The U.S. Food and Drug Administration (FDA) has uncovered bacterial contamination in nearly half of permanent makeup (PMU) ink samples and about a quarter of tattoo ink products. Alarmingly, these samples included products from popular brands that claim to be “sterile.”
Extensive testing reveals widespread contamination
FDA scientists tested 75 tattoo and PMU inks for the presence of aerobic and anaerobic bacteria. The findings, published in the journal Applied and Environmental Microbiology on Tuesday (July 2), highlight the significant contamination issues within the industry.
Increasing risk with growing popularity
As the popularity of tattoos and PMU inks grows, the FDA has raised concerns about the contamination in these products, which have previously led to outbreaks of infections. Last year, the FDA issued guidelines for tattoo ink manufacturers and distributors, urging them to take precautions to prevent microbial contamination.
Startling statistics from the study
Researchers examined 49 tattoo ink samples, discovering bacterial growth in nine of them. Among the PMU inks, 17 out of 35 samples were found to be contaminated. Notably, 35 percent of the sealed and unopened inks tested contained both aerobic and anaerobic bacteria.
Aerobic bacteria thrive in the presence of oxygen, while anaerobic bacteria can survive without it. Both types of bacteria can reside in the dermal skin layer and in injured human tissue, posing serious health risks.
The study did not specify which brands were included or whether the FDA took any measures against the brands whose products were found to be contaminated. Researchers suggest that the sterilization processes claimed by these brands are either ineffective or falsely advertised.
Shifting perspectives on tattoo-related infections
Previously, it was believed that tattoo-related infections and complications were primarily due to allergic and inflammatory reactions caused by improper hygiene. However, recent studies, including this latest FDA research, indicate that ink contamination may also be a significant factor.
