A fish attendant checks round scad, locally known as galunggong and considered as a staple of the poor Filipino, at the Navotas Fishport on Aug. 22. The Department of Health on Wednesday advised the public to report formalin use in fish and other seafood products in the markets after the fisherfolk group Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (PAMALAKAYA-Pilipinas) claimed that some imported seafood products, including galunggong, have been injected with formalin.
