| The histopathological effects of fumonisin B1 (FB1) injected intraperitoneally (IP), was evaluated in catfish (Ictalurus punctatus). Fishes were divided into four Groups. Groups II, III and IV were treated IP with FB1 injections of 1; 5 and 10 mg/kg bw/day, respectively, during 21 days. At the 7th, 14th and 21st day, fishes were sacrificed. The livers were hystologicaly analysed by the light and transmission electronic microscopy. Livers from the 7th day showed organelles alterations, particularly in the granular endoplasmatic reticle, mitochondria, nucleus and nucleolus mediated by FB1 doses. The occurrence of processes involved in the necrosis and apoptosis was detected. At the highest FB1 dose,the livers presented an intense response with an accentuate... |

| Corn flour, "canjica" (corn grits), corn flakes and popcorn for human consumption, commercialized in Santa Catarina (n=82), were analyzed in order to detect the presence of fumonisins B1 (FB1) and B2 (FB2). From the samples, 92.68% showed detectable levels of Fumonisins (FBs). Corn flour showed the highest level of contamination (91.5%) with average levels of 3.811 and 5.737 mg/g for the home-processed and industrialized products, respectively. The next most contaminated product was popcorn with a average of 2.872 mg/g and an occurrence in 91.6% of the samples. All samples of corn flakes were contaminated with an average of 1.307 mg/g. The product with the lowest levels of FBs was "canjica" with a average contamination of 0.732 mg/g. These results... |

| Toxigenic fungi were studied in beans (Phaseolus vulgaris L.) of Classes black and color, cultivated in different regions of the State of Santa Catarina, south region of Brazil. The mean counts of filamentous fungi were 2.8 x 103 and 6.7 x 103 CFU/g for beans Classes black and color, respectively. Penicillium spp., Aspergillus spp. and Phoma spp. were the most frequent genera isolated, followed by Ryzopus spp., Alternaria spp., Helminthosporium spp., Cladosporium spp., Botrytis spp., Fusarium spp., Trichoderma spp., Curvularia spp. and Dreschelera spp. Among beans Class black, 24.6% of the Aspergillus strains produced mycotoxins: 13.1% produced aflatoxins (AFs); 11.5% produced ochratoxin A (OTA) and 28.9% of Penicillium produced citrinin (CTR). On the... |
