The Hawaii Department of Agriculture is halting the movement of pigs from Oahu farms after an outbreak of a serious swine disease at a Waianae farm.
The department said Thursday the porcine epidemic diarrhea virus only affects pigs and doesn't pose a risk to people or pets. It's also not a food safety concern.
About 25 percent of the Waianae farm's 150 pigs died last week. Most of those that died were piglets.
The department says it appears the remaining pigs are recovering. The farm hasn't had any deaths since the weekend.
Acting State Veterinarian Dr. Isaac Maeda issued a quarantine order saying no swine may be moved east past Nanakuli from Makaha, Waianae and Nanakuli Valley. The order also restricts the movement of swine from Oahu to neighbor islands.
