Aflatoxin contamination (AC) in maize, caused by the fungal pathogen Aspergillus flavus(Link), starts at pre-harvest stage. Hence, interventions that reduce entry and development of A. flavus in the field are required. Trials were carried out at Seatondale and Igeri, to evaluate the effects of ni...

Four storage systems of maize commonly used by farmers in Benin, West Africa, were tested to determine their impact on infection of maize by Fusarium and subsequent contamination with fumonisins. The study showed that Fusarium incidence was significantly higher when maize was stored on a cemented...

Aflatoxin B1 (AFB1) is a carcinogenic mycotoxin produced by Aspergillii of the section Flavi that may contaminate food, in the field or during storage. Cassava represents an important staple food in sub-saharian Africa. The analysis of aflatoxigenic fungi in 36 cassava samples obtained from produ...

This article sets the background for an exciting new linkage between Australian and Africa-based scientists who will use NIR to enhance the safety and value of traditional African crops. It has long been advocated that NIR spectroscopy should be deployed in this fashion because of its inherent ad...
