No owner, railroad or other common carrier may, when transporting any animal, allow that animal to be confined in any type of conveyance more than 28 consecutive hours without being exercised as necessary for that particular type of animal and without being properly rested, fed and watered; except that a reasonable extension of this time limit shall be granted when a storm or accident causes a delay. In the case of default of the owner or consignee, the company transporting the animal shall exercise the animal, when necessary for the particular type of animal and for the proper resting, feeding, watering and sheltering of such animal, and shall have a lien upon the animal until all expenses resulting therefrom have been paid.
Any person who intentionally or negligently without jurisdiction of law detains a shipment of livestock long enough to endanger the health or safety of the livestock is liable to the owner for any diminution in the value or death of the livestock.
Authorities detaining a livestock shipment shall give priority to the health and safety of the animals and shall expeditiously handle any legal violation so that the intact shipment may safely reach its designated destination.
A person convicted of violating this Section or any rule, regulation, or order of the Department pursuant thereto, is guilty of a Class B misdemeanor. A second or subsequent violation is a Class 4 felony, with every day that a violation continues constituting a separate offense.
