Since last August, beekeepers near the town of Ribeauville in France, have been puzzled by their bees producing honey in mysterious shades of blue and green. Mystified, the beekeepers embarked on an investigation and discovered the odd honey colors can be traced back to a bio-gas plant that processes waste from an M&Ms factory.
“Bees are clever enough to know where the best sources of sugar are.” the spokeswoman for the British Beekeepers’ Association, Gill Maclean, told BBC. The company operating the bio-gas plant promised to clean its containers and store waste in airtight containers to prevent bees from reaching it. The green & blue honey will not be sold.
