Microbial testing of bottled drinking water

1. Total coliform bacteria

After disinfection, the water should be tested immediately and no total coliform bacteria should be detected. Once detected, it indicates improper water treatment. The detection of total coliform bacteria in the water transmission and distribution system and water storage device indicates bacterial regeneration, possible biofilm formation, or contamination of the water inlet and outlet

2. Heat-resistant Escherichia coli

All Escherichia coli that can ferment lactose at 44-45 ℃ are called heat-resistant Escherichia coli. The presence of Escherichia coli indicates recent fecal contamination, and further action should be considered after detection, including further sampling, investigating potential sources of pollution, whether there are reasons such as insufficient water treatment or ruptured water transmission and distribution system pipelines

3. Escherichia coli
