The project involved the collection of 900 milk samples from dairy producers who had a cull dairy cow residue violation in the past, as well as another 900 milk samples from dairies at large.
NMPF’s Jonker says the idea behind the sampling effort was to determine if the same practices associated with drug residues in cull dairy cows also result in drug residues in milk.

Although residue violations continue to trend downward, the cost of dumping just one tanker of milk is incentive to keep doing better.

Here is a snapshot of the National Milk Drug Residue Data Base’s Fiscal Year 2011 Annual Report*:
• 671 (0.021%) of 3.183 million samples from bulk milk tankers tested positive for animal-drug residues.
• None of the 48,566 samples of pasteurized fluid milk and milk products were positive for residues.
• 395 (0.083%) of 478,533 producer milk samples were positive.
