Event name: US-07-010
Nature of the harmful event:
Seafood toxins
Event directly affected:
Shellfish , Humans
Toxicity detected: Yes (Approximate range: Area 1: 0-486ug stx eq/100g; Area 2: 0-776)
Associated syndrome: PSP
Unexplained toxicity: Yes (Floating barrel covered in mussels, recovered in Area 1, resulting MBA showed PSP levels at >18k ug stx eq/100g - higher than inshore values in Maine. Suspect barrel originated in the Canadian Maritimes)
Species implicated in toxin transmission (transvector): Mussels from barrel were eaten by a family of 4, resulting in intoxification of all 4, and hospitalization of 3.
Report the outcome of a monitoring programme: Yes (Maine Department of Marine Resources)
Event occurred before in this location: Yes
