by the Swedish Environmental Protection Agency shows that 30 percent of food waste in Sweden is still edible. It is estimated that most food waste in the world is from dairy products, tea and coffee. To combat wasting this amount of food, Coop, a popular grocery chain in the country, developed a spray that smells like spoiled milk. The hope is that the fragrance will encourage people to smell and taste food before tossing it out.
