Can decorative iron used for nail art cause tetanus?

Generally, whether decorative metal accessories used for nail art can cause tetanus depends on whether the skin is broken. Simply touching intact skin usually does not lead to infection; however, if the skin has an open wound and comes into contact with contaminated decorative metal, there may be a risk. The specific analysis is as follows:

If the skin on the hands is intact and the decorative nail accessories are only applied to the surface without causing scratches, punctures, or other injuries, bacteria from the accessory cannot enter the body, so tetanus will not occur, and there is no need for excessive concern.

However, if the decorative metal is rusty or contaminated with dirt and accidentally causes a scratch or puncture wound—especially when the wound is deep and narrow—tetanus-causing Clostridium tetani bacteria may multiply in such low-oxygen environments, increasing the risk of tetanus infection. This situation requires particular attention.

To reduce risks, check the condition of your skin before getting a manicure and treat any wounds beforehand. Choose clean, rust-free decorative accessories and clean tools promptly after use. If scratched, immediately wash the wound with soap and water and disinfect it to ensure basic protection.
