The Mississippi Department of Marine Resources (MDMR) Microbiology Laboratory plays a vital role in protecting public health and maintaining the integrity of Mississippi's coastal waters through comprehensive fecal coliform montioring. As part of the state's Shellfish Sanitation Program, the laboratory conducts routine microbiological analysis of water samples collected from designated shellfish growing areas thoughtout Mississippi coastal waters. Fecal coliform testing serves as a critical indicator of water sanitation and quality. Data generated by the laboratory is used to assess environmental conditions, determine shellfish harvest classifcations, and support timely management decisions regarding area openings and closures. 

This presentatioin will outline the laboratory's testing approaches, including the Most Probable Number (MPN) method, quality assurance protocols, and compliance with National Shellfish Sanitation Program (NSSP) standards. It will also emphasize how the laboratory's results support public heatlh and safety of commerically harvested shellfish. Through its committment to scientific accruacy and public service, The MDMR Microbiology Laboratory demostrates the important connection between microbiology and public safety in the Mississippi Gulf region.
