THE finding of Salmonella types in Canadian dried egg powder (Gibbons and Moore, 1944) raised the question of their mode of entrance. According to Jungherr and Clancy (1939), Mallman et al. (1942), Darby and Stafseth (1942), Edwards and Bruner (1943) and Hinshaw et al. (1944), Salmonellae are widely distributed in fowl in the United States, and they are probably more common in Canada than is realized. The organisms may be transmitted from infected ovaries to the yolk, or from infected fecal matter to the shell or the egg contents. Although definite reference to the first mode of transfer has not been found in chickens (Bunyea, 1942), (except, of course, S. pullorum), Hinshaw and his co-workers (1942, 1943) have shown that this is possible in turkeys. The transmission through fecal matter is obvious and it has been shown by Schalm (1937) that the organisms can penetrate the shell of chicken eggs, . . .
