Did you know that "real" Parmesan cheese (Parmigiano-Reggiano) is made in copper vats?

And copper plumbing is super common for potable water?

And plenty of spirits are distilled in copper stills?

I mean, encouraging handwashing is fine but copper isn't what you need to worry about.

Maybe not. I don't know. I'm not a scientist. I have to err on the side of caution with these things because I don't know.

Copper is an essential trace element for many living organisms, including humans, meaning you need copper to survive. Generally, copper has low toxicity. (That is, unless you have rare genetic defects such as Wilson's Disease)

Lead is nothing like that. We don't need lead to survive, we shouldn't put lead in our bodies. Lead is also known to accumulate in your body (especially your brain). Avoid lead exposure as much as you can.
