Cassava mosaic disease (CMD) caused by African cassava mosaic virus (ACMV) and East African cassava mosaic Cameroon virus (EACMCV) is the major constraint to cassava production in Nigeria. Sequences of the DNA-A component of ACMV and EACMCV isolates from leguminous plant species (Senna occidental...
Aflatoxin is a potent mycotoxin that can cause cancer, stunted growth, and (in extreme instances) rapid death. Aflatoxin can contaminate many staple crops, including maize and groundnuts. As many as 4.5 billion people in the developing world may be chronically exposed. Scientists at the United St...

Cassava(Manihot esculenta), a root crop originating in Tropical America, has been called Africa’s food insurance but vital as that is, it has the potential to be much more. Already, cassava provides more than half of the dietary calories for over 200 million people in sub-Saharan Africa (about ha...

Aflatoxin M1 (AF M1), a hydroxylated metabolite of AF B1, is an important toxin that can contaminate themilk of lactating mothers. A correlation study was conducted to determine the relationship between AFM1 content of breast milk, dietary exposure to AF B1 and socioeconomic status of lactating m...

Aflatoxins are highly toxic metabolites of several Aspergillus species widely distributed throughout the environment. These toxins have adverse effects on humans and livestock at a few micrograms per kilogram (μg/kg) concentrations. Strict regulations on the concentrations of aflatoxins allowed i...

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...

In Nigeria, Aflasafe is a registered biological product for reducing aflatoxin infestation of crops from the field to storage, making the crops safer for consumption. The important questions are whether farmers will purchase and apply this product to reduce aflatoxin contamination of crops, and i...
