Ghaziabad, Aug 13 (PTI): 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.

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 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 the 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.

The test report of Kolkata's Central Laboratory has been submitted to the District Magistrate Vimal Kumar Sharma, who in turn will forward it to the Commissioner to seek his approval to initiate legal action against Mother Dairy, the official said.

Meanwhile, Marketing head of Mother Dairy, Sandeep Ghosh said that they were yet to receive re-test report of the Kolkata-based Central Laboratory.

As there were contradictions between the two test reports, Mother Dairy will approach appropriate legal forum to challenge them, Mr Ghosh added.
