Which combination of diseases is described as reportable and foreign animal diseases in poultry?

• A. Newcastle disease and highly pathogenic avian influenza
• B. Marek's disease and Infectious laryngotracheitis
• C. Fowl cholera and exotic Newcastle disease
• D. Infectious laryngotracheitis and Marek's disease

Answer: (A)

The key idea is that some poultry diseases are designated as both reportable to authorities and as foreign animal diseases because they can rapidly spread and cause major economic and animal-health impacts. Newcastle disease fits this role: it’s a highly contagious viral disease of birds that is notifiable to state and national authorities, and in many regulatory frameworks it is treated as a foreign animal disease, triggering strict reporting, quarantine, and eradication actions if detected. Highly pathogenic avian influenza likewise is a reportable disease and is classified as a foreign animal disease due to its potential for rapid spread across borders and severe flock mortality, plus significant trade implications.

The other options pair diseases that are not routinely considered foreign animal diseases, or are not both reportable and FADs in poultry. Therefore, the combination of Newcastle disease and highly pathogenic avian influenza is the correct pairing.
