Indicator 4.2.1.5

by Contact on 8 October 2026

Requirement

The UoC shall only stock batches of crustaceans, including nauplii, larvae, post-larvae and broodstock, that have been tested prior to stocking and are free from diseases of regional concern, and met importation guidelines when applicable.

How Do I Interpret This Requirement?

  • Testing should be relevant to:

    • The species.

    • The production system.

    • The scale of production.

    • The local regulations.

      • For example:

    • Early mortality syndrome (EMS), which is also known as acute hepatopancreatic necrosis disease (AHPND).

    • Enterocytozoon hepatopenaei (EHP).

    • White spot syndrome (WSS).

  • Testing might consist of:

    • Clinical examination of the crustaceans.

    • Laboratory tests:

      • Bacteriology.

      • Molecular biology (e.g. PCR).

      • Histopathology.

      • Virology (e.g. cell culture).

  • The designated veterinarian or aquatic animal health professional should determine:

    • The diseases to include in the testing, based on local regulations, scientific literature and/or publicly available information (see interpretation for Indicator 4.2.1.8).

    • The sample size, based on local regulations and/or technical judgement.

    • Compulsory governmental testing programme results are acceptable for demonstrating conformance with this requirement.

Evidence of Implementation

  • List of relevant diseases for the species in the country (see interpretation for Indicator 4.2.1.8).

  • Testing results written report or document that includes as a minimum:

    • The batch of crustaceans being tested.

    • The date of the test.

    • The pathogen tested.

    • The results of the test.

  • Records:

    • Purchase.

    • Transportation.

    • Delivery.

    • Stocking.

Auditors Should Confirm

  • Every batch of crustaceans has been tested by cross-checking the list of relevant diseases for the species in the country with the testing result’s written report or document and records.
