Mass Fish Die-off in Samut Sakhon Prompts Health Warning

On November 10, 2026, officials in Samut Sakhon province launched an investigation following the discovery of a large number of dead fish floating in the Heng Neramit Canal, located in Ban Ko sub-district. The incident, which has caused a significant foul odor in the area, involves various species, including blackchin tilapia, sucker fish, snakehead fish, and tilapia. Local authorities estimate that the fish have been dead for approximately four to five days. Provincial fisheries and environmental officials have collected water and fish samples to determine the exact cause of death, specifically investigating whether the fish were killed by water contamination or other environmental factors. In the meantime, the Ban Ko Subdistrict Administrative Organization has deployed teams to remove the carcasses from the canal to mitigate health risks and reduce the pervasive smell affecting local residents. Officials have issued a stern warning to the public, advising against catching or consuming any fish found in the area, as it remains unconfirmed whether the carcasses contain harmful contaminants. Residents and visitors are encouraged to avoid the immediate vicinity of the canal until the cleanup is complete and the water quality analysis is finalized. Further updates are expected once laboratory results are available.
