Microbiological Quality and Safety Assessment of Ready-to-Eat Foods from Diverse Food Service Establishments

The escalating pace of urbanization and shifts in lifestyle have firmly established ready-to-eat foods as a fundamental component of modern dietary patterns. However, a critical aspect of RTE foods is the inherent absence of a terminal heat treatment immediately prior to consumption, which renders them exceptionally vulnerable to microbial contamination and, consequently, to the propagation of foodborne illnesses. This comprehensive study was designed to systematically evaluate the microbiological quality and safety profiles of RTE foods acquired from a spectrum of food service establishments. These included high-end five-star restaurants, established four-star restaurants, traditional local eateries known as dhaba, and ubiquitous street food vendors. A total of ["] representative RTE samples, encompassing common food items such as dal, rice, paneer masala, and paneer chilly, were subjected to rigorous microbiological analysis. Standard culture-based methodologies were employed to determine Total Plate Count, and to enumerate coliforms and Enterobacteriaceae. Additionally, specific detection methods were utilized for Escherichia coli and Salmonella spp., two key indicators of fecal contamination and potential pathogens, respectively. The results unequivocally demonstrated significantly lower microbial loads in samples originating from five-star and four-star restaurants when compared to those procured from dhaba and street food vendors. While the presence of indicator organisms was detected at varying concentrations across all investigated food service categories, it is noteworthy that neither E. coli nor Salmonella spp. were isolated from any of the analyzed samples. The consistently elevated TPC and coliform counts observed within the informal food sectors strongly suggest the prevalence of suboptimal hygienic practices and an augmented risk of post-processing contamination. These compelling findings underscore the critical necessity for the implementation of robust and strengthened food safety management systems, particularly within informal food service environments, as a paramount measure to safeguard public health.
