No risk, no worry: It isn't rust that causes tetanus. Tetanus bacteria often exist in dirty places (like soil and old nails) and usually can take hold only in deep wounds. The dirtin deep wounds is what leads some health education sources to mention rusty nails. But iron oxide (rust) in small amounts is harmless. (Your body is loaded with iron -- it give blood its red color!)
