Fish brought from market is heavily contaminated with formalin, the chemical used to preserve dead bodies in mortuaries. The carcinogen, a substance which causes cancer, is used to prevent deterioration of fish. The toxic substance also affects the functioning of internal organs.
It is an antimicrobial agent used to prevent decomposition of fish and to retain its natural taste.
