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

263 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?

There are many ways that heavy metals like lead can end up in our food. For example, sometimes the soil that plants are grown in has lead in it, and when the plants absorb the water and nutrients they need to grow, they also take in the lead. Heavy metals can also get into the water that is used to grow or raise food, and then the food that is grown or raised in that water can end up having heavy metals in it. Finally, sometimes heavy metals can get into our food during the process of manufacturing or packaging, if the machines or containers that are used to make or store the food have been contaminated with heavy metals. It’s important to be aware of these potential sources of heavy metals in our food and to try to minimize our exposure to them, because heavy metals can be harmful to our health if we eat too much of them.
