PREVENTION.—When any of the above mentioned symptoms are noticed, non-affected animals should immediately be removed to non-affected quarters. This disease is not communicated through the atmosphere but by the animal coming into direct contact with the infection or virus; hence it is not necessary to move unaffected animals any great distance but merely to clean, sanitary quarters which have not been subjected to any possible infection from the diseased animals. It must be borne in mind that the attendant or helper cannot be too careful in the matter of his own actions and dress as the infection is easily carried through clothes, fecal matter, etc., adhering to shoes or any matter or articles, such as buckets, brushes, rub-rags, blankets, etc. The existence of this disease should at once be reported to the State Veterinarian of your State or to the United States Bureau of Animal Industry at Washington, D. C. TREATMENT.—I cannot recommend any treatment as being satisfactory or a cure, for although under some treatments the animal appears to make a good recovery, in the majority of cases the feet are disfigured and crippled, the udder permanently injured with growths, animal unfit for milking purposes, and the mouth, tongue and teeth left impaired; the mouth and tongue strictured from wounds and the teeth loosened from the gums. Furthermore, should an animal make apparent recovery, it is not immune from a recurrence of the disease. In treating the disease, there is not only danger of spreading the disease to other animals, but to man. The flesh or milk from animals apparently cured should never be used unless first examined by a qualified meat inspector. Without question, all animals showing severe symptoms as above described should be at once slaughtered and buried six feet or deeper, covering carcass with Quicklime and then promptly filling grave, according to the Government regulations, which should be followed explicitly. Be careful to disinfect scene of slaughter, as bloodstains, etc. The United States Bureau of Animal Industry regulates the disinfectants to be used and the strength thereof, and as these are subject to change from time to time, I must refer you in this matter to the proper Government authorities.
