N.J. Stat. § 4:5-11
When, by reason of the locality of an infected animal or herd within a city, or by reason of frozen ground or extreme heat, it is, in the judgment of the department of agriculture, inexpedient or impossible to bury any such dead or slaughtered animal on the premises, the department may authorize any veterinarian acting for it to slash the skin and cut the flesh of the animal, and, either under his direct oversight, or that of a city board of health, or contractor for the disposal of dead carcasses, to give over the same to the use of a bone-boiling or glue or other establishment for the disposal of dead animals, but in no case shall the dead animal, or any part thereof, be disposed of for food, and any such disposal of the same shall make the party concerned guilty of a misdemeanor and punishable by a fine of not more than one hundred dollars, or imprisonment in the county jail for a period not exceeding six months.
