India, Dec. 31 -- The overall level of contamination of cassava by various types of fungus is very high across Africa, ranging from 85 per cent to 95 per cent, with an average contamination rate of about 90 per cent, according to a new study.

Clear differences were observed between regions, according to the study. In West Africa (Nigeria, Ghana, and Benin) contamination rates were consistently above 90 per cent. This high level is largely linked to poor drying practices, which allow molds to grow and produce mycotoxins.

In East Africa, particularly in Uganda and Kenya, contamination levels were also high, with an average rate of about 88 per cent. The warm and humid climate in these areas creates favourable conditions for fungi such as ...
