2. (b) Semen plasma test. This test is approved for use as a supplemental test of boars used for artificial insemination but must be employed with other serological tests. Final classification will be based on the most reactive test procedure.
3. (c) Animals testing positive on any blood test performed will be considered as brucellosis exposed swine and an initial test of the herd of origin will be conducted within a specified time set by a state-federal veterinarian upon consultation with the herd owner unless waived by the designated brucellosis epidemiologist.
4. (d) Reclassification. Animals may be reclassified by the designated epidemiologist when consideration and evaluation of relevant bacteriologic, serologic, or epidemiologic evidence justifies the reclassification.
