French beekeepers were recently shocked when their bees started producing thick, blue and green honey.

After investigating, they discovered their bees were feeding on the colourful shells of M&Ms – a Mars processing plant was located just 4 km away.

The Mars waste-processing plant has now solved the problem and are cleaning any outdoor or uncovered containers that M&M waste was stored in, so it’s unlikely you’ll see the blue honey on the market any time soon.
