Abstract :

Escherichia coli and Salmonella are gram-negative bacteria and are indicators of faecal contamination in food, and the presence of each of them in processed foods indicates lack of hygiene, and Staphylococcus aureus is a gram-negative bacteria. It is positive that it has the highest level of poisoning. The aim of the present study is to investigate the contamination with Staphylococcus aureus, Escherichia coli and Salmonella in cream sweets sold in Isfahan city and the antibiotic resistance of the obtained isolates. In this study, 120 cream sweets from the supply centers of this product in different parts of Isfahan city were randomly sampled and transferred to the specialized food hygiene laboratory of Shahrekord Azad University, next to the ice flask, in order to avoid secondary contamination. The standard method was used to search for microorganisms. The collected data was used in SPSS version 26 statistical software and chi-square test was used for data analysis. The results showed that Escherichia coli and Salmonella contamination was negative in all samples, but Staphylococcus aureus was confirmed in 4 cases of cream sweets. The samples were the most sensitive to tetracycline, streptomycin and amikacin and the most resistant to penicillin and ampicillin. In this survey, it was determined that a high percentage of the cream sweets offered in Isfahan city are in compliance with the existing standards in the society in terms of contamination and health quality to some extent, but in order to improve the health of the society,
