End of previous report period: 23 September 2005 (see Disease Information , 18 , 319, dated 30 September 2005).
End of this report period: 18 October 2005.
The affected fish were traced to a trial batch of 30 fish imported from a new source in Malaysia. The entire batch was submitted to the laboratory for PCR(1) testing for koi herpesvirus.
Although the imported fish were isolated, a follow-up investigation was conducted at the affected importer premises. All koi carp at the importer's premises were sampled for laboratory testing. The results of the PCR testing were negative. Quarantine on the movement of koi carp was imposed on the affected importer.
Based on official import data, all fish importers that imported koi carp from Malaysia after August 2005 were traced. These importers were inspected and koi carp were collected for PCR testing. All the samples from these importers tested negative.
Singapore remains free from koi herpesvirus infection.
