Salmonella Organisms on and in Chicken Eggs

THE purpose of this investigation was to obtain information concerning the part played by shell eggs in contributing to the contamination of egg powder with organisms of the genus Salmonella. The common occurrence of Salmonella types other than S. pullorum and S. gallinarum in the meats of chicken eggs has not been conclusively established, although Watt (1945) reported the isolation of S. Montevideo. We are not aware that other types have been isolated from meats of naturally infected chicken eggs in this country. On the other hand, current literature records well over 50 types isolated from spray dried whole egg powder manufactured in the United States (Gibbons and Moore, 1944; Schneider, 1946; Haines, Elliot and Tomlinson, 1947; Solowey et al., 1947). Current literature also reveals that nine of the types found in egg powder, in addition to S. pullorum, have been isolated from shells of chicken eggs within the last three . . .
