Abstract

Eggs, considered as a staple food in households, are characterized with having semi-permeable shell membrane where certain strains of bacteria may be found. The stated case poses potential health risk to possible consumers as the presence of these microorganisms may give rise to a range of foodborne diseases that concern the well-being of the public. This study aimed to detect the presence of presumptive Enterococcus faecalis and presumptive Salmonella enteritidis on the shells of the eggs procured from three public markets with the highest number of market goers at Dasmariñas City, Cavite namely Marketmall Public Market, Central Market, and Luzviminda II Public Market. The researchers intend to determine whether the eggs purchased from the three markets are safe enough to be ingested by the consumers as well as guarantee the proper sanitation conducted by poultry farms and egg vendors on their products. The experimentation was thoroughly conducted at Angelo King Research Center building in De La Salle Medical and Health Sciences Institute. The acquired samples have undergone various laboratory processes including swabbing as well as culturing and isolation of bacteria through streak plate method. Analysis of the results was done after which showed a low occurrence of presumptive Enterococcus faecalis and zero prevalence of presumptive Salmonella enteritidis on the obtained eggshells. Following these findings, the research suggests that bacterial confirmation may be done to further ensure the presence of the identified microorganisms.
