Key message:

Since the 1970s, the harmful algae phenomenon has increased throughout the world. There is no clear trend in shellfish poisoning events in European waters for diarrheic shellfish poisoning (DSP), and paralytic shellfish poisoning (PSP). Amnesic shellfish poisoning (ASP) occurrences seem to occur more frequently than in the past.
