Toxic cyanobacteria blooms are an increasingly common global problem due to eutrophication, the effects of climate change and increased surveillance efforts in aquatic ecosystems. In Cuba, several ecosystems have been analyzed in the eastern region, demonstrating that this risk occurs to surface and inland waters, due to climatic conditions, mainly in small ecosystems with great human pressures. However, other areas are still unexplored. The objective of this work was to implement a risk management protocol in the San Blas Lagoon, Camaguey, due to the presence of toxic cyanobacteria in the ecosystem, following a community report, with the death of domestic and wild animals; unpleasant odors and dermatological symptoms in humans. A management protocol and community actions were implemented to minimize the impact of toxic cyanobacteria. In this small eutrophic reservoir, the presence of a mixed bloom of toxigenic cyanobacteria was confirmed, being Spherospermopsis torques-reginae the majority, as well as other nine species associated with the production of microcystins, anatoxins and/or cylindrospermopsins were identified. Strategic actions were implemented to contain the risk situation, with the participation of the community and experts, led by the Camagüey Criminalistics Laboratory.
