Researchers again claimed to have found traces of antibiotics in 10 samples of pasteurised and unpasteurised milk produced by several companies, reports UNB.
Ten samples -- seven pasteurised and three unpasteurised -- were again tested last week, said a press release signed by professor ABM Faruque, the former director of Dhaka University's Biomedical Research Centre.
Pasteurised products of Pran, Milk Vita, Igloo, Aarong, and Farm Fresh were tested, the statement released on Saturday said.
New tests found four types of antibiotics in three samples, three types of antibiotics in six samples and two types in one sample.
"We'll try to publish results of these tests and others in future for the sake of the people," professor Faruque said.
He requested the authorities concerned to run regular tests on the products and improve their qualities.
Professor Faruque could not be reached for comments for this report.
Earlier on 25 June, researchers announced about finding traces of detergent and antibiotics in samples of pasteurised and unpasteurised milk of Pran, Milk Vita, Igloo, Aarong, and Farm Fresh.
All seven samples of pasteurised milk contained antibiotics used to treat humans, professor Faruque had said.
Detergent was detected in three samples of pasteurised and an unpasteurised one, he added.
