There's also Amnesic shellfish poisoning from Domoic acid that can cause amnesia, brain damage and death.
And Ciguatera poisoning.
These are eaten by herbivorous fish which in turn are eaten by larger carnivorous fish. The toxins become more concentrated as they move up the food chain.

In a toxic world, it's generally safer to eat lower on the food chain and handle stuff higher up the food chain with more care than you do other foods.
It's not a guarantee of being safe, but it helps lower my blood pressure about such things.
Edit:
Later in the Wikipedia page:
Increasing seasonal temperatures and decreasing salinity levels seem to favor a greater concentration of Vibrio within filter-feeding shellfish of the U.S. Atlantic seaboard and the Gulf of Mexico...

As for the trend, what about the years before 1988?
