Section 80. Handling of LBM positive laboratory results

When birds in a LBM test positive for AI, the LBM shall close. Such LBMs shall depopulate and perform C&D. The State Veterinarian shall approve depopulation and disposal methods. The State Veterinarian may at his discretion approve a plan to allow the LBM up to five calendar days from the time of notification of positive test results from an approved laboratory to sell down its poultry inventory. Additional birds shall not enter the LBM after notification of positive status for AI or during the sell-down period.

Prior to reopening, the LBM shall be inspected by the State Veterinarian. Environmental samples shall be taken for testing at this time, but the LBM may be allowed to reopen while it awaits environmental test results. If results are positive for AI, the LBM shall again close (with up to five days to permit sell down, if appropriate) and shall again perform C&D procedures within 24 hours of the depopulation, followed by inspection and retesting.

Samples that initially test positive for AI at an approved laboratory shall be submitted to the NVSL for confirmation.

Any LBM that has a positive AI test shall undergo monthly testing.

After three consecutive negative tests, the LBM may be allowed to return to a schedule of quarterly testing and quarterly closures.

When AI-positive birds are in the LBM or delivered to the LBM, an investigation shall be initiated by the State Veterinarian. LBM records shall be presented to the State Veterinarian for epidemiologic investigation.
