Microbial Indicators

Microbial indicators are specific microorganisms used to assess the safety of water, food, or environments by signaling the possible presence of harmful pathogens. Because these indicators are easier and faster to detect, their presence suggests that contamination may exist, prompting further testing or precautionary measures. They do not directly cause illness but serve as reliable signs of potential health risks due to microbial contamination. Examples include E. coli for water safety and coliform bacteria for general hygiene checks. Using microbial indicators helps ensure public health by monitoring sanitation levels and preventing disease transmission.
