It is difficult to find people who do not know this proverb,” Mache vate bangali”. The link of fish with the heritage of Bengalis is found from the beginning. Pohela Boishakh or any other occasion, the absence of the fish in the food of the Bengalis can be frozen by all arrangements. There are many kind of fish in the river and canal of this riverine country. Fish is the best of nutrients. This is a significant source of animal protein. Fats, calcium, vitamins, iron, phosphorus and other useful ingredients contains in fish. Fish attachments on daily food lists keep the family safe from malnutrition and disease. The city-centric attitude of the current people has forced them to rely on fishermen, markets and dealers to meet the needs of fish.
And with the scope of this dependence some crooked businessmen have been involved in dirty business. Formalin name is now known by the grace of the fish traders. In other countries this is formalin used to protect the dead body, dead animals from infection and traction, to remove the skin tone and make the color durable or explosive. But in our country, its application is even more different. Such as, keep fish or meat for a long time, keep vegetables and fruits fresh etc. Fishes of different parts of the country are collected and these fish tend to reach Dhaka by 2/3 days’ time. Naturally there is a tendency to get lost due to long periods of time. Since the cost and the hassle are more to save the fish in the right way. So fish traders have chosen a method of easy and low cost – formalin application.
These fish offered by formalin are being sold at low prices but Buyers are buying at a higher price and the dealers get extra profit.
It is so much harmful for health. Fishery scientist Dr. Nurullah said that since 2004, the use of formalin began in fish. The presence of formalin found 90% of the fish. The poisonous substance is used outside the fish a few days ago. But due to public awareness and anti-adulteration campaigns, formalin has also been applied in different way. Since it is dissolved in water, the formation of ice cube is made with formalin mixed water. And they are being used in fish, even in fish body is being injected into this formalin. Because of this, there are many types of tests that do not match formalin’s existence in the fish. But, silently, it is already doing damage to the masses. The maximum amount of formalin in the country has been recorded 4.70 ppm, but the study says 0.05 levels of formalin also enter the body through breathing. It causes diseases like asthma, allergies, nerve weakness, and diarrhea. These poisons entered the body with food and causes liver damage, heart disease, nerve problems, kidney disease, digestive problems, mental disorders and many other complex diseases. Not only formalin but also more corruption occurred in the hope of higher profits. The application of unhygienic ingredients like jelly, sago, fatty water, lead shoots, era rotes, magic balls injected shrimp. In these shrimp, these things are shown in larger sizes and more in weight. Before bringing in the market, People try to increase the weight unethical ways.
We have lost international markets for these poorly adulterated activities, although there is a great demand for shrimp in many countries of the world including the United States, Russia, China, Japan, Taiwan, Sweden, Ireland, Germany and the Netherlands. Fish market is made more dangerous by using different types of chemicals and colors. To prove the foreign fish indigenous, to show it fresh and to grow the price fabric blue, mustard oil and specialty chemicals are used. These chemicals are mixed in the preservation drum to cover the crime.

The use of chemicals and medicines in cultivation are not less dangerous. Inner contamination is as harmful as outer contamination. One study found that more than 200 chemicals were found in fish feeds. Tannery waste to dry fish which contains the toxic substance called chromium, is used as a food for fish. The use of poultry wastage in fish firm, Poultry medicine and chemicals are entered in fish. Hildal, DDT, antibiotics, excessive medicine makes the fish poisonous. According to Bangladesh Fisheries Research Institute data from 2005 to 2010, 34 billion dollar shrimp sent back from the European Union for the presence of excessive chemicals and poor food value. These unhealthy foods are pushing us towards many diseases like constipation, liver diseases, blindness, lack of oxygen in the blood, memory loss, reproductive disorders and damage in immune system. Children also victim for complex disease, interrupted physical and mental development. If the voice is not raised against the situation, it will be difficult to protect our future generation.
