Paralytic Shellfish Poisoning Forecast

Predictions from the Paralytic Shellfish Poisoning (PSP) Forecast are not representations of fact or guarantees of future toxicity levels, and this forecast cannot be used to determine whether seafood is safe to eat or harvest. Determinations of safety should be based on shellfish toxicity testing. This forecast is the product of a collaboration between the Maine Department of Marine Resources and Bigelow Laboratory for Ocean Sciences.
