Beekeepers in Ribeauville, France were puzzled about why their bees were producing honey that came out green and blue ... until they found a biogas plant processing Mars candy waste some two-and-a-half miles away. "It appears the enterprising bees have been eating the waste from a nearby biogas plant that has been processing the waste produced in the making of M&Ms," reports The Independent's Rob Williams, while Reuters's Patrick Genthon says the keepers think it's specifically the "residue from containers of M&M's candy" that's making their honey turn funny colors. A similar thing happened stateside in 2010 according to The New York Times's Susan Dominus who reported that a woman's artisanal bees in Red Hook, Brooklyn, gorged themselves on maraschino cherry juice and turned their honey and honeycombs cough-syrup red. "We discovered the problem at the same time they did. We quickly put in place a procedure to stop it," said a co-manager of the plant, telling Genthon that the company will thoroughly clean its containers and waste would be stored in a covered hall.

Beekeepers tell Genthon that the blue-green honey still tastes like honey, but they won't be selling it. We don't blame them.  It's hard to imagine consumers smearing something that looks like paint onto their Greek yogurt. 

Nor do we think there's a market for Ecto Cooler Honey: 

And which batch of honey would you rather have in your tea?
