Country: SPAIN
Nature of the harmful event:
High Phyto concentration , Foam/Mucilage in the coast , Other ( People near the beach suffered respiratory problems)
Event directly affected:
Toxicity detected: No
Associated syndrome: OTHER
Unexplained toxicity: No
Species implicated in toxin transmission (transvector):

Location: Latitude: 41.556667, Longitude: 2.508333
General location information: Llavaneres, Catalonia, NE Spain
HAB Area code(s): ES-22
Additional location information:
Bloom event dates (yyyy/mm/dd): Start: 2004-08-11,
Quarantine levels dates (yyyy/mm/dd):
Additional date-related information: During the same dates high cell concentrations (up to 100 000 cells/L) were also detected northward (Castell and Tossa de Mar) and southward (Sitges) of this locality. However, we don't have any knowledge on respiratory problems at those beaches.


Causative organism known: Yes
Causative Species/Genus: Ostreopsis siamensis (23,101 cells/L)
Co-Ocurring Species/Genus:
Chlorophyll concentration, if known: µg/l
Additional bloom information: We know from this incident due to an emípidemiologic study done by the Sanity Department because about 40 people in the beach suffered respiratory problems.During the days previous to the event, magroalgae floated on the water and white and brown scums we
