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...

The distribution and aflatoxigenicity of Aspergillus section Flavi isolates in 58 commercial poultry feed samplesobtained from 17 states in five agro-ecological zones (AEZs) in Nigeria were determined in order to assess thesafety of the feedswith respect to aflatoxin-producing fungi. Correlation ...

Dried insects and fish are important sources of income and dietary protein in Zambia. Some aflatoxin-producing fungi are entomopathogenic and also colonize insects and fish after harvest and processing. Aflatoxins are carcinogenic, immune-suppressing mycotoxins that are frequent food contaminants...

The ability of superabsorbent polymers (SAP) in drying maize and controlling aflatoxin contamination was studied under different temperatures, drying times and SAP-to-maize ratios. Temperature and drying time showed significant influence on the aflatoxin formation. SAP-to-maize ratios between 1:1...

Aflatoxins are highly toxic carcinogens that contaminate crops worldwide. Previous studies conducted inNigeria and Ghana found high concentrations of aflatoxins in pre- and post-harvest maize. However,little information is available on the population structure of Aspergillus Sect. Flavi in West A...

The aim of the study was to determine the geographical and seasonal variations in aflatoxin dietary exposure levels
in adults from Senegal. A total of 168 adults (50% male) were recruited from three districts: Nioro du Rip (n=90),
located in the Sudan Savannah agro-ecological zone where rainfall ...

Aflatoxins are a common contaminant of cereals that can cause cancer, liver disease, immune suppression, retarded growth and development, and death, depending on the level and duration of exposure. Maize is an introduced crop to Africa and there have been efforts over the last 20 years or so to r...
