A total of 50 random samples of liver and gizzard from freshly slaughtered chicken carcasses
(slaughtered, plucked and eviscerated) (25 of each) were collected from local commercial retail
shops in Menofia government. It is evident from the results that the mean value of aerobic plate
count (APC) (cuf/g) of examined samples of chicken giblets was 4.86×10⁴±0.92×10⁴ in liver and
7.73×10⁴±1.68×10⁵ in gizzard and the incidence of E.coli in the examined chicken liver and gizzard
were 20% and 28% , respectively. Also, the serologically identified E.coli isolates in the examined
samples were O₂₆ : H₁₁ (4%) , O₅₅: H₇ (4%), O₉₁: H₂₁ (4% )and O₁₂₈: H₂(8%) in liver and O₂₆ :
H₁₁ (8%) , O₇₈(4%), O₁₁₁: H₂ (4% ), O₁₁₉: H₆(4%), O₁₂₄(4% )and O₁₂₆: H₂₁(4%) in gizzard.
Salmonella was isolated from 24% and 36% of liver and gizzard and incidence of the isolated
serotypes were S.Entritidis (4% and 12%), S.Infantis (4% and 4%), S.Kentucky (4% and 4%),
S.Typhimurium (8% and 8%), S.Labadi 4% & S.Virchow 4% in gizzard and S.Larochelle 4% in
liver only.
