beekeepers in Ribeauvillé, a town located in the Alsace region, have noticed that bees there have been making honey in many strange colors. Bees have been returning to apiaries (places where beehives are kept and honey is made) with different colors coating their bodies. The colors then end up contaminating the honey. 

A recent investigation revealed that a nearby M&M’s factory is behind the change in color. Waste from the factory has been exposing the bees to a number of chemicals. Some of the chemicals are used in the outer shells of the bite-size candies, which come in many bright colors. The local beekeepers do not know if the polluted honey is dangerous to eat, but they are not taking any chances. They are throwing away the candy-colored honey, which means a big loss to local businesses. “For me, it’s not honey,” Alain Frieh, leader of the town’s beekeepers union, tells the Reuters news agency. “It’s not sellable.”
