Insect species and damage levels were evaluated and related to aflatoxin content in maize sampled from farmers' stores in four agroecological zones over a two-year period in Benin, West-Africa. In 1993, no aflatoxin was detected in maize that was free of isect damage. In the same year; in maize w...

The objective of this study was to evaluate the presence of Aspergillus section Flavi and A. section Nigri in cashew nuts harvested in the Northern Guinea (NG) and Southern Sudanian (SS) agro-ecological zones of Benin. Also, the presence of aflatoxins was investigated. For detection of fungal con...

Dried yam (Dioscorea spp.) chips are widely consumed in Bénin but are often attacked by molds. Invasion of food by Aspergillus flavus may lead to aflatoxin contamination. We report here the result of a survey on the sanitary quality of dried yam chips in Bénin. During July and August 2000, 50 dri...

The major mycotoxins studied at the Consultative Group on International Agricultural Re-search (CGIAR) institutes are aflatoxins in maize, groundnut, sorghum and cassava, Fusa-rium toxins in maize, wheat and sorghum, and ochratoxin in cocoa and cashew. Genetic en-hancement (both through plant bre...

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
From 1999 till 2001, management strategies for the reduction of aflatoxin in maize were developed in participatory tests with farmers. After 6 months of storage, maize in bags contained more aflatoxin than maize in traditional farmers’ stores. Harvesting maize late increased the risk of aflatoxin...

BACKGROUND: Maize constitutes the main staple food and most important crop grown in Zambia. However, maize incursconsiderable losses both in field and storage due to pathogens and insects. Some of the pathogens and resultant mycotoxinsreduce the nutritional quality of the product. Mycotoxins are ...
