N.J. Stat. § 4:5-54
The importation of cattle into this State is hereby prohibited, except as provided in section 4:5-69 of this Title, unless such cattle have passed a tuberculin test within thirty days immediately prior to their importation; except, however, that when the State Board of Agriculture has knowledge of specific areas that are sufficiently free of tuberculosis to warrant an exception to this requirement, the board may designate such areas as sources from which cattle may be imported without such test prior to importation, but all cattle imported from such designated area shall be accompanied by a health certificate approved by the chief regulatory official of the point of origin showing the number of animals shipped and certifying that they originated in a modified accredited area and are free from and have not been exposed to contagious, infectious or parasitic diseases, and upon arrival in New Jersey such cattle shall be held in quarantine until officially tuberculin tested at the owner's expense and released by the department.
