A coloured honeycomb from a beehive is seen in Ribeauville, France. Bees at a cluster of bee hives in northeastern France have been producing honey in mysterious shades of blue and green, alarming their keepers who now believe residue from containers of M&M’s candy processed at a nearby biogas plant is the cause. Since August, beekeepers around the town of Ribeauville have seen bees returning to their hives carrying unidentified colorful substances that have turned their honey unnatural shades.
