Tattoo ink poses a health risk: scientists have found 22 types of microbes in it
Anaerobic and aerobic microbes can cause serious infections when they enter the skin.
Some of them have been found in a third of popular brands of tattoo and permanent makeup inks in the United States.
Biologists from the USA, during measurements, discovered 22 variations of anaerobic and aerobic microbes in sealed jars of tattoo and makeup ink, writes the ASM press service.
Some of them may pose a health hazard if they enter the skin, scientists emphasize.
The ability of anaerobic bacteria to multiply in oxygen-poor layers of the skin is a concern.
This indicates that tattoo ink may be a source of bacterial contamination.
Scientists came to this conclusion as a result of studying the properties of 75 popular brands of tattoo and permanent makeup inks.
The presence of microbes and various forms of pathogenic bacteria was noted in 35% of ink samples.
This was also typical for those sealed containers of tattoo and makeup dyes.
Scientists say there is a need for constant monitoring of ink to ensure its microbial safety.
Previously, scientists created AI to accurately predict volcanic eruptions.
