| Nos últimos anos o Brasil atingiu um grande destaque no cenário agrícola internacional, consolidando-se como um dos maiores produtores de commodities agrícolas como soja, milho, café, açúcar, entre outras. Como efeito do modelo agrícola adotado pela maioria dos produtores, visando aumento da produtividade e aumento da área cultivada, o Brasil também tornou-se um dos maiores consumidores de agrotóxicos do mundo (KUGLER, 2012), uma vez que este insumo é imprescindível neste modelo de agricultura. Com o aumento no consumo de agrotóxicos as preocupações com os resíduos destas substâncias em alimentos ganham evidência e tornam- se cada vez mais frequentes. No Brasil várias iniciativas têm sido implementadas com o intuito de garantir níveis seguros de resíduos... |

| Antibiotic resistance has increased in recent years, raising the concern of public health authorities. We conducted a study of Escherichia coli isolates obtained from human and food samples to assess the prevalence of antimicrobial resistance and to determine the genotype and clonal relationship of 84 E. coli isolates (48 from humans and 36 from foods). An antimicrobial susceptibility test was performed using the disk diffusion method. Virulence factors were evaluated by multiplex PCR, and the clonal relationship among the resistant isolates was studied by Pulsed Field Gel Electrophoresis (PFGE). All isolates were susceptible to ceftriaxone. Overall, 26%, 20.2%, 15.4% and 6% of the isolates were resistant to tetracycline, ampicillin,... |

| Abstract This study evaluated the microbiological quality of minimally processed vegetables commercialized in the city of Brasilia, DF, Brazil. A total of 32 samples of different vegetables were purchased from 10 supermarkets. In most samples (78.1%) the populations of psychrotrophic bacteria had a high count ranging from 106 to 108 CFU/g. Thermotolerant coliforms were found in all samples, with populations higher than 102 MPN/g in 15 samples (46.9%). After molecular analyses, E. coli was identified in 16 samples (50.0%) and Salmonella spp. in 4 samples (12.5%). S. aureus was found in 14 samples (43.8%), with counts higher than 103 CFU/g in 4 samples (12.5%). The results obtained in this study showed that 16 samples (50%) were unfit for consumption... |
