Authorities in Cadiz City, Negros Occidental are investigating the case of at least 70 people who suffered from allergic reaction reportedly from the fish they have eaten.
At least two residents had to be taken to the hospital.
In an advisory posted on the local government’s Facebook page on April 7, 2026, the city said the symptoms experienced by the residents were consistent with histamine fish poisoning.
“Initial investigation findings suggest that the symptoms experienced by the affected individuals such as rashes, itching, flushing, and breathing difficulty are consistent with histamine fish poisoning, which may occur when fish is not properly handled or stored at appropriate temperatures after catching. Reports have disclosed that the fish was transported from Iloilo and originally sold to local dried fish producers to be processed as dried fish, but later was sold as fresh in the local market. Validation regarding this report is still ongoing,” the advisory read.
The city said the patients have received medical attention and are being monitored closely.
The Cadiz City Health Office and the City Agriculture Office have collected fish samples and have submitted them for toxicological examination.
Residents have been advised to:
- Purchase fish and seafood from reputable and properly regulated vendors
- Ensure that fish is fresh, properly stored, and adequately cooked
- Immediately seek medical attention if symptoms such as rashes, dizziness, or difficulty in breathing occur after food consumption
The Negros Occidental Provincial Health Office is also investigating reported cases in the town of Hinigaran.
Dr. Girlie Pinongan, head of the Negros Occidental Provincial Health Office, advised the public to go to the nearest health facility should they experience symptoms.
“Pumunta lang sa nearest health facility before lumala ang sitwasyon. Make sure ang kanilang na-buy na mga isda ay fresh,” she said.
