Qualidade microbiológica da carne caprina (capra hircus, Linneaus, 1778) comercializada na cidade do Recife

Abstract

Evaluation of microbiological quality of chilled and in natural goat meat sold in public/private markets and supermarkets of Recife concerning Staphylococcus aureus counting, total and thermotolerant coliforms,identification and typing of Salmonella spp, was the objective of this study. Antimicrobial sensibility profile in vitro of Staphylococcus aureus and Salmonella spp samples and the correlation between the simultaneous presence of faecal coliforms and Salmonella spp. were also performed. The study was carried out at six public/private markets and nine supermarkets of Recife, which were selected according to the administrative division of Local Authority Healthy General Office in six sanitary districts. A total of 24 samples of goat meat, 14 proceeded from public/private markets in natura and 10 chilled ones from supermarkets. Samples were processed using methodologies recommended by the Agriculture, Pecuary and Provision Ministry. Results demonstrated that 11 samples (45,83%) presented positive coagulasis staphylococcus (SCP) varying from 6.7 x 103 to 1.4 x 106 UFC/g, corresponding to 27 isolated from a total of 89. In total coliforms analyses, five samples (20.83%) presented satisfactory sanitary conditions and 19 (79.16%) had countings varying from 4.3 x 103 to 3.7 x 107, thermotolerants coliforms were detected in 15 (62.5%), which countings varied from 2 x 104 to 2.5 x 107 UFC/g and nine samples (37.5%) presented satisfactory sanitary conditions. Presence of Salmonella spp., was confirmed at seven samples (29.17%) in which eight sorovares were typed: four (50%) Salmonella enterica subsp houtenae (O:53), two (25%) S. Anatum, one (12.50%) S.Rubislaw and one (12, 50%) S. Derby. No correlation was observed among coliforms and Salmonella presure. Antimicrobial profile sensibility showed that S. aureus were sensitive to norfloxacin and vancomicin (100%), tetraciclin and sulpha + trimetoprim (96.30%) and oxacilin (87.50%) and 100 % of Salmonella spp. samples were sensitive norfloxacin, 75% sulpha + trimetoprim and 62.5% tetraciclin. It is concluded that goat meat sold at markets and supermarkets of Recife presented undesirable microbiological patterns emphasizing the importance of a strong supervision at the productive goat meat chain as well as a revision of the Resolution of Collective Management from the National Agency of Sanitary Vigilance, (RDC, n°12/2001) which does not establish microbiological patterns for the coliforms and Staphylococcus spp countings in chilled and in natura goat meat.
