Eli5, How does lead and other heavy metals keep winding up in our food and water?

267 views

I just read that Hershey is being sued because lead and cadmium were found in their dark chocolate. A few weeks ago, they found lead in baby food from just about every company except Gerber. Aren’t they supposed to test for that stuff?

Even the romans knew lead was bad for you when they used it in their plumbing, they just didn’t have anything else to use.

I worked at a assisted living facility and as part of my job, I was in charge of sending water samples to a test facility every month. I had to take samples weekly and date them, it was a pretty strict procedure.

I thought every company that sold food or water was required to test their products to meet FDA requirements, so how the hell does this still happen?

Some of the metals end up in food from coal fired powerplants. For example, mercury is often emitted from burning coal, which then ends up in local waterways and ultimately bioaccumulates in fish. The mercury can also end up in the soil and thus in food grown in nearby farms.
