Fumonisins in corn cultivars in the state of São Paulo

Abstract

Twenty three samples, belonging to 19 corn cultivars with distinct types of germoplasms, endosperm and length of vegetative cycle, were analyzed for fumonisins B 1 and B 2. The cultivars were grown in experimental fields in three locations (Votuporanga, Ribeirão Preto and Capão Bonito) within the State of São Paulo, Brazil, during the 97/98 crop. All samples were contaminated with fumonisins with concentrations ranging from 1.63 µg/g to 25.69 µg/g with an average of 5.61 µg/g for FB 1 and from 0.38 µg/g to 8.60 µg/g with an average of 1.86 µg/g for FB 2. In terms of fumonisins, these high levels put the corn cultivated in São Paulo among the most contaminated in the world reported to date.

Fumonisins in brewers grain (barley) used as dairy cattle feed in the State of Bahia, Brazil

“…This is a pioneer Wnding in the State of Bahia and suggests the presence of the main fungi that produce these toxins, considered to be highly adapted to tropical climate. Similar results have also been reported by Camargos et al (2000) who analyzed the presence of FB 1 in sorghum grains in the State of São Paulo. The highest incidence of contamination (88.5%) was observed in corn grains collected in the same state .…”

Fumonisins B1 and B2 in corn-based products commercialized in the state of Santa Catarina - Southern Brazil

“…Francheschi et al (1990) linked the rise in the development of EC in north-eastern Italy to increased corn consumption, in which polenta is the main basic food (Doko and Visconti, 1994) with a possible relation to a human carcinogenic In Brazil, it has been related to outbreaks of toxicosis in animals (Meirelles et al, 1994;Sydenham et al, 1992). There are records of the occurrence of fumonisins in corn and corn-based products, particularly in the Southern and Southwestern regions of the country, with levels that vary from 0.02 to 49.31µg/g for FB 1 and from 0.05 to 29.16 µg/g for FB 2 (Camargos et al, 2000;Hirooka et al, 1996;Ono et al, 2000Ono et al, , 2001Ono et al, , 2002Orsi et al, 2000). In Santa Catarina, FBs studies reported up to 97.3 % of the corn sold is contaminated.…”

Impacto das Fumonisinas, Aflatoxinas e Ocratoxina A na Avicultura

“…As médias de contaminação variaram de 1,63 -25,69 μg g -1 para FB 1 e de 0,38 -8,6 μg g -1 para FB 2 (CAMARGOS et al, 2000). Westhuizen et al (2003), analisaram 75 amostras de milho, destinadas ao consumo humano, provenientes das regiões oeste, norte e sul do Estado de Santa Catarina e 15 amostras de milho destinado ao consumo animal da região sul do estado, e detectaram médias de fumonisinas totais (B 1 + B 2 + B 3 ) de 3,2, 3,4, 1,7 e 1,5 μg g -1 , respectivamente.…”
