“…Bento et al, [18] found aflatoxins in 19% and 23.8% of corn samples from Mato Grosso state harvested in 2009 and 2010 respectively, although at higher levels (1.0 to 108.7 µg/kg). 8% of 300 samples of freshly harvested corn collected in the reception and pre-drying steps in Paraná State had aflatoxins at mean concentration of 30.6 µg/kg [11]. However, the authors found fumonisins in 100% of the analyzed samples, with similar mean levels (2,082 µg/kg) as obtained in the present study.…”

“…Previous reports have indicated that the incidence of aflatoxins in Brazilian corn is highly variable, with mean levels of up to 460 µg/kg [10,11]. For fumonisins, higher incidences (up to 100%) were reported in corn, with mean levels ranging from 20-22,600 µg/kg [10][11][12].…”

“…35 The total fungi isolated were increased during rainy season and temperature rise similar as those reported for other regions. 36,37 Mycobiota isolated from several feed samples were comparable to species found by other researchers from the same substrate in Brazil, Argentina, France and Egypt being potentially toxigenic species A. flavus, A. parasiticus, A. fumigatus, A. niger aggregate, P. citrinum, F. verticillioides and F. graminearum prevailed on this substrate. Aspergillus flavus and A. fumigatus relative density in post-fermentation silage samples was higher than in pre-fermentation samples.…”

Research ABSTRACTBrazil has regions located at the largest dairy production and milk derivate industry concentration, supplying the major consumer markets, represented by São Paulo, Rio de Janeiro and Belo Horizonte Cities. The milk is the most important product of Brazilian agriculture, because it is always presents in daily diet. The aim of this research was evaluating the occurrence of mycotoxins in the feed of dairy cattle and the occurrence of AFM 1 in milk under field conditions in farms from Rio de Janeiro State, Brazil. The results revealed that, total fungal counts was found in 67% of feed samples which exceeded the recommended limit recommended (1×10 4 UFC.g -1 ) and the incidence of AFM 1 in all milk samples was 26.7% at concentrations ranging from 0.010 to 1.500 μg.L -1 . The study revealed toxigenic fungi and their mycotoxins were present in feed intended for bovine feeding in Rio de Janeiro farms. Evaluations of mycotoxin levels are important to provide information so that the assessments of risk for animal feed and livestock environment can be done.

“…No Brasil, a contaminação de alimentos por fumonisinas tem sido tratada por diversos autores, de maneira especial no milho e derivados (Bittencourt et al, 2005;Moreno et al, 2009;Bordin et al, 2014), contudo não há estudos que avaliem os níveis de FB 1 e ácido fólico na dieta, ou a associação entre essas variáveis e as concentrações séricas de ácido fólico.…”

RESUMO: Neste trabalho foram determinados os níveis de ácido fólico e de fumonisina B1 (FB1) em farinha de milho consumida por 24 voluntários residentes em um campus universitário no estado de São Paulo, bem como sua relação com as concentrações de ácido fólico sérico nos indivíduos. As análises de ácido fólico e de FB1 em farinha de milho foram realizadas por cromatografia líquida de alta eficiência (CLAE), enquanto a determinação de ácido fólico sérico foi feita por kit de imunoensaio. Detectou-se a FB1 em 100% das amostras de farinha de milho, em níveis que variaram de 142 a 3.037 µg kg-1 (média: 738 ± 591 µg kg-1). As concentrações de ácido fólico nas amostras de farinha de milho ficaram entre < 0,3 µg kg-1 (limite de quantificação) e 1.705 µg kg-1, com média de 713 ± 435 µg kg-1, o que representa 47% do limite mínimo exigido pela Agência Nacional de Vigilância Sanitária (ANVISA) para farinhas de milho comercialmente disponíveis. Nas amostras de soro humano, os níveis de ácido fólico variaram de 6,7 a 24,0 ng mL-1 (média: 13,4 ± 5,4 ng mL-1). Não houve correlação (p < 0,05) entre os níveis de ácido fólico no soro dos indivíduos e as concentrações de FB1 ou ácido fólico nas amostras de farinha de milho. Outros estudos são necessários para estimar a ingestão total de FB1 por meio da dieta para averiguar os efeitos das fumonisinas sobre a absorção de ácido fólico nos indivíduos avaliados.
