The Department may promulgate and adopt reasonable rules and regulations to prevent the spread of any contamination or contagious or infectious disease within this State. If the condition so warrants, the Director may request the Governor to issue a proclamation quarantining an affected municipality or geographical district whereby all animals of the kind diseased or contaminated would not be permitted to be moved from one premises to another within the municipality or geographical district, or over any public highway, or any unfenced lot or piece of ground, or from being brought into, or taken from the infected or contaminated municipality or geographical district, except by a special permit, signed by the Director. Any such proclamation shall, from the time of its publication, bind all persons. Within one week after the publication of any such proclamation, every person who owns, or who is in charge of animals of the kind diseased or contaminated within the municipality or geographical district, shall report to the Department the number and description of such animals, their location, and the name and address of the owner or person in charge, and during the continuance of the quarantine to report to the Department all cases of sickness, deaths or births among such animals.
If the condition so warrants, the Director may declare a temporary prohibition on the sale, movement, or exhibition of certain types of animals in order to prevent or reduce the spread of any contamination or disease in this State. The declaration shall be for a period not to exceed 30 days, but the declaration may be extended in increments not to exceed 30 days if the condition so warrants.
