Aflatoxin contamination of crops is frequent in warm regions across the globe, including large areas sub-Saharan Africa. Crop with these dangerous toxins transcends health, food security, and trade sectors. It cuts value chain, affecting farmers, traders, markets, finally consumers. Diverse fungi within Aspergillus section Flavi contaminate aflatoxins. Within communities, several genotypes are not capable producing aflatoxins (atoxigenic). Carefully selected atoxigenic biological control...
In this study an LC-MS/MS multitoxin method covering a total of 247 fungal and bacterial metabolites was applied to the analysis different foods feedstuffs from Burkina Faso Mozambique. Overall, 63 were determined in 122 samples mainly maize groundnuts few sorghum, millet, rice, wheat, soy, dried fruits, other processed animal feeds. Aflatoxin B1 observed more frequently (Burkina Faso, 50% incidence, median = 23.6 μg/kg; Mozambique, 46% 69.9 μg/kg) than 22% 10.5 14% 3.4 μg/kg). Fumonisin...
Aflatoxin contamination resulting from maize infection by Aspergillus flavus is both an economic and a public health concern. Therefore, strategies for controlling aflatoxin in are being investigated. The abilities of eleven naturally occurring atoxigenic isolates Nigeria to reduce were evaluated grain competition experiments field studies during the 2005 2006 growing seasons. Treatments consisted inoculation either grains vials or ears at mid-silking stage plots, with toxigenic isolate...
Aspergillus flavus has two morphotypes, the S strain and L strain, that differ in aflatoxin-producing ability other characteristics. Fungal communities on maize dominated by of A. have repeatedly been associated with acute aflatoxin poisonings Kenya, where management tools to reduce levels are needed urgently. isolates (n = 290) originating from produced Kenya belonging morphotype were tested for potential. A total 96 atoxigenic was identified four provinces sampled. The placed into 53...
Traditional and improved varieties of maize, pearl millet sorghum were planted by small-scale farmers under the direction International Institute for Tropical Agriculture in two Nigerian agro-ecological zones: Sudan Savanna Northern Guinea Savanna. Samples collected determination Fusarium infection fumonisin (B1, B2 B3) contamination. A previous paper reported Aspergillus aflatoxin contamination these samples. levels, measured per cent kernels infected, modest with mean levels above cereals...
Aflatoxin contamination in maize and groundnut is perennial Ghana with substantial health economic burden on the population. The present study examined for first time prevalence of aflatoxin major producing regions across three agroecological zones (AEZs) Ghana. Furthermore, distribution aflatoxin-producing potential Aspergillus species associated both crops were studied. Out 509 samples (326 183 groundnut), 35% had detectable levels aflatoxins. Over 15% 11% exceeded threshold limits set by...
The aims of the study were to quantify aflatoxins, potent carcinogens associated with stunting and immune suppression, in maize groundnut across Zambia's three agroecologies determine vulnerability aflatoxin increases after purchase. Aflatoxin concentrations determined for 334 samples from 27 districts using lateral‐flow immunochromatography. Seventeen per cent crops markets contained above allowable levels Zambia (10 μg kg−1). Proportions unsafe human consumption differed significantly (P...
Aspergillus flavus is the most common causal agent of aflatoxin contamination food and feed. However, aflatoxin-producing potential varies widely among A. genotypes with many producing no aflatoxins. Some non-aflatoxigenic are used as biocontrol agents to prevent contamination. Aflatoxin biosynthesis genes tightly clustered in a highly conserved order. Gene deletions presence single nucleotide polymorphisms (SNPs) often associated inability produce In order identify mechanisms...
Aflatoxin contamination of groundnut and maize infected by Aspergillus section Flavi fungi is common throughout Senegal. The use biocontrol products containing atoxigenic flavus strains to reduce crop aflatoxin content has been successful in several regions, but no such are available product Aflasafe SN01 was developed for four active ingredients A. genotypes native Senegal distinct from used other products. Efficacy tests on farmers' fields were carried out during the course 5 years. Active...
Aflatoxin contamination of important food and feed crops occurs frequently in warm tropical subtropical regions. The is caused mainly by Aspergillus flavus A. parasiticus. negatively affects health trade sectors causes economic losses to agricultural industries. Many pre- post-harvest technologies can limit aflatoxin but may not always reduce concentrations below tolerance thresholds. However, the use atoxigenic (non-toxin producing) isolates competitively displace producers a practical...
A New Disease Threat to Sorghum in the Americas and Australia orghum, bicolor (L.) Moench, is world's fifth most important cereal crop, cultivated on about 45 million hectares for food, feed, beverage, fodder.The significant technological change since 1960s has been development use of F 1 hybrid seed ( 14), which lead a dramatic improvement crop's productivity.Sorghum cultivation intensive, commercialized systems where yields average 3 5 t ha -1 relies almost totally seed.In contrast, vary...
Aflatoxins are a common contaminant of cereals that can cause cancer, liver disease, immune suppression, retarded growth and development, death, depending on the level duration exposure. Maize is an introduced crop to Africa there have been efforts over last 20 years or so replace traditional cereal crops, such as sorghum (Sorghum bicolor) pearl millet (Pennisetum glaucum), with maize. We found maize was significantly more heavily colonized by aflatoxin-producing Aspergillus spp. than either...
Despite massive expansion of human and livestock populations, fuelled by agricultural innovations, nearly one billion people are hungry 2 sickened each year from the food they eat. Agricultural systems intimately connected to health outcomes, but policy programs often stop at clinic door. A consensus is growing that disconnection between agriculture, nutrition least partly responsible for disease burden associated with farming. Mycotoxins produced fungi most serious safety problems affecting...
Mycotoxins are major food contaminants affecting global security, especially in low and middle-income countries. The European Union (EU) funded project, MycoKey, focuses on “Integrated innovative key actions for mycotoxin management the feed chains” right to safe through strategies regulation, which fundamental minimizing unequal access sufficient worldwide. As part of MycoKey a Mycotoxin Charter (charter.mycokey.eu) was launched share need harmonization legislation policies minimize human...
