Considering the growing importance of fermented dairy products in the domestic market and the scarcity of data in the Federal District (DF), it was evaluated the quality and microbiological safety of these products in the DF and its adaptation to current standards. The study was conducted in five dairy being collected 105 samples of fermented dairy products corresponding to 21 lots (n = 5 per lot), with 65 samples of yogurt, 20 of curd and 20 of fermented dairy drink. All samples were submitted to a count of aerobic mesophilic, psychrotrophic, coliforms at 35 ° C, Escherichia coli, Staphylococcus coagulase positive, Salmonella spp., molds, yeasts and viable lactic acid bacteria (BAL). The total lots analyzed, 62% were considered acceptable under the Regulatory Instructions n ° 46/2007 and n ° 16/2005. In order of quality, fermented dairy drink was the one with lots more apt to consumption (75%) followed by yoghurt (61.5%) and, lastly, curd (50%). For samples units, the results showed that: 17% of yoghurt samples, 15% of curd and 20% of fermented dairy drink showed scores above the allowed CT; 11% of yoghurt samples and 30% of fermented dairy drink showed BAL counts below specific minimum limits; and 61% samples of yogurt and curd were 30% of curd was with yeasts and molds counts above permitted. No samples showed the development of E. coli or Salmonella spp. Despite the absence of microbiological hazards in the samples analyzed, the study indicates problems in the production of these products in the DF that may be related to deficiencies in hygienic of the processes, most rigor in the quality controls of dairy and oversight of industries is needed. Considerando a crescente importância dos derivados lácteos fermentados no mercado nacional e a escassez de dados no Distrito Federal (DF), foi avaliada a qualidade e a segurança microbiológica destes produtos no DF e sua adequação aos padrões vigentes. O estudo foi desenvolvido em cinco laticínios sendo coletadas 105 amostras de derivados lácteos fermentados correspondentes a 21 lotes (n=5 por lote), com 65 amostras de iogurte, 20 de coalhada e 20 de bebida láctea fermentada. Todas as amostras foram submetidas à contagem de aeróbios mesófilos, psicrotróficos, coliformes a 35°C, Escherichia coli, Staphylococcus coagulase positivo, Salmonella spp., bolores, leveduras e bactérias ácido-láticas viáveis (BAL). Do total de lotes analisados, 62% foram considerados aceitáveis segundo as Instruções Normativas n° 46/2007 e n° 16/2005. Em ordem de qualidade, a bebida láctea fermentada foi a que apresentou mais lotes aptos ao consumo (75%), seguido do iogurte (61,5%) e, por último, da coalhada (50%). Por unidades amostrais, os resultados demonstraram que: 17% amostras de iogurtes, 15% de coalhada e 20% de bebida láctea fermentada apresentaram contagens de CT acima do permitido; 11% amostras de iogurtes e 30% de bebida láctea fermentada apresentaram contagens de BAL abaixo dos limites mínimos específicos; e 61% amostras de iogurtes e 30% de coalhada estavam com contagens de bolores e leveduras acima do permitido. Nenhuma amostra apresentou desenvolvimento de E. coli ou de Salmonella spp. Apesar da ausência de perigos microbiológicos nas amostras analisadas, o estudo realizado indica problemas na produção desses derivados no DF que podem estar relacionadas a deficiências na higiene dos processos, sendo necessário maior rigor nos controles de qualidade dos laticínios e na fiscalização das indústrias
