13 Jun 2023 --- Following multiple reports of illnesses caused by microbially contaminated tattoo inks, the US FDA issued draft guidance to tattoo ink manufacturers and distributors to help recognize situations in which a tattoo ink may become contaminated with microorganisms, and thus, be potentially harmful to health. “Between 2003 and 2023, firms conducted 18 recalls of tattoo inks that were contaminated with a variety of microorganisms, some of which can cause serious infections,” outlines the government agency in a recent statement.
