Costly cattle shocks

DES MOINES, Iowa — The Iowa Supreme Court affirmed the $4.75 million jury verdict against a natural gas company, whose underground pipeline’s stray voltage distressed and harmed a dairy farm’s milk cows. The stray electrical current caused many cows to get sick, extending workers’ workdays and reducing milk production, and the farm had to euthanize an unusually high number of the herd as a consequence.
