LAC 7:XXI.743. Restrictions on Dairy Herds Testing Positive for Mycoplasma Mastitis (Formerly §335)

A. If the second sample from a dairy herd tests positive for Mycoplasma mastitis then that dairy herd shall be placed on a "Mycoplasma restricted list." 1. Individual members, male and female, of any dairy herd placed on the Mycoplasma restricted list shall be tested to identify infected animals. 2. Any animal found to be infected with Mycoplasma shall be either immediately sold for slaughter or branded with a mark acceptable to the department to show that the animal can only be sold for slaughter. If any such animal is sold at a livestock auction market, it shall be kept in quarantine separate from any other cattle. 3. No animal from a dairy herd that is on the Mycoplasma restricted list shall be sold or moved for any purpose other than slaughter unless accompanied by a health certificate showing that the animal has had a negative test for Mycoplasma within the 30 days prior to the date of sale or movement. B. Any dairy herd found to be infected with Mycoplasma shall remain on the Mycoplasma restricted list until all infected animals are removed and bulk tank samples test negative for six months.
