摘要:The objective of this work was to evaluate the microbiological conditions of chicken
carcasses, with regards to S. aureus count. Thirty carcasses of chicken in natura
and 31 refrigerated carcasses of chicken acquired in public markets and
supermarkets were analyzed, respectively. In 58 (91.1%) of the samples,
Staphylococcus sp. were isolated, from which 40 (65.0%) presented
Staphylococcus aureus and 18 (31.0%) coagulase negative Staphylococcus (CNS).
Staphylococcus aureus count and CNS varied between 10 to 106 CFU/g of chicken
meat. The refrigerated chicken carcasses presented lower counting of S. aureus
in relation to carcasses of chicken in natura, showing a direct co-relation between
the commercialization temperature of the product and the count of these bacteria.
Seventy-eight (87.6%) of typical colonies and 48 (40%) atypical colonies of S.
aureus were confirmed in Baird-Parker agar. It was concluded that the
microbiological standards for S. aureus in chicken carcasses in natura and
refrigerated needs to be adopted for the obtention of high quality products for the
consumer and that the atypical colonies of S. aureus in Baird-Parker agar should
be considered by food analysts.
