Abstract
During 1945, Salmonella organisms (other than S. pullorum) were isolated from 112 of 400 samples (28.0%) of Canadian dried egg powder. Fourteen types were found: S. oranienburg, S. typhimurium, S. thompson, S. montevideo, S. newington, S. bareilly, S. manhattan, S. potsdam, S. anatum, S. newport, S. Paratyphi B (tartrate positive), S. bredeney, S. tennessee, and S. selandia (listed in order of prevalence). S. pullorum was isolated from 17 samples. In the majority of samples the most probable number of organisms was less than one per gram. No Salmonella organisms were found on the shells of 12,276 commercial eggs; Salmonella were isolated from the shells of eight of 24 eggs and later from the meats of two of 144 eggs from infected flocks.
