A state-run food testing laboratory has found high level of contaminants in dairy products during a recent study.
The National Food Safety Laboratory (NFSL) came up with the revelation of the survey results at a programme at the Public Health Institute auditorium in the capital on Sunday.
The study, titled “Detection of heavy metal, drug and pesticide residue, mycotoxins and microbial contaminants in raw and packaged cow’s milk, curd and feed,” was done on samples of cow fodder, cow milk, packaged milk and curd, collected from 27 upazilas under four districts including Dhaka.
The study was conducted from August to December 2018 by NFSL, with the support of the UN Food and Agricultural Organization (FAO).
A total of 96 samples of raw milk were examined. Among those, nine contained pesticides, 10 had tetracycline, five contained lead and three contained aflatoxins above permissible limits. About 96 percent of the samples had microbial contaminants.
Among 31 samples of packaged milk that were tested, nine contained tetracycline over the permissible limit, while one sample contained lead. Overall, 66-80percent of the packaged milk tested contained various levels of microbial contaminants.
