Title 12 - Department of Agriculture
Article 12:17 - Dairy plants and manufactured grade milk
Chapter 12:17:03 - Quality requirements
Section 12:17:03:23 - Test for drug residue

The milk buyer shall screen all bulk milk pickup tankers for beta lactam drug residues. In addition, the milk buyer shall employ a random bulk milk pickup tanker sampling program which screens for other drug residues. The screening program shall include at least four samples collected in at least four separate months during any consecutive six months. Samples collected under the random sampling program shall be analyzed as specified by the secretary.

The bulk milk pickup tanker must be sampled at the dairy plant, unless approved by the secretary, after milk from the last producer has been picked up and before any additional commingling. The milk shall be thoroughly agitated and sampled using approved sampling procedures. The sample analysis must be completed before the milk is processed. Bulk milk pickup tanker samples that are positive for drug residues shall be retained upon the request of the secretary. The milk buyer shall also record all sample results and retain the records for one year.

If a bulk milk pickup tanker is found to be positive for drug residues, the secretary shall be immediately notified of the results and the ultimate disposition of the raw milk.

The producer samples from the bulk milk pickup tanker found to be positive for drug residues shall be individually tested to determine the farm of origin. The samples shall be tested at an officially designated laboratory capable of performing the specific test. The milk buyer shall discontinue further pickups from the individual producer whose milk tested positive for drug residues until subsequent tests are no longer positive for drug residues.
