Mycotoxin research in Brazil: the last decade in review

Abstract: The number of research papers (128 papers) on mycotoxins published by Brazilian researchers in 1991-2000 surpassed the total number (85 papers) published in the preceding three decades . Thirty percent of the papers surveyed mycotoxins in foods and feeds. AFs in peanut and peanut products continued to be alarming, and high incidence and levels of FBs in corn and corn products also appeared as a serious problem. Contamination with other toxins, such as ZEA, OTA and trichothecenes, was low. Occurrence of AFM 1 i… Show more

“…For example, Nakai et al (2008) studied the occurrence of aflatoxins in stored peanut samples from the State of São Paulo, Brazil, and found mean levels of AFB1 from 7.0 to 116.0 µg/kg. In a review of mycotoxin research in Brazil from 1991 through 2000, Rodriguez-Amaya and Sabino (2002) reported aflatoxin contamination in peanuts and peanut products from 1.0 to 12.9 µg/kg Sabino et al (1999), researching the occurrence of aflatoxins in peanuts and peanut products consumed in the State of São Paulo, Brazil, concluded that aflatoxin contamination in peanuts is decreasing but remains a problem because the maximum level of contamination detected was 536.0 µg/kg. However, few studies of aflatoxin contamination have been conducted in the southernmost region of Brazil.…”

“…The State of São Paulo is the greatest peanut producer, with a peanut output estimated to be 80.9 thousand tons for the 2008/2009 harvest, representing 71% of the Brazilian national peanut production (CONAB, 2010). The quality of peanuts and their derivatives consumed in southeastern Brazil is frequently monitored (Nakai et al 2008;Rodriguez-Amaya and Sabino 2002;Sabino et al 1999;Freitas and Brigido 1998 (CONAB 2010). In this region, peanuts are cultivated on a small scale by rural producers.…”

“…É crescente o número de publicações dedicadas ao estudo da ocorrência dessas substâncias no país, focalizando principalmente a contaminação alimentar e de rações animais 10 em detrimento das exposições humanas e suas consequências. Existem no país alimentos de origem animal e vegetal com importantes concentrações de aflatoxinas, dos quais se destacam o milho em grão, o amendoim, a castanha-do-pará (extraída na Região Norte e que abastece o mercado interno), o leite e muitos outros 8,9,10,11 . O Programa Nacional de Controle de Resíduos e Contaminantes (PNCRC) do Ministério da Agricultura, Pecuária e Abastecimento que tem o objetivo de inspecionar e fiscalizar alimentos de origem vegetal e animal, bem como a Agência Nacional de Vigilância Sanitária (ANVISA) estabelecem limites máximos que variam entre 0,5 e 20µg/kg para aflatoxinas em alimentos e produtos a serem ofertados ao consumidor 39,40 .…”

“…Devido aos seus efeitos carcinogênicos, a exposição humana a tais substâncias representa um fator importante a ser considerado na etiologia do câncer hepático. Há evidências de contaminação dos alimentos no país, especialmente o milho em grão, o amendoim e seus derivados, a castanha-do-pará, o leite, entre outros 8,9,10,11 .…”

“…São conhecidas 18 diferentes moléculas do grupo das aflatoxinas, mas a aflatoxina B 1 é considerada uma das substâncias carcinogênicas mais conhecidas e também uma das mais isoladas dos alimentos contaminados (Zeringue et al 1993). Pesquisas realizadas em várias regiões no Brasil demonstraram a presença de altos teores de AFB 1 em grãos de milho antes e após a colheita e em ingredientes de rações (Rodríguez-Amaya & Sabino 2002, Rocha et al 2009), sendo frequente o envolvimento desses metabólitos em patologias de animais e, em especial, na bovinocultura leiteira. Assim, o presente trabalho teve por objetivos avaliar o perfil da micobiota, a atividade de água e a presença de AFB 1 nas dietas completas fornecidas as vacas em lactação em fazendas leiteiras no estado de São Paulo.…”
