Another reason to avoid galvanized in general is because it can potentially be toxic especially when it is in places where there are things for the coating to react with (eg. human body). The coating usually takes on a dull gray appearance.

A good rule of thumb would be to look for things that are food grade such as stainless.

I'm rather anal about things that are exposed to the human body, especially some metals. In one of the toys I have been working on I went so far to grab up some brazing rod that is used in the brewing industry to try and get something as safe as possible.
