Study links higher enteric disease risk to E. coli in high-risk water supplies

A nationwide New Zealand study found no significant overall link between most routine drinking water quality indicators and enteric disease risk, but E. coli signals emerged in higher-risk settings such as surface-water supplies, systems with known source-water risks, and periods of heavy rainfall. The findings suggest that sporadic bacterial enteric disease may sometimes be linked to drinking water contamination, especially in vulnerable system…
