KINGSTON, Iowa (AP) -- Luck ran out for about a dozen pigs that escaped their flooded farm, swam through raging flood waters and scrambled atop a sandbag levee in southeastern Iowa.
Des Moines County sheriff's officials shot the pigs Tuesday, not long after they reached the levee several miles from the nearest hog farm.
Officials said they killed the pigs over worries that they would weaken the levee. Onlookers said the animals were having a difficult time trying to maneuver their way off the sandbags, and that they scurried back into the water as people approached.
"Basically you cannot have something with a hoof walk on plastic and not poke a hole in the plastic and let water into it," said LeRoy Lippert, chairman of the county emergency management commission. "Hogs, they have a tendency to root and that would not have been good either."
He said the state veterinarian and other agencies were consulted, and that 10 to 16 animals were killed.
"It happens every day. My gosh, that's what slaughterhouses do - that's how we get bacon and pork chops," Lippert said. "It's just one of the casualties of the flooding situation."
The carcasses were left at the site and treated essentially as road kill, Lippert said. "You don't get them out of the mud and over the dike when you're worried about people and people's property," he said.
Louisa County Sheriff Curt Braby said he had heard about the incident and understood why the pigs needed to be killed.
"They did not want to take a chance on losing a city due to a few hogs," he said.
Lippert noted that out of about 36,000 pigs in the Oakville area, officials estimated that only a thousand or so were left behind when the floodwaters came through.
"We trucked them as far as 200 miles away to other hog farms so that they would be taken care of," he said.
