Abstract

The fact that multidrug-resistant bacteria are common on eggshells sold in wet markets is very vulnerable for public health, especially since eggs are often handled poorly. As part of this study, chicken eggshells from different wet markets in Taif, Makkah area, Saudi Arabia, were collected and tested for bacterial pollution. Overall, a total of 150 eggs were randomly selected and examined for both external and internal microbial contamination. The VITEK 2 antimicrobial sensitivity showed significant multidrug resistance, especially in the Salmonella enterica strain. 16S r-RNA was used to identify five types of bacteria: Escherichia hermannii, Escherichia coli, Staphylococcus aureus, Staphylococcus xylosus, and a new strain of S. enterica (A10). Finding S. enterica A10 on eggshells in this area is the first narrative of its kind, showing that eggshells are an underrated way for antibiotic-resistant bacteria to spread. More protection, limits on drug use in chicken, and better cleanliness in local markets are all needed because of these results.
