Summary:
Scientists from the University of Bonn and the IITA in Nigeria, want to combat the highly toxic mould Aspergillus flavus by an unusual method: they 'inoculate' the fields with a variant of aspergillus which cannot produce any toxin in the hope that the 'good' mould will displace the 'bad'. They are being supported in this by US researchers from Arizona, who by using this method have been able to reduce the aflatoxin contamination of cotton by 98 per cent.

In the early 1960s more than 100,000 turkeys died in Britain of cancer of the liver. Eventually, researchers identified mouldy peanut flour from Brazil containing large amounts of aflatoxin as the cause of this mysterious 'turkey X' disease. Even today the toxin is regarded as one of the most virulent natural carcinogenic substances.
