4.4.5. Is HAB’s an environmental hazard?


Yes, it is because these events can make people sick when contaminated shellfish are eaten, or when people breathe aerosolized HAB toxins near the beach.

In addition, HAB events can result in the closure of shellfish beds, massive fish kills, death of marine mammals and seabirds, and alteration of marine habitats.

As a consequence, HAB events adversely affect commercial and recreational fishing, tourism, and valued habitats, creating a significant impact on local economies and the livelihood of coastal residents.
