Project Summary Abstract The Louisiana Animal Disease Diagnostic Laboratory (LADDL) is an accredited laboratory with the American Association of Veterinary Laboratory Diagnosticians (AAVLD). LADDL is committed to maintaining the highest accreditation standards, improving existing diagnostic services, and developing new tests to meet the demands of its industry stakeholders and regulatory agencies. LADDL works through multiple state and national cooperative agreements to perform diagnostic surveillance for endemic, targeted, and foreign animal disease to enhance the biosecurity of the food and agricultural industries throughout the nation. LADDL is a member of the Veterinary Laboratory Investigation and Response Network (Vet-LIRN) and will work through this cooperative agreement to strengthen the network by participating in Vet-LIRN sample analyses, providing analytical data to support potential regulatory use, and participating in additional projects as determined by the Vet-LIRN Program Office.
