HONOLULU – Porcine epidemic diarrhea virus (PEDv) has spread to four additional farms in Waianae Valley, but no pigs show signs of the illness, the Hawaii Department of Agriculture (HDOA) reported.

The Animal Disease Control Branch of HDOA tested eight farms within a one-mile radius of the first farm affected by PEDv. HDOA issued a quarantine order stopping the movement of pigs on Oahu after PEDv was confirmed on the farm. HDOA said the affected farm appears to have recovered from the virus, and the remaining swine show no signs of illness. HDOA noted that the strain of PEDv on Oahu is a less virulent strain of the disease.


“It’s important that swine farms adhere to the quarantine order and not move pigs from the west side of Oahu without permission from the State Veterinarian ” said Scott Enright, chairperson of the Hawaii Board of Agriculture. “While there is evidence that the virus we have is a less virulent strain, keeping our livestock disease-free is of utmost importance.”

The quarantine order remains in effect, HDOA said. No swine may be moved without a permit issued by the state veterinarians.
