The National Food Safety Laboratory (NFSL) revealed its survey results at a programme at the Public Health Institute auditorium in Dhaka today.
The survey was conducted on samples of cow fodder, cow milk, packaged milk and curd, collected from 27 upazilas under four districts including Dhaka.
Cow fodder samples were found to be contaminated with different harmful chemicals, such as pesticides, lead, chromium, tetracycline, enrofloxacin, ciprocin, and aflatoxin, the survey revealed.
