Blue honey traced to M and Ms

Beekeepers in northeastern France were puzzled to find their hives were full of honey in strange blue and green tints. Although flowers bloom in colors, the nectar from them is usually colorless. The culprit turned out to be candy-coated M&Ms! A biogas plant near Ribeauville in Alsace had contracted with a Mars candy manufacturer to process the plants waste products, which included the colored candy and food dye. The biogas company was red-faced when confronted with blue honey, and promised to rectify the situation by immediately covering the waste to prevent bees from eating it, and to process the materials as soon as possible. The blue and green honey will not be sold.
