Shellfish Growing Area Risk Categories

By February 1 of each year, we'll update all growing area risk categories. We use a rolling five-year average of vibriosis cases to calculate risk categories.

Category 1: 0.2 or fewer cases attributed to the growing area.

Category 2: 0.3 to 1 cases attributed to the growing area.

Category 3: 1 or more cases attributed to the growing area.
