The Ministry of Science, Technology, and the Environment (CITMA) of Cuba issued a maximum alert due to the massive arrival of sargassum on the shores of Guantánamo province in the eastern part of the country. The high concentration of these marine algae poses health risks because of the release of toxic gases such as hydrogen sulfide and ammonia during their decomposition. In areas such as Baitiquirí and El Guanal, on the southern coast of Guantánamo, beaches have been transformed into fields of decomposing sargassum. Fishermen and locals report unbearable odors, respiratory issues, the death of marine species, and corrosion of metal structures. The alert comes amid a situation that is already severely affecting communities in eastern Cuba.
