In brief
The Department of Fisheries confirmed that the red‑tide organism is still detected from Belait to Brunei‑Muara between Oct. 30 and Nov. 3, and warned residents against consuming small fish or shellfish. A Facebook post from the Borneo Bulletin, however, says the algal bloom is non‑toxic and will not harm marine life. The two accounts are yet to be reconciled by independent tests.
On Nov. 4 officials announced that the red‑tide organism continues to pepper Brunei’s coastal waters, with laboratory tests from Oct. 30 to Nov. 3 confirming its presence in the Belait, Tutong and Brunei‑Muara districts.
The Department of Fisheries, citing the latest monitoring and laboratory analyses, urged the public not to collect or eat small fish species, shellfish, or any dead fish, warning that toxins produced by the organism could pose a health risk.
The message, reported by the official media Pelita Brunei, came as part of the government’s ongoing safety briefings on the persistent phenomenon in Brunei Bay and surrounding waters.
Contrastingly, a Facebook post from the Borneo Bulletin’s community page noted that scientists have confirmed the algal bloom as non‑toxic and that it will not kill marine life that contacts it.
Neither the government nor the Bulletin have yet provided further laboratory details, leaving the exact toxicity of the current bloom unconfirmed. Both sources highlight the continued presence of the organism, but diverge on whether the recent bloom threatens public health or marine ecosystems.
