Which animal is NOT among the commonly listed FMD susceptible species in the United States?

FMD susceptibility varies by species, with cloven-hoofed animals being most at risk. In the United States, the species commonly listed as susceptible include cattle and pigs as primary domestic hosts, with deer and other wild ruminants also recognized as potential hosts. Horses, on the other hand, are much less susceptible; they rarely develop clinical disease and are not considered among the commonly listed susceptible species. This lower susceptibility means horses are not a major focus of FMD surveillance or control planning, unlike cattle, pigs, and deer, which drive most outbreak risk assessments and response efforts.
