Aquatic Animal Health Status Reviews

Last Modified: December 11, 2024

APHIS Veterinary Services conducts annual reviews to determine the health status of select aquatic animal pathogens of concern for the United States or regions within the United States.

List of Aquatic Animal Health Status Reviews

These reviews are based on the World Organisation for Animal Health (WOAH) criteria as specified in Chapter 1.4. Aquatic Animal Disease Surveillance of the WOAH Aquatic Code. Data to support these reviews include annually aggregated and anonymous pathogen testing data collected using a collaborative process with private and public partners, as well as review of regulations, competencies, and oversight that together ensure the maintenance of basic biosecurity conditions.
