ResumoDomestic fowl may constitute a major reservoir of Salmonella among animals (4). Between 1934 and 1963 more than two-thirds of the approximately 20,000 Salmonella cultures isolated from animals were from domestic fowl (5). For the past several years Salmonella heidelberg in this country has been ranked as second in incidence of various Salmonella isolated from animals (nonhuman), and one of the top four in incidence from human beings. S. heidelberg was first recovered from man by Habs, in 1933 (9), and was reported in ducks by Kauffman in 1953 (10). It was first reported in England in 1951 (6), and in Canada in 1952 (3). Several times, this serotype has surpassed S. typhimurium as the number one cause of human Salmonella infections in Canada. It is believed that the increase in human infection due to S. heidelberg was associated with the presence of the organism in foodstuffs containing egg products. The first report of S. heidelberg from animals in the United States was in 1954 (14). In 1964, 483 isolations of S. heidelberg were reported in this country from nonhuman sources. Over 90% of these came from fowl, eggs, and egg products (15). The organism has also been recovered from many domestic animals, monkeys, and turtles.
