Abstract :
Salmonella serotypes are considered as one of the most important foodborne pathogens. Eggs are a main source of the contamination caused by these pathogens and diseases in humans and the prevalence of the salmonellosis. This study was aimed to isolate Salmonella enteritidis from industrial eggs collected from different areas of Qazvin city, Iran in the year 2020.In this cross-sectional study, 200 eggs were collected randomly (including 100 industrial packaged eggs and 100 industrial tray eggs) from the retail and stores located in Qazvin city, Iran. After culturing of eggshells and egg contents according to the classic methods, suspected colonies were confirmed by PCR assay. Salmonella was detected in 10% (4/40) among the egg samples. Salmonella was isolated from 0% (0/40) and 10% (4/40) of eggshells and egg contents, respectively. Isolates from positive egg samples were characterized as S. Typhimurium.Salmonella Typhimurium is the most prevalent serotype of egg contamination in Qazvin city, Iran. It can be regarded as the risk evaluation of possible human foodborne diseases associated with the consumption of contaminated eggs.
