In this study an LC-MS/MS multitoxin method covering a total of 247 fungal and bacterial metabolites was applied to the analysis of different foods and feedstuffs from Burkina Faso and Mozambique. Overall, 63 metabolites were determined in 122 samples of mainly maize and groundnuts and a few samp...

Quantitation of mycotoxins in food and feed from Burkina Faso and Mozambique using a modern LCMS/MS multitoxin method
Food safety and compliance with international standards is a major challenging to achieve food security in sub-Saharan Africa. The present study evaluated the occurrence of Aspergillus flavus, Fusarium spp., and related fungi, and resultant aflatoxins and fumonsins in dried cassava and ...

Aflatoxin and fumonisin contamination of cassava products and maize grain from markets in Tanzania and republic of the Congo
Pre- and 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 pre- and postharvest toxin contamination in maize. Sound crop management practices are an eff...

Preandpostharvest management of aflatoxin in maize: an African perspective
Fungal communities in soils of Nigerian maize fields were examined to determine distributions ofaflatoxin-producing fungi and to identify endemic atoxigenic strains of potential value as biologicalcontrol agents for limiting aflatoxin contamination in West African crops. Over 1000 isolates belong...

Distribution of Aspergillus section Flavi in soils of maize fields in three agroecological zones of Nigeria
Aspergillus flavus has two morphotypes, the S strain and the L strain, that differ in aflatoxin-producing ability and other characteristics. Fungal communities on maize dominated by the S strain of A. flavus have repeatedly been associated with acute aflatoxin poisonings in Kenya, where managemen...
