Abstract

Escherichia coli considered a gram-negative bacterium is part of the intestinal microbiota of humans and animals, it is considered that some of its pathogenic strains can cause serious intestinal infections and chronic complications such as hemolytic uremic syndrome especially in older adults and children. Objective: The work aims to identify the presence of Escherichia coli in frozen chicken samples, these microbiological research studies included the good preparation of the samples according to the regulations studied, cultures in specific media such as EC Agar, EC Broth, biochemical tests for the identification of Escherichia coli through the NTE INEN 1529-8 standard and other national regulations. Methods: according to the method performed, presumptive tests (NMP) were used such as confirmatory tests such as sowing for microorganism identification. Conclusion: The microbiological study confirmed the absence of Escherichia coli, demonstrating effective hygienic handling throughout the entire process. Comparison with current regulations determined that the product was handled appropriately, ensuring its safety and reducing the risk of foodborne illness. Results: Based on the results obtained from the microbiological tests performed on the frozen chicken samples, the absence of Escherichia coli was determined, indicating that the product was safely handled and preserved for consumers.
