Daily intake estimates of fumonisins in corn-based food products in the population of Parana, Brazil

Abstract

a b s t r a c tOne hundred (100) samples of corn-based food products were collected between February 2007 and July 2010 to estimate the intake of fumonisins in the state of Paraná, Brazil. The identification of fumonisins was performed by high-performance liquid chromatography with fluorescence detection and post column o-phthaldialdehyde (OPA) derivatisation. The occurrences of fumonisins B 1 (FB 1 ) and B 2 (FB 2 ) were 82% and 51%, respectively, with concentrations ranging from 126 to 4348 mg/kg (FB 1 þ FB 2 ). Among corn-based products, corn meal had a higher prevalence of fumonisin (96.6%), and corn grits had the highest level of contamination (3462 mg/kg for FB 1 and 886 mg/kg for FB 2 ). The average probable daily intake (APDI) and maximum probable daily intake (MPDI) estimated for the population of Parana, Brazil, were 120.58 and 256.07 ng/kg body weight/day, respectively, which is lower than the provisional maximum tolerable daily intake (PMTDI), 2000 ng/kg body weight/day.

Assessment of the Contamination Level by Fumonisins B1 and B2 of the Corn Food Products Available on Polish Consumer Market

“…In other studies fumonisins were present in 50% of cornflake samples (2/4), and the mean value was 30.5 µg/kg [26]. In Martin's et al studies, cornflakes showed significantly higher contamination by fumonisins, where the average values of B 1 and B 2 were 341 µg/kg and 87 µg/kg, respectively [24]. Bryła et al analyzed 19 samples of cornflakes, from which nine were contaminated by B 1 and B 2 in the range of 13 to 248 µg/kg [27].…”

“…The analyzed samples of corn grits were free from contamination with B 2 (Table 2). Martins et al observed fumonisins in 19 samples of corn grits (67.9%), where high levels of B 1 and B 2 were found in concentrations ranging from 91 to 3,462 μg/ kg and from 45 to 886 μg/kg, respectively [24].…”

“…The results obtained by Chilaka et al showed that fumonisins were the most dominant mycotoxins occurring at high levels and incidence rates in all food types, especially in maize samples. From the total of 136 samples, B 1 was detected in 88 samples (65%) and B 2 [24].…”

Avaliação de biomarcadores da exposição humana à fumonisina B1 nos alimentos em municípios dos estados de São Paulo e Santa Catarina, Brasil

“…Fusarium verticillioides e F. proliferatum são os principais produtores de fumonisinas, os quais possuem elevada ocorrência em milho e seus derivados (FIGUEIRA et al, 2003). O milho (Zea mays L.) possui elevado valor nutricional constituindo um produto básico de consumo humano (MARTINS et al, 2012). A produção anual de milho no Brasil girou em torno de 53 milhões de toneladas na safra de 2009/2010, sendo o terceiro maior produtor mundial do referido grão (MAPA et al, 2015).…”

Estudos realizados anteriormente no Brasil demonstraram a elevada incidência de contaminação por fumonisinas no milho e derivados, chegando a 100% de incidência em alimentos comercialmente disponíveis SCUSSEL, 2004;BITTENCOURT et al, 2005;MARTINS et al, 2012).…”
