An Environmental Health Specialist, or "sanitarian" is a public health professional who protects public health from detrimental conditions in the environment through education, consultation, and regulation.  Environmental Health Specialists are college graduates with training in public health, sanitary science, or one of the physical sciences.  An Environmental Health Specialist works with other professionals in their community to provide a safe and healthy environment.

After one year of environmental health experience, an Environmental Health Specialist is eligible to take a written examination for professional registration as a Registered Environmental Health Specialist/Sanitarian (REHS or RS) by the State of Minnesota.
