N.C. Gen. Stat. § 106-316: Counties authorized to purchase and supply serum.

If the county commissioners of any county in the State deem it necessary to use anti-hog-cholera serum to control or eradicate the disease known as hog cholera, they are authorized within their discretion to purchase from the State Department of Agriculture and Consumer Services sufficient anti-hog-cholera serum and virus for use in their county and supply same free of cost to the residents of the county, or pay for any portion of the cost of said serum, the remaining portion to be paid by the owners of the hogs.

The use of anti-hog-cholera serum and virus and the quarantine of diseased animals shall remain under the supervision of the State Veterinarian.

Nothing in this section shall in any way interfere with existing laws and regulations covering the use of anti-hog-cholera serum and virus and the quarantine and control of contagious diseases, or any laws or regulations that may become necessary in the future. (1919, c. 132; C.S., s. 4881; 1997-261, s. 109.)
