Fish contaminated with formaldehyde
Formaldehyde is a substance that has the ability to disinfect and prevent bacteria from growing. This substance is easily soluble in water and has a pungent odor. Formaldehyde is a substance banned from use in food. However, some people still deliberately use this substance to extend the shelf life of food.

Meanwhile, consuming 0.3 to 0.5 grams of nitrite can cause poisoning. Nitrite intake greater than 3 grams will be life-threatening.
