Detection of the Red Sea Bream Iridovirus (RSIVD) and Quality of Frozen Mackerel (Scomber japonicus) Imported Through the Port of Tanjung Mas Semarang

Abstract

The imported frozen fish and fishery products can be a carrier of transboundary fish pathogen that subsequently may cause serious threat to the natural fish inhabitants, sustainability of aquaculture, human health and fisheries business in general. One of the transboundary fish diseases is Red Sea Bream Iridovirus Disease (RSIVD) caused by RSIV. The virus has been reported occurred in many countries that has active trading of fish and fisheries product with Indonesia such as Japan Cina, Taipei, Hong Kong, Korea, Malaysia, Philippines, Singapore and Thailand. In the last four years, whole frozen mackerel (Scomber japonicus) is the most imported fisheries commodity through Tanjung Emas Port. The objective of this study were to detect the presence of RSIV using PCR method according to OIE and quality as food fish for human consumption by examining for Organoleptic test, TPC, E. coli, histamine test, and the presence of parasites Anisakis sp. according to Indonesian national standard (SNI). Fish samples (25 fishes/entries) were obtained by random sampling of 10 importing entries. Results showed that there was no RSIV detected. The results of quality testing include organoleptic test, TPC, E. coli, histamine meet the SNI standard of raw fish quality. Anisakis sp. was found with the prevalence between 12 - 100%. There is one import entry that does not meet the requirements of the minimum value of organoleptic and TPC values so that it does not meet the quality standards of raw materials.
