Veterinarians have an active interest in the question of the importation of South American beef into this country. During the prolonged controversy which has raged over this question, they have lined up, in general, with livestock men in opposing measures which would allow South American beef to be imported into the United States in any considerable degree. In both cases, those opposed to importation do not always consider all the facts bearing on the problem; and many opposing arguments fail to distinguish between the importation of fresh beef and that of canned beef.
