Netflix has (so far) six episodes of a documentary about our food supply. This stuff fascinates me but for those who prefer the tl;dw (spoiler alert) I'll summarize:
Americans have come to believe honey is a healthy sweetener, so demand is booming. Trouble is, the bees aren't doing well, so production is decreasing. No one knows how to solve the bee problem, so China started mixing rice syrup into the honey to meet demand.
They dumped huge quantities of cheap rice syrup honey in the US, putting US producers out of business, so the US slapped tariffs on Chinese honey. And suddenly rice syrup honey started coming in the same quantities from Malaysia, Vietnam, etc.
So the government set up test labs, which created an arms race between the honey adulterators, as they're called, and the test labs.
Meanwhile, the price pressure on US producers got so high they started shipping their bees to the California almond orchards for a few months each spring to use the bees as pollinators and supplement their income. Which became like daycare for bees, germs spreading from colony to colony, so some producers started using antibiotics for the bees, which gets in the honey, and some of the antibiotics are not safe for humans.
Moral of the depressing story: buy local honey from beekeepers in your area. Honey laundering.
