Health Hazards of Tattoos | Mexican Tattoo Design
Because it requires breaking the skin barrier, tattooing may carry health risks, including infection and allergic reactions. In the United States, for example, the Red Cross prohibits a person who has received a tattoo from donating blood for 12 months (FDA 2000), unless the procedure was done in a stateregulated and licensed studio, using sterile technique. Not all states have a licensing program, meaning that people who receive tattoos in those states are subject to the 12-month deferral regardless of the hygienic standards of the studio. Similarly, the UK does not provide certification for tattooists, and so there is a six month waiting period without exception.
Modern western tattooers reduce such risks by following universal precautions, working with single-use items, and sterilizing their equipment after each use. Many jurisdictions require that tattooists have blood borne pathogen training, such as is provided through the Red Cross and OSHA.
Infection
Since tattoo instruments come in contact with blood and bodily fluids, diseases may be transmitted if the instruments are used on more than one person without being sterilized. However, infection from tattooing in clean and modern tattoo studios employing single-use needles is rare. In amateur tattoos, such as those applied in prisons, however, there is an elevated risk of infection. To address this problem, a program was introduced in Canada as of the summer of 2005 that provides legal tattooing in prisons, both to reduce health risks and to provide inmates with a marketable skill. Inmates were to be trained to staff and operate the tattoo parlors once six of them opened successfully.
Infections that could be transmitted via the use of unsterilized tattoo equipment or contaminated ink include surface infections of the skin, herpes simplex virus, tetanus, staph, fungal infections, some forms of hepatitis, tuberculosis and HIV. Even if the needles are sterilized or never have been used, it is important to understand that in some cases the equipment that holds the needles cannot be sterilized reliably due to its design. People with tattoos are nine times more likely to be infected with hepatitis C, according to a study by Robert Haley, MD, chief of epidemiology at the University of Texas Southwestern Medical Center in Dallas. Hepatitis C is
spread by infected blood and infected needles, which is the virus' connection with tattooing.
No person in the United States is reported to have contracted HIV via a commercially-applied tattooing process. Washington state's OSHA studies have suggested that since the needles used in tattooing are not hollow, in the case of a needle stick injury the amount of fluids transmitted may be small enough that HIV would be difficult to transmit. Tetanus risk is reduced by having an up-to-date tetanus booster prior to being tattooed. The Centers for Disease Control and Prevention states that no data exist in the United States indicating that persons with exposures to tattooing alone are at increased risk for HCV infection. In 2006, the CDC reported 3 clusters with 44 cases of methicillin-resistant staph infection traced to unlicensed tattooists. According to the Centers for Disease Control, some studies have found an association between tattooing and HCV infection. The CDC is currently conducting a large study to evaluate tattooing as a potential risk.
Allergic reactions
Perhaps due to the mechanism whereby the skin's immune system encapsulates pigment particles in fibrous tissue, tattoo inks have been described as "remarkably nonreactive histologically".
Allergic reactions to tattoo pigments are uncommon except for certain brands of red and green. People who are sensitive or allergic to certain metals may react to pigments in the skin with swelling and/or itching, and/or oozing of clear fluid called serum. Such reactions are quite rare, however, and some artists will recommend performing a test patch.
For those who are allergic to latex, many artists are using nonlatex or will use non-latex gloves if asked.
There is also a small risk of anaphylactic shock (hypersensitive reaction) in those who are susceptible, but the chance of a health risk is small.
Due to the fact that laser removal of tattoo ink causes a release of ink into the bloodstream the risk of anaphylactic shock is also present during removal.
