Detection •Unusual sign noted by:–Producer, animal handler or processor, local vet
•Diagnostic laboratory•Processing plant
Initial Response
•Local DVM contacts State Veterinarian or AVIC
•FADD sent to investigate (within 24 hours)
•Samples submitted to Federal Lab
Risk and Response Assessment
•Response action levels determined based on disease suspected or diagnosed
•Activation of State Response Plan and/or National Response Framework
Response Actions

Animal Disease Emergency Indicators
• Increased illness, death, or abortion rates• Significant drop in production• Ulcers or blisters around the animal’s
mouth or feet• Sudden lameness • Any nervous system signs• Pox or lumpy skin conditions• Severe respiratory conditions• Any unusual or unexplained illness

FADD Investigation
• Foreign Animal Disease Diagnostician– Specially trained veterinarian
• Over 500 FADD investigations in U.S. each year• In Iowa, 25-50 each year
– Visits premise within 24 hours– Inspects animals and makes field diagnosis– Consults with State Veterinarian and AVIC on
case priority and necessary actions• Sample collection• Sample handling (priority level)• Control measures: movement restrictions, quarantine

Case Priorities
Unlikely •History and clinical signs do NOT indicate FAD
Possible •History or clinical signs not consistent
•Movement hold placed on animals by the State
Highly Likely
•Epidemiology and clinical signs fit FAD
•Quarantine initiated by the State
•Contacts traced from farm to other farms
