Abstract

A survey was conducted to determine the incidence of salmonellae in processed, ready-to-market, whole young chickens. Carcasses from 15 federally inspected chicken eviscerating plants were analyzed using a carcass washing technique for determining the presence of salmonellae. The results obtained during the 1979 incidence survey were compared to results obtained in an identical 1967 Salmonella survey.In the 1967 study, salmonellae were isolated from 171 of the 597 (28.6%) whole chicken, tetrathionate broth rinsings analysed. In the 1979 study, 222 of 601 (36.9%) of similarly analysed chicken samples were positive. Percentile positive findings from individual plants range from 7.5 to 73.7% in 1967 and from 2.5 to 87.5% in 1979.
