Manila, Philippines – The Bureau of Fisheries and Aquatic Resources (BFAR) in Negros Occidental is investigating an incident of food poisoning affecting several residents of Cadiz City after consuming Aloy or Tulingan fish.
According to reports from the City Health Office, the individuals experienced chest tightness, difficulty breathing, rashes, and redness on some parts of the body.
Based on the preliminary investigation report, these symptoms tested positive for Histamine Fish Poisoning, which commonly occurs in Scombroid fish containing naturally high levels of histidine or toxins.
Scombroid species, including Tulingan, are high in the enzyme histidine decarboxylase.
If these fish are not properly handled or immediately kept in the cold chain (such as icing at 0°C) after being caught, this enzyme converts histidine into high levels of histamine.
Thus, even if the fish is washed, boiled, or thoroughly cooked, the toxic bacteria remain active and can poison anyone who consumes it.
In a statement released by the local government of Cadiz, the investigation revealed that the fish were originally intended to be sold to dried fish producers, but were later sold fresh in wet markets.
Authorities are still confirming these reports.
Meanwhile, the affected residents have already received medical attention.
The City Health Office, City Agriculture Office, and other relevant agencies are focusing on tracing the exact source of the fish that were consumed.
Samples of the Tulingan fish have also been collected and sent for toxicological examination to determine the precise cause of the food poisoning.
Meanwhile, the Cadiz City Government reminded all vendors and the public to always ensure that the food they sell and consume is safe.
