UNIFORM SHELLFISH SAMPLING PLAN
FOR PARALYTIC SHELLFISH POISON (PSP)

The uniform shellfish sampling plan for Paralytic Shellfish Poison (PSP) testing is revised to address the seasonal nature of toxicity within shellfish growing/harvesting areas. Sampling protocols and product holding requirements are different for summer and winter, and are required to ensure product safety while providing historical and predictive data.

This sampling plan covers only clams, mussels, and oysters. Not covered by this plan are Geoducks, snails, and whole scallops. Species must be sampled and tested as specified in the plan. Samples must be submitted during all months of anticipated harvest and sales.

The plan has four levels. Level One, Two, and Three are species specific. Level Four is non-species specific for individual growing areas and entire classified areas. A growing/harvesting area will remain at Level Three until criteria for all species can be met to move to Level Four.
