Free from contamination caused by harmful bacteria, viruses, or other microorganisms; surgically sterile.

In tattooing, 'aseptic technique' refers to the strict protocols used to keep the environment, needles, and skin completely sterile to prevent the transmission of bloodborne pathogens.

The story behind the word. The word 'aseptic' is built from the Greek prefix 'a-', meaning 'without', and 'septikos', meaning 'putrefying' or 'rotting'. It was coined in the 19th century during the dawn of germ theory, when doctors realized that keeping surgical environments free of 'putrefying' bacteria dramatically saved lives.
