Detergent and frozen fat have been found by the Kolkata-based Central Laboratory during re-tests of milk samples collected by district Food and Drugs Administration (FDA) department from Mother Dairy booths here.

Ghaziabad FDA yesterday received the re-test reports, from the Kolkata-based laboratory, according to which both samples of “full cream” and “toned” milk were found containing frozen fat and detergent, FDA official Vineet Kumar said here today.

District FDA teams had collected samples of “full cream milk” on January 11 from a Mother Dairy booth situated at H-Block in Govindpuram, while samples of toned milk were collected on January 30 from the booth situated at 100 feet road in Loni, in the district, he said.

Both the samples were sent to State Laboratory at Meerut for testing, where they were found it to be of sub-standard as they contained “low fat”.

But, Mother Dairy officials challenged the test reports and demanded for a re-test of samples at Kolkata-based Central Laboratory, he said.
