Dead Fish Mystery in Yucatán: Toxic Algae Suspected

Chuburná, Yucatán — The sudden appearance of hundreds of dead fish along the coast of Chuburná port in the municipality of Progreso has sparked alarm among residents and tourists. The incident follows similar reports from the nearby area of Chelem, where octopuses and other marine species were found stranded in recent days.

Potential Link to Toxic Algae Bloom

Local authorities have suggested that the phenomenon may be tied to a bloom of toxic algae, which, while not yet officially classified as a "red tide," could pose risks to marine life and humans. Contact with these algae may cause skin irritation, while consuming contaminated seafood could lead to severe stomach infections.

The Center for Research and Advanced Studies of the National Polytechnic Institute (Cinvestav) stated that the observed conditions could indeed be indicative of a red tide, though further studies are required to confirm the exact cause.

Precautionary Measures Issued

Progreso Mayor Erik Rihani urgently advised visitors and residents to avoid entering the ocean in affected areas and to refrain from consuming fish or other seafood that may have recently washed ashore. The water in the region has also displayed an unusual brown discoloration, a common sign of microalgae presence.

Tourism operators in Chuburná’s popular "Isla Columpios" area announced via social media the suspension of all scheduled activities and tours until further notice as a precautionary measure.

Ongoing Monitoring and Public Advisory

Authorities continue to monitor the situation, while marine biology experts urge the public to stay informed through official channels to avoid health risks. Further updates are expected as investigations progress.
