No methanol poisoning nor changes in formaldehyde levels in the body.

没有甲醇中毒，体内甲醛含量也没有变化。

So nowadays, thankfully, methanol poisonings in the US are relatively rare.

所以现在，谢天谢地，甲醇中毒在美国相对罕见。

And that damage can be permanent, which is why methanol poisoning frequently causes blindness.

这种损害可能是永久性的，这就是甲醇中毒经常导致失明的原因。
