| Resumo: | Survey results of 321 samples of groundnuts (peanuts) and groundnut products obtained from the Inspection Service of the Sanitary Guidance of the Hea1th Secretary of São Paulo (totaling 321 samples) collected in an one-year period (1994) showed levels of aflatoxins BI and G1 above 30.0 ug.kg' for 36% ofthe samples. All samples were analyzed by thinlayer chromatography and results quantified by visual analysis. The aflatoxins concentration of the samples varied from 5.0 to 2440.0 ug.kg' and the 90th percentil was 489.0 ug.kg'. A total of 116 samples (36%) showed concentrations greater than permitted by Brazilian Legislation which, for aflatoxins BI + G1, is 30.0 ug.kg' for food (domestic consumption). The limit of determination of the method was 5.0 ug.kg'. This survey reconfirmed the extent and level of occurrence of aflatoxins in groundnuts and groundnut products in São Paulo and also showed that the mycotoxin problem still exists, mainly due to conditions of temperature and humidity prevalent in the State of São Paulo that are favorable to the growth of toxigenic moulds. |
