What is the most common means of entry into an FMD-free country?

• A. Airborne via wind
• B. Swill (uncooked garbage)
• C. Import of live animals
• D. Contaminated water supply

Answer: (B)

Swill, or uncooked garbage containing meat products, is the most common way FMD enters an FMD-free country. The virus can survive in meat and other animal products if they aren’t properly cooked, and when such material is fed to pigs, it can seed infection in a farm and then spread. This route bypasses formal import checks and can introduce virus long before authorities detect an outbreak, which is why it has historically been a major risk factor. Airborne spread can occur but requires specific conditions and close proximity, making it less likely as the primary border-entry route. While importing live animals is also a risk, strong quarantine and testing protocols are designed to minimize that pathway, and contaminated water is not a common long-distance vehicle for FMD.
