The ai m of this study was to asse ss the effects of organic, organomineral and mineral fertilizers on soil contamin ation by enteric pathogens, using poultry manure as the organic fertilizer. Manure was applied in field experiments at rates of 7.0 ton. ha -1 (maize crop, 2008/2009), 8.0 ton. ha -1 (wheat crop, 2009) and 14 ton. ha -1 (maize crop, 2010/2011). Organomineral fertilizer was applied at the same rates but was comp rised of 50% manure and 50% mineral fertilizer. At 30 and 70 days after fertilization, the organic fertilizer and the upper 0-5 cm layer of the soil were tested for the presence of helminth eggs and larvae and enteropathogenic bacteria. Fecal and non-fecal coliforms ( Escherichia coli and Clostridium perfringes ) were found in the organi c fertilizer, but neither Salmonella spp. nor enteroparasites were detected. The population of ente ropathogenic bacteria in the soil was similar among the treatments for all crops at both evaluation times. The population of thermotolerant coliforms in the organic fertilizer was larger than the maximum level allowed in Brazil, but neither the organic or nor the organomineral fertilizer contaminated the soil. 2015 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303042425015 en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
