SUNESEN, Inés; LAVIGNE, Andrea S; GOYA, Alejandra  and  SAR, Eugenia A. Episodios de toxicidad en moluscos de aguas marinas costeras de la provincia de Buenos aires (Argentina) asociados a algas toxígenas (marzo de 2008-marzo de 2013). Bol. Soc. Argent. Bot. [online]. 2014, vol.49, n.3, pp.327-339. ISSN 1851-2372.

Since a project of monitoring toxigenic microalgae and toxins in shellfish started in 2008, carried out along the coast between San Clemente del Tuyú and Mar Azul (Northern Zone) and Bahía Anegada (Southern Zone) of the Province of Buenos Aires, four outbreaks of toxicity for paralytic shellfish toxins (PSP) and eight outbreaks for lipophilic shellfish toxins (DSP / not determined) were recorded. The results were used as technical tool from which the implementing authority (Dirección Provincial de Pesca of the Ministerio de Asuntos Agrarios de la Provincia de Buenos Aires) founded eleven decisions to impose closures and one sanitary alert to the consumption, extraction and commercialization of shellfish. Three of the PSP outbreaks occurred in the Northern Zone associated with Gymnodinium catenatum. The fourth episode occurred in Puerto Quequén associated with Alexandrium tamarense. In the same area there were three DSP toxicity events, and associated species were Dinophysis acuminata and D. caudata. The remaining five episodes of toxicity for lipophilic toxins occurred in the Southern Zone, in one or more of the three sanitary areas classified as A by SENASA, and none of them could be associated with any of the known toxigenic species.
