Del. Code tit. 3, § 7331

If it is shown beyond a reasonable doubt that Bang’s disease exists in a herd of cattle, and the owner refuses to sign an agreement placing the owner’s herd under supervision of the Department of Agriculture for the eradication of the disease, or refuses to have any reactors to the Bang’s disease test slaughtered at the direction of the Department, the Secretary of the Department or the Secretary’s agent shall place such premises under quarantine by written notice and no cattle shall be allowed to be removed or any additions made to the herd while it is under such quarantine.
