Import Risk Analysis of the Decapod Iridescent Virus 1 (DIV1) Applied in South Korea: Qualitative Risk Review and Institutional Improvement Plans
Table 10
DIV1 risk management plans and sanitary conditions for imported aquatic products.
(a) DIV1 management plans
Plans
Target use
Details
Note
Removal of head and shell
Nonhuman consumption (crustaceans and polychaetes for feed and bait)
(i) Systemic infection occurs due to hemocyte infection, but major targe tissues are removed
(i) Partial loss of function as feed or bait
Quarantine
(i) Designation of crustaceans and polychaetes for feed and bait as the aquatic organisms designated for quarantine purposes
(i) Redclaw crayfish and red swamp crayfish have no risk of exposure as these are not used for feed or bait (ii) Quarantine of frozen/refrigerated crayfish should be performed if crayfish imports change, or new exposure routes are discovered (iii) In the case of two types of crabs, if evidence of completely susceptible ins confirmed, they should be designated as quarantine targets
(b) DIV1 sanitary conditions
Pre-export conditions
Nonhuman consumption (crustaceans and polychaetes for feed and bait)
(i) Attaching the quarantine certificate issued by the competent authority of the exporting country after a close inspection before export
(i) Proving negative after DIV1 close-up and there are no gross pathology lesions
or
(i) Attaching a disease-free certificate issued by the competent authority of the exporting country certifying that the country is a clean country or clean area
(i) Issuance of an export quarantine certificate certifying that the country has been confirmed as a disease-free country through a surveillance method per WOAH hygiene regulations
and
Conditions for postarrival import quarantine
Nonhuman consumption (crustaceans and polychaetes for feed and bait)
(i) Implementation of import quarantine and exemption from quarantine for certain product types
(i) Implementation of import quarantine on completely susceptible species (however, exemption from quarantine for products types that fall under the removal of head and shells)
or
(i) Mooring and quarantine (quarantined during the incubation period of the disease)
(i) Examination of gross pathology lesions during the 2-week acclimatization period and implementation of close inspection when gross pathology lesions appear
(c) Alternations for DIV1 risk management plans
Reduce the tariff rate
Nonhuman consumption (crustaceans and polychaetes for feed and bait)
(i) Reduce the current tariff rate of 10%–20%–0%–5%
(i) The cost of quarantine inspection can be offset by lower tariff rates, preventing objections from related industries
