Reports New Outbreak of Necrotizing Hepatopancreatitis (NHP)


On December 18, 2014, Belize reported an outbreak of necrotizing hepatopancreatitis (NHP), a bacterial (Hepatobacter penaeid) disease, to the World Organization for Animal Health (OIE).  It was discovered during a routine health check of Penaeus vannamei from a shrimp farm in the Stann Creek area of Belize.  The source of the outbreak is unknown or inconclusive, and thus far, there have been no mortalities.  Some ponds have been quarantined and close surveillance has been recommended.  No treatments have been applied.  The disease was diagnosed in November 2014 by histopathological examination and polymerase chain reaction (PCR) at the University of Arizona’s Aquaculture Pathology Laboratory.
