Additional information: | Shellfish harvest is banned when K. brevis exceed 5,000 cells/L. Areas are reopened when K. brevis is <5,000 cells/L and shellfish are <20MU/100g. In this case, harvest was closed for cells concentrations but no toxicity was measured when shellfish were tested to re-open. | |||||||||||
