State v. Morison
Summary:
Cattle owners sued the state and its agricultural commission for negligently performing the duty to use proper steps to prevent the spread of a contagious disease after they bought dairy cows at a sale that subsequently infected their herd. The owners were forced to sell their herd of dairy cows. The Supreme Court held that the owners could recover the difference between fair market value of their herd before and after it contracted the disease, loss of profits due to diminished milk production from cows before sale, value of silage or feed that had been contaminated, and reasonable costs of disinfecting the farm, but not for loss of profits for the dairy operation after they sold the cows, or loss of progeny.
