Not clean or hygienic, often leading to health risks.
The kitchen was deemed unsanitary due to the presence of mold and dirt.
Unsanitary → It is formed from "un-" (meaning not) and "sanitary" (from Latin "sanitas", meaning health). The word "unsanitary" means not healthy or not conducive to health.
Think of 'not' ('un-') being added to 'healthy' ('sanitary') — that's why unsanitary means something that is not healthy.
