Piercings subject an individual to health risks, including excessive bleeding, nerve damage, keloid tissue development and skin infections, according to the California State University at Long Beach Health Resource Center. Equipment contaminated by blood that contains pathogens for tetanus, HIV, or hepatitis B and C potentially transmits those diseases.
The Association for Professional Piercers sets cleanliness standards, monitors federal regulation compliance and licenses piercing studios, explains the California State University at Long Beach Health Resource Center. Compliant piercing salons have current Association for Professional Piercers licenses as well as public health department permits when necessary. It is a good idea to observe the piercer at work and ask questions about his practices regarding glove use, sterilizing equipment and disinfection of work areas between clients.
