Includes references.

This work was undertaken to determine the degree of contamination by psychrotrophic pathogens (Listeria and Yersinia species) among slaughtered poultry ( chicken, duck, geese, squabs) and rabbit. A total of 120 slaughtered poultry carcasses with their gizzard and liver and 30 rabbit carcasses with their liver only were randomly collected from selected retail poultry shops in Giza city. L.monocytogenes was obtained by 3.3% from chicken carcass, 6.6% in rabbit carcass and 3.3% from rabbitfs liver. L.innocua and L. grayi were isolated with different percentages. Y. enterocolitica was isolated with percentages 33.3%, 50% and 53.3% in chicken carcass, gizzard and liver respectively. In ducks, it was 43.3, 53.3% and 53.3% for whole carcass, gizzard and liver respectively; while in geese it was 23.3%, 33.3% and 43.3%. In squabs it was 6.6% for carcass only but it failed to be detected in rabbit. Y. intermedia and Y. frederiksenii could be isolated. The health risks of the isolated Listeria and Yersinia species were discussed.
