| Exposure to aflatoxins (AFs) in the diet may favour the development of hepatocellular carcinoma (HCC) and the acute exacerbation of hepatitis in chronic hepatitis B virus (HBV) carriers. Measurement of biomarkers such as aflatoxin M1 (AFM1), a metabolite of aflatoxin B1 (AFB1), in urine allows for the assessment of populations exposed to aflatoxins. The aim of this study was to investigate the occurrence of aflatoxin M1 in the urine of HBV carrier and non-carrier patients. One group included 43 randomly selected HBV carriers treated at two hospitals in the city of Maringa, Brazil, from March to June 2008. Control group consisted of 29 healthy adult volunteers with anti-HBs positive and HBsAg negative test results. Detection of AFM1 was performed by... |

| Fluctuations in the Brazilian milk market force small milk producers to find temporary trade alternatives, which include selling raw milk to people who prefer this type of milk rather than heat-processed milk. Considering the importance of these small milk producers to the market and the well-known health risks associated to consumption of raw milk, this study evaluated the microbiological quality and the presence of Listeria monocytogenes, Salmonella spp., chlorine, antimicrobials and insecticides (organophosphates and carbamates) in raw milk produced in 210 small and medium farms located in four important milk-producing Brazilian states (Paraná, São Paulo, Minas Gerais and Rio Grande do Sul). In 66% of the selected farms the milking was manual. In 33% of... |
