Identification of a positive animal using the organism detection test during the certification herd test will result in the loss of certification status. The next negative test will qualify the herd for Level 1 certification.
If a positive animal is detected on any other test for Johne's disease during the current certification period other than by an organism detection test, the herd's certification will be suspended pending a confirmatory organism detection test of that animal.
