Global prevalence of Staphylococcus aureus in food products and its relationship with the occurrence and development of diabetes mellitus

The worldwide distribution of Staphylococcus aureus across food types is an important food safety concern. This study aimed to estimate the prevalence of S. aureus in food products and its relationship with the occurrence and development of diabetes mellitus. A total of 55 articles were included. The pooled prevalence of S. aureus was 30.2%. The highest prevalence of S. aureus was observed in cereals, followed by meat and bean products, and the lowest in confectionery, egg products, and vegetables. The prevalence in dairy and seafood products was similar. Combinations of culture and molecular methods have been used for S. aureus detection. Furthermore, the prevalence of S. aureus in developed countries (Europe and North America) was higher than that in developing countries (Asia and Africa). In addition, the prevalence was higher in the provinces of Xinjiang and Shaanxi than that in Sichuan and Shandong in China, which may be due to the difference in climate and dietary habits. The results revealed that food type, bacterial detection methods, and location can influence the prevalence of S. aureus contamination. Resistance rates to preferred antibiotics against S. aureus were the highest for cephradine, polymyxin B, and penicillin at 82.9%, 82.0%, and 81.3%, respectively. In addition, 17 studies were system reviewed that the S. aureus infections are closely associated with the development of diabetes, and the treatment of probiotic, prebiotic, FMT, and bacteriophage can prevent and control S. aureus infections. This review emphasizes the high prevalence of S. aureus contamination in food, suggesting a potential diabetic infection risk and importance of observing principles of food safety and hygiene to reduce S. aureus.
