Commercial Hens and ducks' eggs (225 eggs) representing 45 groups   (5 eggs each as a sample) were collected from Assiut city markets and different groceries. Hens' eggs represent farm hens and native breeds. The collected samples were examined for incidence of Yersinia enterocolitica and Pseudomonas aeruginosa on egg shells and in contents                                                                                        Y. enterocolitica could not be isolated from shells ad contents of farm hens' eggs (shell and content), and the organism recovered from one sample (6.7%) of shells and 3 samples (20%) of the contents of native breeds eggs. Ducks' eggs were contaminated by the same ratio of native breeds hens' eggs. Pseudomonas aeruginosa could not recover from any of native breed eggs (shells and contents) but could be isolated from 6.7% of shells and contents of farm eggs (one sample each). Ducks' eggs proved to contain the organism in the content (2 samples) and on its shell (one sample). The public Health hazard of the isolated organisms and suggestive measures were discussed.
