E Minamata disease Q&A

2. Medicine

Q2: Why were some babies born having Minamata disease?

A2: Because methylmercury accumulates in fetus.

Commentary:
Minamata disease is caused by methylmercury that accumulates in organs.
In some cases, babies developed Minamata disease because methylmercury can be transported via the placenta from their pregnant mother.
This is called fetal Minamata disease.
There was a case that a child who ate a lot of methylmercury-contaminated fish developed Minamata disease (acquired infantile Minamata disease).
