Resumo: OBJECTIVES: The presence of mycotoxins in food has been associated with several human diseases, and health authorities have taken actions to decrease the ingestion of these compounds in the diet. A study was carried out to assess aflatoxins and ochratoxin A concentrations found in food, and to evaluate the potential risk to human health resulting from mycotoxin exposure. METHODS: Between July 1998 to December 2001, 366 food samples were analyzed, including peanuts and its products, nuts, maize, oat and/or wheat products, rice and beans. Samples were processed and the extracted mycotoxins were detected and separated using thin layer chromatography, and then quantified with fluorescence. RESULTS: Aflatoxins were detected in 19.6% of the samples: raw peanuts and its products, pop corn, maize and Brazilian nuts (>;2mg/kg). Peanuts and its products showed the highest levels of aflatoxin contamination (34.7%) with up to 1280 mg/kg of AFB1+AFG1 and 1706 mg/kg of total aflatoxins. Of the positive samples, AFB1 was detected in 98.5%, AFB2 in 93%, AFG1 in 66.7%, and AFG2 in 65.4%. Ochratoxin A was not detected (

Realizou-se pesquisa para analisar os níveis de aflatoxinas e ocratoxina A de alimentos para consumo e avaliar o potencial de risco da exposição humana a essas micotoxinas. MÉTODOS: Foram analisadas 366 amostras de alimentos consumidos no Distrito Federal, no período de julho de 1998 a dezembro de 2001, como amendoim e derivados, castanhas, milho, produtos de trigo e/ou aveia, arroz e feijão. As amostras foram processadas, e as micotoxinas extraídas, detectadas e quantificadas por fluorescência após separação em cromatografia camada delgada. RESULTADOS: Foram detectadas aflatoxinas em 19,6% das amostras, em amendoim cru e derivados, milho de pipoca, milho em grão e castanha-do-pará (>;2 mig/kg). Amendoim e derivados apresentaram maior incidência de contaminação por aflatoxinas (34,7%) com amostras contendo até 1.280 mig/kg de AFB1+AFG1 e 1.706 mig/kg de aflatoxinas totais. Das amostras positivas, AFB1 estava presente em 98,5%, AFB2 em 93%, AFG1 em 66,7% e AFG2 em 65,4%. A ocratoxina A não foi detectada (Universidade de São Paulo.
