With the outbreak of foot-and-mouth disease in Britain and its spread in Europe, precautions have been heightened in the United States.

Charles Bishop, Alabama’s Agriculture and Industries Commissioner has quarantined 17 shipping containers that arrived in Mobile, Ala., from Britain. The containers are loaded with used tractors. Foot-and-mouth disease, a highly contagious disease, can be carried by wind, people, on clothes, shoes, tires and even by hay, water and manure.

Each of the containers will be tested for the virus before the tractors can be unloaded. If any evidence of the disease is found, the tractors will be disinfected. The disinfected tractors could then remain in the country.
