KAHUKU SHRIMP FARM QUARANTINED

The state Agriculture Department issued a quarantine order Friday prohibiting Ming Dynasty Fish and Shrimp Co. from moving any shrimp onto or off its farm without a permit due to an outbreak of Taura syndrome virus, a potentially serious shrimp disease that is not harmful to humans even if consumed.

Samples collected from the farm March 16 by an aquatic veterinarian detected the virus in one of the farm's two aboveground concrete ponds. The source of the infection has not been determined.

Ming Dynasty is the only farm in the Kahuku area that participates in the Aquaculture Development Program's shrimp surveillance and certification program, which certifies farms as "specific pathogen free."
