Interstate Movement Guidelines

 

Sample Collection Guidelines

For the premovement testing of lactating dairy cattle, samples are to be collected by an accredited veterinarian, a state-licensed veterinarian, or a sample collector approved by the appropriate state animal health official. Designated individuals on production sites can be trained to collect milk samples and nasal swab samples for diagnostic testing. Samples must be collected under the supervision of a licensed or accredited veterinarian or as determined by the respective State Animal Health Official.

Samples for interstate premovement testing need to be submitted to an approved National Animal Health Laboratory Network (NAHLN) Laboratory for testing. NAHLN laboratories will conduct NAHLN-approved PCR testing: IAV matrix, H5, and optionally 2.3.4.4b. 

Sample Type

Milk samples from individual cows. Each quarter should be sampled and combined into one sample container for submission to the laboratory. Submissions must be between 3-10 ml of milk per animal.

Pooling of milk samples can be done only at the laboratory.

Number of Samples Required

Groups of 30 or fewer animals moving interstate, all animals being moved must be tested.

Groups of more than 30 animals are moving interstate, then at least 30 animals total must be tested.

Timing 

Sample collection and testing must take place no more than seven (7) days prior to interstate movement.
