A foreign animal disease could enter the United States on/in:

• A. Air freight containers
• B. Ships
• C. People
• D. All of the above

Answer: (D)

Foreign animal diseases can enter the United States through multiple routes that involve contact with animals, animal products, or contaminated materials. Air freight containers can carry contaminated goods, equipment, or even pests that harbor pathogens. Ships can bring in infected animals or contaminated cargo, or pests traveling in cargo or ballast water. People can inadvertently transport pathogens on clothing, footwear, or gear, or even carry infected animals or animal products. Because any of these pathways could introduce disease, the safest answer is that all of the above are possible entry routes.
