Abstract
Salmonella is hazard to food safety. This study investigated the presence of Salmonella sp in normal and condemned heart and liver samples from broilers. These specimens were subdivided into pools of five samples, which were processed according to the recommend procedure by Brazilian legislation. A total of 9.24% of these pools were Salmonella positive, which corresponded to 5.41% of normal hearts and 25.00% of condemned livers. Salmonella Enteritidis was isolated from two normal heart pools and seven condemned livers pools. Of these positive samples, Salmonella Typhimurium was isolated from two pools. The isolated strains were tested for antimicrobial susceptibility profile to thirteen antimicrobial agents. Of two Salmonella Enteritidis strains isolated from normal hearts, one showed resistance to one of the tested antimicrobial drugs. The other strain was susceptible to all the tested antimicrobial drugs. This bacterium sorovar isolated from condemned livers was susceptible to all of the evaluated antimicrobial drugs. Salmonella Typhimurium was isolated from two pools, which showed concomitant resistance to four antimicrobials agents. The other strain showed to be sensitive to all of the tested drugs. These data show that chicken giblets, which are commonly available in markets, could be a source for Salmonella sp transmission. It might represent a risk to public health as the isolated Salmonella Typhimurium showed multiresistance to the evaluated antimicrobial agents.
