The sale of powdered milk has shot up on the market due to crisis of pasteurised milk. Contamination has been detected in 89percent of powdered milk. Liquid milk of dairy farm also is not pure as pesticide aldrin has been found in it. Aldrin was found in pasteurised milk when examined in the laboratory at the Institute of Public Health (IPH) at Mohakhali in the city. Whereas use of aldrin was pr
ohibited worldwide in a declaration two decades ago out of fear for different complicated diseases including cancer. Aldrin is being used also in pasteurised milk approved by government establishment BSTI. IPH sources stated aldrin has been found in five of the six prominent brands of pasteurised milk. This pesticide is not destroyed in heat during cooking. As a result it spread to human body through foods. After entering in the body it destroys function organs in various ways and reduces the disease resistance power. This creates liver, kidney and breast cancer. World Health Organisation banned aldrin well over 24years ago. IPH director Dr Subimol Singha Chowdhury admitted that use of aldrin in packaged pasteurised milk of different famous brands has been permitted by BSTI. In the opinion of people concerned, the farms which possess cattle also produce grass. Aldrin is sprayed at the time of cultivating grass. As a result, the grass is not attacked by pests. A laboratory examinee and quality analyst of IPH said aldrin is found in liquid milk produced specially in different farms at Sathia, Sujanagar of Pabna, Faridpur, Bhangura and Chatmohor, Tarash of Sirajganj, Shajadpur and Raiganj. However, this pesticide has not been found in the milk of any village cow. Persons concerned said instead of date fruits, the producers are mixing formalin, sodium, boric powder and soda to preserve milk. To increase quantity of milk, use of water, starch, sugar and powdered milk is going on since long. After collecting milk, in the past, the people concerned used to sell it on the nearby markets. But there is no such system now-a-days. Rather, local agents of various dairy firms and milk processing companies go home to home to collect milk. They mix various chemicals to keep the milk afresh for long time. People concerned think that milk is being adulterated amid shortage of milk, businessmens intention to make more profit, competition among various companies, weak market management and inadequate cold storage. A recent study on Adulteration of raw milk in the rural Areas of Barisal district shows that formalin is mixed with 10 percent milk, sodium carbohydrate with 20 percent milk during a period between milking and producing it in the market. Besides, water is mixed with 100 percent milk, sugar with 26 percent milk, powdered milk with 14 percent milk and starch with 12 percent milk. Prof Tanwi Chanda of Dairy and Poultry Science Department under Patuakhali Science and Technology University conducted the study. Prof ABM Faroque, a noted pharmacologist of Dhaka University, told daily sun that aldrin is a chemical, which is widely used for killing pests on crops and cultivated grass. And commercial dairy farm and people who are involved in cow rearing are providing these cultivated grass and straw to cows. Cows eat those grass and straw which are mixed with different pesticides, including aldrin. Such pesticides are not destroyed years after years and aldrin is mixed with dairy milk in this way, he added. Prof Faroque also said nobody is artificially mixing the toxic substance with milk but its side effects are comprehensive and it causes kidney and liver cancer, including respiratory tracked infection, among the consumers. On the other hand, powdered milk is full of adulterated and spurious substance. In 2012, sanitary inspectors collected 18 samples to IPH. Of those, 16 samples were found to be adulterated. As such, 88.89 percent powdered milk. Powdered milk must have some components like milk fat 26 percent, paneer 5 percent and milk protein 34 percent. If it is found that the component is lesser than the required percentage, then it will not add any nutritional value to our human health. Sources at Bangladesh Standard and Testing Institution (BSTI) said various factors like milk fat, humidity, milk protein and hygienic atmosphere are taken into consideration to determine the issue of adulteration of powdered milk. Dr Aktarun Nahar Alo of BIRDEM Hospital said people take powdered milk in order to get high level protein but a section of unscrupulous businessmen withdraw fat from such milk. Dr Subimol Sinha Choudhury said the samples of powdered milk sent by the sanitary inspectors from rural areas have been found to be adulterated. Besides, aldrin was found in liquid milk being sold on the market. He said aldrin is a banned item and is not supposed to be available in the market. He spoke on the need for conducting investigation into the matter. Sanitary Inspector Md Jinnah of Sirajganj Civil Surgeons office said they collect samples from various districts and send those to IPH. He said case is filed with the judicial magistrates court if the samples are found to be adulterated. Besides, the mobile courts launch drive and punish the accused person. Meanwhile, it is alleged that liquid milk is being contaminated as the cows are being allowed to graze aldrin mixed grass.
