--- The microbiological quality of food is essential to ensure the availability of an innocuous and high quality product to the consumer. Vended foods with high pollution; as a result of various factors such as improper handling at various stages, converted to dairy like cheese, meat products such as ground beef and creeping fruits like strawberries; in highrisk foods associated with outbreaks of diarrhea. Among the pathogens that may be carried by foods include Enterobacteriaceae of the gender Escherichia, Salmonella, Shigella among the most frequent. El present research had as objective to determine the frequency of Enterobacteriaceae in fresh cheese, ground beef and strawberry in the wholesale market La Parada in the period March - June 2012, determine the percentage of coliforms and no coliforms Enterobacteriaceae; and determine in the analyzed samples the food in that prevail Escherichia coli. Has been colleted a total of 50 samples, 17 of fresh cheese, 17 of ground beef and 16 of strawberry (Fragaria vesca) from La Parada. The samples were analyzed according to the methodology of the ICMSF (International Commission on Microbiological Specifications for Foods) and biochemistry tests. In the study has been found that total of analyzed samples 66% have Escherichia coli, 12% Enterobacter, 4% Shigella and 18% others Enterobacteriaceae. In adittion, of the total of Enterobacteriaceae found in the samples 78% are coliforms and 22% no coliforms. Regarding the prevalence of Escherichia coli in the analyzed samples, has been found 82% de Escherichia coli in ground beef.
