The present investigation was carried out in the department of Huánuco with the objective to determine the fre- quency and risk factors associated with contamination by Salmonella and Staphylococcus aureus in the main meats sold in the markets of Huánuco. 120 samples of meat were collected and sold in the main markets of Huánuco: M. modelo, M. antiguo and M. de Paucarbamba, laboratory analysis of the samples was carried out in the Microbiology laboratory of the Faculty of Veterinary Medicine and Zootechnics of the UNHEVAL. The frequency of Salmonella in the main markets of Huánuco was 5% and the samples free of Salmonella was 95%. (P = 0.005). The samples contaminated with Salmonella in the main meat of Huánuco were of (6/120), that is to say 6 samples of the 120 samples analyzed were contaminated with salmonella and therefore they are considered unfit for its consumption. Similarly, Salmonella free samples were (114/120), ie 114 samples of the 120 samples analyzed were free of salmo- nella and therefore were considered suitable for consumption. With respect to the frequency of Staphylococcus, in 67 samples values lower than 120 colony forming units (CFU) were found, considering them unfit for consumption (55%) and in 53 samples values higher than 100 colony forming units were found (CFU), consequently, they are considered unfit for consumption. When establishing the relationship between the presence of salmonella and the hygienic conditions of meat vending in the three markets, of the 114 samples suitable for consumption, 41 samples correspond to meat sellers who do not have good hygiene conditions representing the 34.2%. With regard to the frequency of Staphylococcus, values greater than 100 colony-forming units (CFU) were found in 55% of the sam- ples. Consequently, they are considered unfit for human consumption.
