Traits related to nitrogen fixation may be used as indirect selection criteria foraflatoxin resistance in peanut. The aim of this study was to investigate therelationship between N2 fixation traits and aflatoxin contamination in peanut underdifferent drought conditions. Eleven peanut genotypes were evaluated under threewater regimes for two seasons in the field. Data were observed on kernel inf...

Many studies have shown that mycotoxin contamination of agricultural products is a challenge for individual's health especially in developing countries. Improper production and storage of foods, prepare conditions for aflatoxin production in crops, especially rice, wheat, pistachio, walnut, almond, etc which are the main sources of foods for people. Feeding livestock by contaminated bread is an...

introduction: aflatoxin b1 (afb1) is one of the most well-known hepatocarcinogens in humans. contamination of raw materials, used in the production of sausages and burgers, with aflatoxin producing molds can lead to increased level of aflatoxin in the final products and can impose hazards to human health. unfortunately, aflatoxin is resistant to heating and freezing processes, etc. and can rema...

ABSTRACT Aflatoxins are toxic fungal metabolites produced by several members of Aspergillus section Flavi. U.S. federal regulations limit the use of aflatoxin-contaminated cottonseed. Cottonseed with aflatoxin content of 20 ng/g or higher may not enter the profitable dairy market. Between 4,472 and 9,949 truckloads of cottonseed from 31 to 35 gins in South Texas were analyzed for aflatoxin cont...

Aflatoxins are highly toxic compounds that are produced as secondary metabolites by some Aspergillus and Emericella species. Despite huge progress on aflatoxin research during the past 50 years, we have witnessed many cases of food contamination with aflatoxins all over the world. Aflatoxins have mutagenic and carcinogenic effects and they are capable of inducing hepatocellular carcinoma in hum...

Aflatoxin contamination resulting from maize infection by Aspergillus flavus is both an economic and a public health concern. Therefore, strategies for controlling aflatoxin contamination in maize are being investigated. The abilities of eleven naturally occurring atoxigenic isolates in Nigeria to reduce aflatoxin contamination in maize were evaluated in grain competition experiments and in fie...

Aflatoxin, the fungal carcinogen first identified in 1960, is now recognized as the prototypical laboratory carcinogen. It causes mutations in the p53 tumor-suppressor gene as well as ras mutations, which are involved in the majority of human cancers. Aflatoxin has been shown to contaminate tobacco products. Tobacco-related cancers, including those associated with ETS, often show the same p53 m...

Five strains ofAspergillusfJavus lacking the ability to produce aflatoxins were examined in greenhouse tests for the ability to prevent a toxigenic strain from contaminating developing cottonseed with aflatoxins. All atoxigenic strains reduced contamination when inoculated into developing bolls 24 h prior to the toxigenic strain. However, only one strain, AF36, was highly effective when inocula...

Preand postharvest contamination of aflatoxin in maize is a major health deterrent for people in Africa where maize production has increased dramatically. This chapter highlights management options for preand postharvest toxin contamination in maize. Sound crop management practices are an effective way of avoiding, or at least diminishing, infection by Aspergillus jlavus and subsequent aflatoxi...

This paper presents an overview of reports of aflatoxin contamination in various foods and products, which have been carried out in Thailand between 1967-2001. Thirteen available international and local reports (n=3,206 samples) focused on type of food, season and geographic areas, and have been collected for statistical analysis. The accumulated data showed 1,248 (38.9%) of 3,206 samples were ...
