Aspergillus section Flavi have been implicated as causal agents of aflatoxin contamination in Africa. However, Aspergillus populations associated with aflatoxin contamination in Zambia have not been adequately detailed. Most of Zambia's arable land is non-cultivated and Aspergillus communities in...

Aspergillus section Flavi community structure in Zambia influences aflatoxin contamination of maize and groundnut
Ochratoxin A (OTA) is a mycotoxin commonly associated with many food and beverage crops grown in tropical and temperate regions. There is no data available regarding OTA contamination of ready for sale cocoa beans in Nigeria. The objective of this study was to assess the levels of OTA contaminati...

Mycotoxins are toxic to humans and animals when present in food and feed above tolerance limits. Reduction in mycotoxin exposure of humans and animals has necessitated regulatory interventions by some national governments and international agencies. Conservative estimates of lost crop revenues, a...

The mycotox charter: increasing awareness of, and concerted action for, minimizing mycotoxin exposure worldwide
A pilot, cross-sectional, correlational study was conducted in eight rural communities in northern Nigeria toinvestigate mycotoxin exposures in 120 volunteers (19 children, 20 adolescents and 81 adults) using a modernLC–MS/MS based multi-biomarker approach. Firstmorning urine samples were analyze...

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 t...
