MANILA, Philippines — A Zambales fisherman and his son died while the fisherman’s wife was in critical condition after they ate a cheap but potentially poisonous fish for dinner, a radio report said late Monday.

Radio dzXL reported that the victims, identified as Jimmy Santos, 55; and son Jimmy Jr., 8, died after feeling dizziness and stomach pains after eating the fish.

Santos’ wife Arsenia, 49, was reported in critical condition at the San Marcelino District Hospital.

The incident occurred at the family’s house in Purok 1 in La Paz village in San Narciso town in Zambales, where the victims had “butete" for dinner.
