Infectious Hypodermal and Haematopoietic Necrosis Virus (IHHNV) : US shrimp farmer placed under quarantine after this deadly disease finding
Natural Shrimp Inc. which is US land-based farmer was placed under quarantine after the viral shrimp disease Infectious Hypodermal and Haematopoietic Necrosis Virus (IHHNV) was discovered at its facility in La Coste, Texas.
Presence of IHHNV is detected from two post-larvae shipments from its hatchery supplier in March and April. However, at the time of the receipt of the shipments, Natural Shrimp was notified by its supplier that the shipments were virus-free.
It was found that the growth rate is slower than normal growth rate indicating possible compromise based on the company’s quality control procedures during the course of the shrimp farming process in the company’s tanks.
The company undertook to have lots independently tested by the University of Arizona Pathology Laboratory which detected the presence of IHHNV. The facility was placed under quarantine until further notice. The quarantine notice also restricts the discharge of any culture water to state waters, and no sales of any shrimp are allowed until further notice.
