Coliform index
Coliform Index
The Coliform Index (pronounced: koh-luh-form in-deks) is a method used to determine the sanitary quality of water and food. It measures the presence of coliform bacteria, which are a broad class of bacteria found in the environment, including the feces of man and other warm-blooded animals.
Etymology
The term "coliform" comes from the Greek word "kolon" meaning colon, and the Latin word "forma" meaning shape. This is due to the fact that these bacteria are rod-shaped and are often found in the colon of warm-blooded animals.
