Biological Hazard in USA on Friday, 25 April, 2014 at 15:24 (03:24 PM) UTC.
Tens of thousands of Asian carp are believed to have died in a 24-hour period in the Cumberland River below Lake Barkley, and state officials are investigating. The Kentucky Department of Fish and Wildlife Resources says specimens of the invasive silver carp will be taken to Kentucky State University for disease testing.
Fish and Wildlife’s western fisheries district biologist, Paul Rister, says Kentucky Lake and Lake Barkley don’t appear to be affected by the die-off discovered Wednesday. Evidence of the fish kill was documented to the confluence with the Ohio River. Rister says the source could be viral or bacterial. He says if water quality was the cause, other species would be affected.
The agency says the fish have spread throughout much of the Mississippi River basin after escaping from fish farms in the 1970s.
Biohazard name: Mass. Die-off (Asian carp)
Biohazard level: 2/4 Medium
Biohazard desc.: Bacteria and viruses that cause only mild disease to humans, or are difficult to contract via aerosol in a lab setting, such as hepatitis A, B, and C, influenza A, Lyme disease, salmonella, mumps, measles, scrapie, dengue fever, and HIV. “Routine diagnostic work with clinical specimens can be done safely at Biosafety Level 2, using Biosafety Level 2 practices and procedures.
Research work (including co-cultivation, virus replication studies, or manipulations involving concentrated virus) can be done in a BSL-2 (P2) facility, using BSL-3 practices and procedures. Virus production activities, including virus concentrations, require a BSL-3 (P3) facility and use of BSL-3 practices and procedures”, see Recommended Biosafety Levels for Infectious Agents.
