<p>Foodborne diseases have a great impact on public health, with <em>Salmonella </em>spp. one of the pathogenic microorganisms that most produces gastrointestinal disorders in humans. The objective of the present work was: To determine the presence of Salmonella spp. in raw chicken marketed in the southeast zone of the city of Tunja. 91 samples of chicken legs were randomly taken to which physicochemical analysis (pH, Aw water activity, humidity) was performed to determine the presence of <em>salmonella</em>. Tecra visual immunoassay ELISA test (VIA 96TM) was used. The chi-square statistical test with contingency tables was applied to evaluate the relationship between the variables: temperature, pH and Aw and the presence of <em>Salmonella</em> spp. in the samples analyzed. Of the 91 samples analyzed, n = 57 were positive for <em>Salmonella</em> spp. corresponding to 62.6 %.</p>
