Resumo: |
Although the continuos growth of dairy cattle and its portion in human alimentation as one of most important source of animal protein, many Brazilians consume milk without any processing, that is, fresh milk, which, in many cases, has compromised its quality, such as under physicochemical and microbiological patterns, and the presence of contaminants or residues above the levels permitted by legislation. In the last years, the quality matter and food safety has been of major concern by the authorities, producers, industry and professionals responsible for food quality and by consumers. The piece of work has the objective to evaluate the quality of fresh milk dairy cattle agains the presence of microbial contamination and antimicrobial residues. For that, 42 samples of milk were analised from properties in the city of Brejão-PE, which were submitted to microbial culture for identification of Staphylococcus spp., realization of antibiogram gains penicillin, amoxicillin, tetracycline, streptomycin and gentamicin and for detection of microbial residues through the qualitative microbial inhibition test (ECLIPSE-50 ®). In 88,09% of the samples Staphylococcus spp. grew from the analised strains, 97,62% presented resistance to some antimicrobial analysed, observing 76,19% resistance to Gentamicin, 83,33% to streptomycin, 80,95% to tetracycline, 33,33% to amoxicillin and 47,62% to penicillin. In relation with the presence of antimicrobial residues, in 45,24% were detected levels above permitted limits in the qualitative analysis. It is concluded that the milk samples comercialized in the city of Brejão present chemical and biological contamination, making them inappropriate to human consume. |
