Abstract: The consumption of ground meat is a deeply rooted gastronomic tradition in Brazilian food culture, primarily due to its culinary versatility and affordability. This has led to a gradual increase in its consumption in recent years. Contamination of ground meat becomes common due to factors such as excessive handling and the use of inadequately sanitized equipment and utensils. This renders it susceptible to becoming a problematic product, often associated with outbreaks of foodborne illnesses. This study was conducted with the aim of assessing the microbiological quality of ground beef. Twenty samples of ground beef exposed for consumption were collected from different franchise supermarkets in the city of Teresina, Piauí, Brazil. According to Brazilian legislation that standardizes microbiological limits in food, concerning mesophilic aerobic bacteria, 7 samples (35%) were deemed unfit for consumption due to high bacterial counts, reaching 106 CFU/g; 10 samples (50%) were classified as having intermediate quality, with counts between 105 and 106 CFU/g, and only 3 samples (15%) were considered suitable for consumption, with counts equal to or below 105 CFU/g. Regarding thermotolerant coliforms, 7 samples (35%) presented counts exceeding 102 MPN/g and were classified as unsuitable for consumption; 4 samples (20%) had values between 10 and 102 MPN/g, falling into the intermediate quality category; 9 samples (45%) were deemed acceptable for consumption, with counts equal to or below 10 MPN/g. Eight samples (40%) showed the presence of the Escherichia coli bacteria. No samples were condemned for consumption due to the presence of Salmonella spp. In light of the results, it can be concluded that this study underscores the importance of implementing and reinforcing hygiene and food safety practices throughout all stages of the production and distribution chain of ground meat. This approach ensures that the marketed foods adhere to established microbiological standards, thereby reducing the risks associated with foodborne disease outbreaks and safeguarding public health.
