Abstract
In the present study Salmonella spp. was surveyed in four flocks of meat-type quails reared in a farm that also had processing plant on site, located in the region of Bastos, state of São Paulo, Brazil. Meconium samples of one-day-old quail chicks were collected from transport cardboard boxes. Cecal content was collected on days 7, 14, 21, 28 and 35 of rearing. At 36 days of age, birds were slaughtered in the farm's processing plant, where two samples of water from the scalding and the chilling tanks and four carcasses per flock were collected. All samples were examined for Salmonella spp. using traditional bacteriological methods. Salmonella spp. was present in meconium samples of three flocks and in cecal feces of the four flocks. This bacterium was also isolated in the chiller water and in the carcasses of three of the evaluated flocks and in the scalding water of one flock. In this study, S. enterica subspecies enterica 4, 5, 12; S. Corvalis; S. Give; S. Lexington; S. Minnesota; S. Schwarzengrund; S. Rissen and S. Typhimurium were the eight serovars identified.

Summary
Quail farming was introduced in Brazil in the early 1960s for egg production purposes. As well as the industrial production of other domestic poultry, quail meat production has benefitted from genetic improvement, better feed efficiency and the use of modern housing facilities that allow rearing quails at high densities. Some of these factors have favored the entrance and dissemination of avian pathogens, such Salmonella spp. The chicken-adapted Salmonella serovar Gallinarum biovars Pullorum and Gallinarum are responsible for pullorum disease and fowl typhoid, respectively (Barrow & Freitas Neto, 2011). Studies to assess the presence of Salmonella spp. in quails could generate information to allow the establishment of programs to control Salmonella in poultry production and to prevent human foodborne diseases
