    The level of biological risk in the air of the Landfill of the Riobamba Municipal Decentralized Autonomous Government (GADM Riobamba) was determined. The sampling was realized during 20 days, from Monday to Friday in two schedules: 10:00 and 15:00, and in the two areas of the Sanitary Landfill: hospital waste area and common waste area. The air was taken with syringes of 20 cubic centimeters and it was deposited in infusion brain- heart, 50 aspirations were made for each sample. These samples were incubated at 37 Celsius degrees during 48 hours to obtain optimal growth of the bacterias, which was planted in two different culture media, being Triptein Soya Agar and MacConkey Agar, where bacterial growth was evaluated obtaining 103 colonies morphologically different. Trough IMViC biochemical tests, pathogenic gramnegative bacteria belonging to the family Enterobacteriaceae (enterobacteria) and grampositive bacteria that cause multiple infections and diseases in humans due to contact with them. We found 12 different genera of bacteria isolated from the culture media: Shigella, Enterococcus, Enterobacter, Pantoea, Hafnia, Salmonella, Citrobacter, Staphylococcus, Escherichia, Klebsiella, Proteus and Providencia, many of them are causative of gastrointestinal diseases to humans considering the work place damage in which there is many these kind of bacteria.
