What is probably the number one agricultural threat to the US?

• A. Avian influenza
• B. Foot and mouth disease
• C. Bovine spongiform encephalopathy
• D. Swine fever

Answer: (B)

Foot-and-mouth disease stands out because it is highly contagious across many key livestock species (cattle, pigs, sheep, goats, and more) and can spread rapidly through direct contact, aerosols, and contaminated equipment. If it were introduced into the United States, the result would be immediate and extensive movement controls, quarantines, and mass culling, leading to enormous economic losses across the beef, dairy, pork, and leather sectors and severe disruptions to export markets. The scale of disruption goes beyond a single species or sector, which is why the overall impact on agriculture would be so much greater than other diseases. Avian influenza primarily threatens poultry and wild birds, and while serious, it does not pose the same multi-species, cross-sector disruption or trade-damaging ripple effects as foot-and-mouth disease. Bovine spongiform encephalopathy is serious but has been controlled through strict surveillance and feed regulations and does not trigger the same rapid, wide-reaching outbreak dynamics. Swine fever would be devastating if it entered the country, but it is not currently present in the United States, so its immediate national threat level is different from that of foot-and-mouth disease.
