Where to report unsanitary practices performed by nail shop

Question:

Recently I had my nails done at nearby nail shop. During practices, a staff there not only cut my cuticles but also rendered service with unsanitary tools. As a result, I ended up with infections on my three fingers and have been prescribed antibiotics. For this issue, who should I talk to?
 

Answer:

For health/hygiene issues, please contact local authorities where said nail shop locates.
