Biosecurity That Works
March 1, 2003
For Immediate Release
Syndel Laboratories Ltd. and biosecurity partners Vetoquinol and Antec
International are pleased to announce that an extensive disinfectant study has
shown Virkon and Hyperox to be extremely effective in controlling Infectious
Salmon Anemia Virus (ISAV). The
study was conducted at AVC Inc. and confirms results of an earlier RPC (Research
Productivity Council) study done for the New Brunswick Salmon Growers
Association. Dr. Jim Brackett,
General Manager of Syndel Labs states “ This study confirms that Virkon and
Hyperox are the best disinfectant products available for your biosecurity
program.”
A titre log reduction of greater than 3.0 – 4.0 (10-3.0 – 10-4.0
change in cell counts) is generally accepted as indicating an effective viral
disinfectant. Under all test
conditions both Virkon and Hyperox showed titre log reductions of 5.50 – 5.75. These conditions include both
clean viral samples and those containing a heavy organic load. Virkon is used at 1:100 and 1:200
dilution and Hyperox is used at 1:128 and 1:256 dilution.
ISAV joins a growing list of pathogens that are rapidly killed by Virkon and
Hyperox. These include important
aquatic pathogens including IHNV, Aeromonas and other bacteria, viruses and
fungi.
For general disinfection, Virkon is the product of choice. However, for egg disinfection, Ovadine
is still the best. In the RPC
study, Ovadine was effective at controlling ISAV on clean samples (like fish
eggs). Paul Casey Sales and
Marketing Manager of Syndel Labs states “Ovadine has been used worldwide for
more than 20 years in disinfecting fish eggs exposed to many commercially
important diseases with continuing good results.
Furthermore Ovadine is uniquely balanced for use on fish eggs”.
Syndel advocates and encourages all aquaculturists to use proven disinfectants,
such as Virkon, Hyperox and Ovadine, as part of their biosecurity program.
