US finds no positive animal drug residue in raw milk samples

   

   

   

The US Food & Drug Administration''s (FDA) found no positive animal drug residue tests in pasteurised dairy products headed for sale, according to FDA''s National Milk Drug Residue Database (NMDRD) results.

   

   

Of the nearly 3.76 million milk samples tested for animal drug residues last year, only 731 tested positive for drug residues. Milk samples are tested at various steps in the dairy supply chain, including 1) raw milk at the farm; 2) bulk milk pickup tankers carrying raw milk from dairy farms; 3) pasteurised fluid milk and milk products in package form or bulk; and 4) other random tests throughout the supply chain. The report presents summary data on samples and tests conducted during fiscal year (FY) 2013 (October 1, 2012 to September 30, 2013).

   

   

Twenty-six testing methods were used to analyse the samples for drug residues. Tests were reported on the samples for 10 different groups of families or individual drugs. Of the 731 positive samples, almost 97% were for Beta lactams.

   

   

Only 0.014% of all truckloads of raw milk (445 out of 3.19 million) tested positive for medicinal animal drug residues in fiscal year 2013, down from 0.017% in fiscal year 2012.

   

   

The Grade "A" Pasteurised Milk Ordinance (PMO), the regulations which govern the state regulatory agencies in the implementation and enforcement of their Grade "A" milk safety programme, requires that all bulk milk pickup tankers be sampled and analysed for animal drug residues before the milk is processed. Any bulk milk pickup tanker found positive is rejected for human consumption. The amount of milk disposed of in fiscal years 2009 through 2013 continues a decline that began in fiscal year 2008, according to the NMDRD. The 2013 total was 19.55 million pounds.

   

   

Out of the 467,429 samples of producer milk, defined as raw milk obtained from a farm bulk tank/silo from a dairy farm, 281 (0.06%) tested positive, resulting in the disposal of 339,000 pounds of milk.

   

   

From the 55,408 samples of milk from plant tanks/silos and milk transporters, five tested positive for a drug residue, resulting in the disposal of 240,000 pounds of milk. While of the 40,435 samples of packaged milk products tested after pasteurisation, none tested positive.
