| ABSTRACT The present study investigated the frequency, level of contamination and serotyping of Salmonella strains isolated from broiler flocks in different processing sites and the fulfillment of a Performance Objective (PO) in frozen chicken breasts, as a risk assessment to measure the efficacy of prevention and control programs applied to reduce the risk of Salmonella spp. in raw poultry meat that contribute to reach food safety and public health goals. From 1,800 samples of cloacal swabs, carcasses before and after immersion chilling and frozen breasts derived from 20 broiler flocks slaughtered at two processing plants located in the mid-west and southern regions of Brazil, 278 samples were positive for Salmonella spp. by polymerase chain reaction... |

| ABSTRACT The extensive use of antimicrobial agents has contributed to the emergence of antimicrobial resistance and multidrug resistance (MDR) in Salmonella, an important zoonotic pathogen that causes outbreaks and sporadic cases of gastroenteritis in humans. The study aimed to investigate the antimicrobial resistance profile of Salmonella strains isolated from poultry in Brazil. A total of 230 Salmonella strains, isolated from cloacal swabs (n=56) and broiler carcasses swabs (n=174) before and after chilling from slaughterhouses under Federal Inspection Service within the period 2012-2017, were analyzed. Serotyping and antibiotic susceptibility testing were performed on all the isolates. Serotyping results showed that 41% of the strains were Salmonella... |

| ABSTRACT The present study investigated the effectiveness of a single Salmonella prevention and control program applied in two different processing plants, located in the states of Mato Grosso do Sul (plant A) and Santa Catarina (Plant B), belonging to the same company, and identified Salmonella strain subtypes isolated from broilers, carcasses before and after chilling, and frozen chicken breasts. The Salmonella prevention and control program was 90% effective in plant A and 100% in plant B, considering a level of 10% positive samples per frozen chicken breast batch acceptable. A total of 128 strains were serotyped, being 10 from drag swabs, 31 from cloacal swabs, 83 from carcasses, and 4 from frozen chicken breasts. After serotyping analysis, 30 strains... |
