Office of Indiana State Chemist Inspection Program

What our inspectors do:


Our inspectors serve as the field representatives for our agency. As such, an inspector is charged with effectively communicating and enforcing laws, rules and policies of the agency, inspecting facilities, reviewing records, collecting samples, collecting and documenting evidence, issuring regulatory orders and completing necessary reports for the administrative and laboratory programs.

The program relies heavily on inspections designed to ensure that manufacturers are using GMP's (Good Manufacturing Practices) in making feeds.

We are proud of our inspection staff! Read more about them:
