| Objective. Ostreopsis ovata and Ostreopsis siamensis are tropical unicellular algae that have been found recently in the Mediterranean. Both of these dinoflagellates produce palytoxin (PTX)-like toxins that are powerful vasoconstrictors in mammals. Since 2003, Ostreopsis blooms in Italy and Spain have been accompanied by reports of respiratory problems and skin/mucosa irritation in persons in contact with toxic microalgal cells (epiphytes, plankton, or sea spray) or associated toxins. Methods. In France, a surveillance network has been set up to monitor water conditions and to protect swimmers from contamination due to Ostreopsis. Results. Between 2006 and 2009, a total of nine blooms were observed on the French Mediterranean coast including five that led... |

| An initial surveillance system of Ostreopsis ovata was set Lip along the Mediterranean coast in the summer of 2007. To Strengthen and adapt this system, we reviewed the information available for a health risk assessment of this monocellular species of algae that produces palytoxin and is increasingly observed in the Mediterranean Sea. Since 2002, this species has been reported to be responsible for many human cases of irritation, Cough, fever and respiratory problems in Europe. It is not Currently possible to determine if palytoxin causes these health effects, which follow aerosol inhalation. Ingestion of contaminated seafood may lead to very serious poisoning, but no such case has yet been described in Europe. A "dose-response' relation cannot be... |
