Researchers have found traces of detergent in pasteurised milk produced by five companies.
The companies are - Pran, MilK Vita, Igloo, Aarong, and Farm Fresh.
"We tested pasteurised and non-pasteurised raw milk produced by these companies and found detergent and antibiotics in them," Prof ABM Faruque, director of Biomedical Research Centre, told a press conference at Dhaka University on Tuesday.
Dhaka University's Pharmacy Faculty and Biomedical Research Centre jointly conducted the tests.
"The traces of antibiotics that we found were meant for human use. Antibiotics for humans and animals are totally different. We need to stop the use of antibiotics meant for humans on animals," Prof Faruque said.
