Bangladesh, food adulteration is considered as a “Silent Killer” now a day. It is very difficult to find a sector of food industry in Bangladesh which is free of adulteration. From raw vegetable and fruits to milk and milk products, fish, meat and processed food–every food item is contaminated. Contamination of foods with toxic chemicals like carbide, formalin, heavy metal, chemical, textile colors, artificial sweeteners, DDT, urea and so on pose a serious threat to public health, especially in a country like Bangladesh through damaging vital organs like liver, kidney, pancreas etc.
