Please keep in mind when reading what follows, that we rigorously employ guidelines and controls in order to prevent exposure to bloodborne pathogens. These guidelines and controls are called Universal Precautions and are published by the Centers for Disease Control (CDC).
Our Tattooists (and tattoistas) are certified in the continuing education in the prevention of disease transmission in tattooing. All instruments are sterilized using a closely monitored autoclave which is the same type of equipment used by HealthCare Institutions in the USA.
The needles we use to Tattoo are Single-Use. I also use individual portions of Tattoo inks, in sanitary Single-Use containers for each client. The needles, containers and the remainder of the ink are DISPOSED of properly and immediately following the Tattoo procedure.
To prevent cross-contamination I maintain an environment that is sanitary during all Tattooing procedures.
In addition, upon completion of the Tattooing session we explain to each client how they should care for their new Tattoo, as well as provide a written summary of that explanation. Of course those clients are encouraged to contact us with any questions or concerns.
Can a customer get hepatitis B from getting a tattoo?
In 1960, New York City health officials blamed 30 cases of hepatitis B and one death on tattoo artists. Allegedly, the problem was caused by improper instrument sterilization and using contaminated pigments. Two New York tattoo artists appealed the legal hassle and it went on until 1966, the Court of Appeals affirmed the decision of the lower court. 
Of the 13,387 annual cases of hepatitis detailed in the most recent CDC report, 12 are associated with tattoo studios. By comparison, 43 cases — or better than 300% more — are associated with dental offices. 
NOTE: I have personally talked with one of the Tattoo Artists who was put out of business due to the above ruling, what they are not telling you is, there was also a bad shipment of seafood, and not every one infected with Hepatitis B had tattoos.
Besides NYC where else in the U.S. has our personal freedoms been taken away concerning us getting a Tattoo? Albuquerque, New Mexico, Connecticut, Florida, Kansas, Massachusetts, Oklahoma, South Carolina, and Vermont. 
NOTE: Today all 50 states have legalized Tattooing, for now, my personal opinion is because they have realized, via licensing and taxation, they earn money. However, some if not most counties in the State make it extremely difficult, via regulations, in some cases practically impossible for talented artists that know what they are doing, to make living. In some cases it is easier to work outside of government’s guidelines.
