SUMMARY:

There are numerous causes of condemnation in the inspection lines of broilers, among them, bruises and fractures are relevant causes, leading to economic losses to the sector. In addition to the financial losses due to partial and total condemnation of carcasses and destinations for industrialization, bruises and fractures are characterized as quality problems, as they occurduring human or technological failures. The aim of this work was to evaluate the microbiological risk related to bruises and fractures in parts of broiler carcasses that are removed, condemned or destined for industrialization. Recent bruises and fractures were evaluated, classified as technological failures during the industrial processing stages. The bruise samples were divided into chest (n=18), wing (n=18) and leg (n=28), totaling 64 samples. The samples were classified into four subgroups (control, mild, moderate, severe) according to the degree of injury, considering the macroscopic aspect of the piece and color. Fractures samples were evaluated in wing (n=22) and leg (n=15), totaling 37 samples. The samples were classified into three subgroups (control, white or red fracture) according to the presence or absence of hemorrhage. For each collected sample, of bruises and fractures, including the control group, five microbiological analyzes were performed to count Salmonella spp., mesophilic aerobes, Escherichia coli, Staphylococcus aureus and Clostridium perfringens. In all analyzed samples of bruises nor fracture, no microbial growth for S. aureus, C. perfringens and Salmonella spp. were assessed. There was growth of mesophilic aerobes and E. coli., which are indicators of hygiene and handling, but at levels equivalent to those found in the control groups, that is, there was no increase in bacterial count in samples with bruise or fracture. It is concluded that the parts affected by recent bruises and fractures, according to the results obtained, tend to be safe for consumption, as long as correct measures for good manufacturing practices are adopted to avoid cross-contamination of these parts.
