Something is fishy about the fish from Kerala that has raised concerns in states like Goa, Tamil Nadu, Odisha, Assam, Mizoram, Meghalaya, Nagaland, and Manipur. The Food Safety Department authorities seized nearly about 10,000 kg of formalin-laced fish at the border check post of Arayankavu in Kerala’s Kollam district. Formalin is a toxic substance that is used to preserve dead bodies in mortuaries and prevent their decay.
