Salmonellosis is one of the most common and widely distributed food-borne diseases. It constitutes a major public health burden and represents a significant cost in many countries. The aim of this study is to determine the prevalence Salmonella spp. in poultry eggs from different retail markets of Savar area, Bangladesh. A total of 103 poultry eggs were examined to investigate the prevalence of Salmonella spp. The isolated samples were presumptively identified by established conventional cultural method and biochemical tests for Salmonella spp. detection. The average prevalence of Salmonella was found to be 86% in poultry eggs. Among these, 83% from outer shell of eggs and 3% (3 isolates) from egg contents were identified. In this study, we also observed that the prevalence of Salmonella spp. that was higher in spring (91%) season than in winter (82%) season. Prevalence of Salmonella spp. was significantly higher in egg shell compared to egg contents (p<0.01). The present study represents that poultry eggs are potential reservoir of Salmonella spp. Human illnesses may be associated with pathogenic Salmonella spp. during consumption of contaminated poultry eggs. Intervention strategies are hence important to control Salmonella infection from farm to fork.
