Question

which disease is a biosecurity risk because it can spread up to 50 miles airborne?
anthrax
salmonella
fmd
shigella

Explanation:

Anthrax is a biosecurity risk because it can spread up to 50 miles airborne. Anthrax spores can be dispersed through the air, making it a significant concern in terms of bioterrorism and biosecurity. Shigella and Salmonella are typically transmitted through contaminated food or water (not primarily airborne over long distances like 50 miles). FMD (Foot - and - Mouth Disease) is mainly transmitted through direct contact between animals or via contaminated objects (not known for airborne spread up to 50 miles).

Answer:

Anthrax
