Shellfish gathering water quality monitoring
Summary of faecal coliform counts from routine monitoring benchmarked against the recreational shellfish-gathering water quality criteria. Both criteria must be exceeded (values in red) to fail guidelines.
- Median faecal coliform content of samples taken over a shellfish-gathering season shall not exceed a Most Probable Number (MPN) of 14 cfu/100 mL, and
- Not more than 10% of samples should exceed an MPN of 43 cfu/100 mL (using a five-tube decimal dilution test)
See water quality criteria (MfE/MoH 2003) for more information.
