Abstract
2 Abstract: A study was conducted on 400 chicken table eggs from Kombolcha poultry multiplication and breeding farm and market at Kombolcha, Ethiopia, from October 2009 to April 2010. The objectives were to determine prevalence and public health importance of Salmonella from chicken table eggs. The samples were examined for the presence of Salmonella following standard techniques and procedures outlined by the International Organization for Standardization. From the total of 400 eggs examined for Salmonella, 46 (11.5%) were positive, from which 25 (6.3%) and 27 (6.8%) were found from egg shell and egg content, respectively. The prevalence of Salmonella in egg content of the poultry farm (10.5%) was significantly higher than the prevalence of Salmonella in egg content of open market (3.0%) (p = 0.003). The difference in prevalence observed between farm egg shell (7.0%) and market egg shell (5.5%) was not statistically significant (p = 0.535). In addition, the prevalence of Salmonella in egg shells were 14% and 0% before and after fumigation, respectively and the difference in these prevalence was statistically significant (p = 0.000). Questionnaire survey was also carried out on 130 consumers (house holds of Kombolcha). Based on the result the majority of the respondents used to store eggs in open containers, while 10% and 23% were used refrigerators and cool places, respectively. Their preference on eating raw eggs indicated that 6.2% egg consumers showed their preference for raw egg eating, while 93.8% donot prefer eating raw eggs. Six (4.6%) respondants that practiced eating raw eggs were faced a problem, while 95.4% were not facing the problem after eating raw eggs.
Salmonella is prevalent in chicken table eggs in Ethiopia, with a higher prevalence in poultry farm egg content and egg shells, and is not significantly affected by fumigation.
