Uruguayan authorities detected once again the presence of cyanobacteria in the waters of the Queguay river (a tributary to the Uruguay River), east of Guichón, in the department (province) of Paysandú.
Toxins in water produced by cyanobacteria killed more than 300 elephants in Botswana this year, officials said on Monday, announcing the result of an investigation into the deaths which had baffled and alarmed conservationists.
An acute case of intoxication with cyanobacteria and cyanotoxins in recreational exposure during an algal bloom in Montevideo beaches, Malvin and Carrasco, was reported in the US National Library of Medicine, National Institutes of Health.
