These bees made blue honey after visiting an M&M factory

It’s no secret that bees are in trouble. Pesticides, habitat destruction, and climate change are driving a significant decline in their population. Despite efforts to ban harmful chemicals and introduce protection measures, the actions taken so far fall short of addressing the scale of the crisis.

Bee populations around the world continue to plummet, and the consequences are alarming—bees play a crucial role in pollinating the crops that sustain our food supply.

But there’s more to the problem than pesticides and habitat loss. Industrial expansion is encroaching on natural ecosystems, forcing bees to adapt to increasingly uninhabitable conditions. A startling example of this surfaced in Ribeauville, a small town in Alsace, France, where local beekeepers discovered their bees producing honey in unnatural hues of bright blue.

Normally, honey color ranges from light yellow to dark amber, influenced by the flowers the bees pollinate. But this bizarre phenomenon called for investigation.

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.

Beekeepers traced the cause back to a biogas facility processing waste from a nearby Mars factory, a producer of the colorful candy M&M’s. The sugary, dyed shells left in the plant’s poorly contained waste source became a food source for the bees, resulting in the oddly tinted honey.

Far from being an amusing anomaly, this polluted honey came with significant implications—it was unsellable due to unverified components, creating a financial burden for the local beekeeping community.

The situation highlights a deeper issue: how human industrial activity disrupts ecosystems and exacerbates the challenges bees already face. While the company operating the biogas plant claimed they were unaware of the problem, many argue that better containment and waste management practices could have prevented this entirely.

Such events underline the need for stricter regulations and genuine accountability from industries operating near natural habitats.

France, one of Europe’s largest honey producers, generates over 18,000 tonnes of honey annually, with Ribeauville responsible for about 1,000 tonnes. It remains unclear how much of this year’s production was affected by the tainted honey incident.

Yet the message is clear—without heightened awareness and committed action, the challenges facing bees will only grow.

Bees are the backbone of biodiversity and agriculture, pollinating an estimated 75% of the world’s leading food crops. Protecting them goes beyond offering temporary solutions.

It demands a united effort to regulate harmful practices, improve habitat preservation, and prevent industrial interference. If we want to secure a sustainable future—not just for bees, but for ourselves—it’s time to take the crisis seriously.
