An outbreak of infected tattoos has led to an unlikely source: the ink. Now with the growing popularity of tattoos, health officials say they are seeing more cases of a nasty skin infection caused by a common bacteria traced to the ink. According to the a Rochester New York Newspaper, a 20-year-old man with a fresh tattoo and a stubborn rash sparked a months-long investigation by the Monroe County Department of Public Health traced the problem to premixed ink bought at a trade show in Arizona. The product in question, called “Catfish Carl’s Realistic Washes,” was voluntarily recalled in April by the maker, according to the FDA. Mycobacterium chelonae skin and soft tissue infections were isolated from a sealed batch of supposedly sterile premixed ink. Given the apparent popularity of tattoos, we advise people who have gotten a tattoo and who then develop a rash to not ignore it, but rather be evaluated by a physician because many of these infections can become serious and will not resolve without proper treatment. Such cases raise concerns that improper ink production could undermine patrons’ safety even when tattoo parlors adhere to best practices and standards. The outbreak is the first to be isolated to the ink manufacturing process, rather than unsafe hygienic practices at tattoo parlors, and points to a previously unrecognized risk. Permanent tattoos have become increasingly common in the United States, with 21% of adult Americans now sporting at least one, according to Centers for Disease Control and Prevention.” Currently there is no regulation requiring sterility of tattoo inks.
