Abstract

Objective: To determine the prevalence of Salmonella spp presence in eggs for human consumption in urban areas in Bogota. Materials and methods: 96 samples were collected from convenience stores and markets in 4 urban areas in the city. The eggshells were separated from the egg's internal content and both were processed separately using microbiological and molecular techniques to isolate and identify Salmonella spp. strains. Results: A Salmonella spp. prevalence of 9.4% (n=9) was found. Salmonella spp was isolated from the egg's internal content in 55% (n=5) of samples and 44% (n=4) from the eggshells. The Salmonella enterica serovar could not be identified. The pathogen was more frequently isolate in samples from Usaquén and Fontibón urban areas. Discussion: Studies of Salmonella spp. prevalence in eggs done in Colombia have shown it to be low (0-1.74%); However, this study determined a higher prevalence. These results suggest that inadequate handling/storage conditions could have been associated with them. Conclusion: Salmonella spp. was isolated from the egg samples from 4 different urban areas in Bogotá. These findings suggest the existence of a public health risk; therefore, there is a need to perform wider and more complete studies to determine the actual situation of Salmonella ssp. egg contamination in the country.
