Some dishonest traders use formalin in food items to give them longevity and an artificially fresh look to attract buyers. Several studies have found that many food items available on the market contain a dangerous level of this harmful chemical.

Formalin may cause several complicated diseases such as kidney failure, liver damage and lung issues. It also may weaken the body's natural defence mechanism against infection. Formalin's adverse effects on pregnancy and the reproductive system have been well studied and proven.

The use of formalin in food amounts to slow poisoning, and such a crime cannot go unpunished. Our authorities should ramp up efforts to contain this despicable phenomenon.
