KOTA KINABALU - Three more people were warded at the Queen Elizabeth Hospital here after consuming red tide-infected toxic mussels, bringing the number of victims to 46.
The health department expects more people who had bought the mussels at the Inanem night market here to come forward for treatment.
The red tide phenomenon claimed its third victim on Wednesday when a 23-year-old foreigner from Kampung Inanam Jaya died from suspected poisoning after consuming shellfish bought at the market.
The shellfish was said to have been sold at just RM1.50 (S$0.60) per plastic bag.
Sabah health department director Dr Christina Rundi said: "We don't know how many people actually consumed the clams but we advise those who ate them to seek treatment, whether or not they have symptoms."
The initial symptoms include tingling lips and tongue, a sensation of "pins and needles" on the skin, followed by loss of control of arms and legs, and breathing difficulty.
The red tide warning was first issued by the Fisheries Department on Dec 12 last year.
The phenomenon is triggered by a deadly algae bloom, which produces toxic or harmful effects to marine life and turns the water red.
