Filthy conditions forced the closure of a tattoo and piercing studio in Alberta, Canada. It was the second closure in the area in the past three months! See the article here.
Who knows how long the studio maintained their inappropriate procedures before being shut down? Or how many clients may have suffered infections as a result? Fortunately, those businesses were forcibly closed. But, how many others are still operating without following appropriate hygiene practices? Body art is not regulated in all areas, and even where laws exist, they aren't always enforced. That's why YOU as a consumer need to be educated. So when you go into a studio you can make a solid evaluation of the premises and practices to be sure you will be safe.
You can learn everything you need to know about this in The Piercing Bible
. Chapters 5-9 all contain information on how to evaluate piercer, studio premises, and even the body jewelry. Be safe; educate yourself!
