Distribution of aflatoxigenic Aspergillus section Flavi in commercial poultry feed in Nigeria por Ezekiel, C.N., Atehnkeng, J., Odebode, A.C., Bandyopadhyay, Ranajit

“…The population ofA. flavus in the feed had positive (r= 0.50) but non significant (p N 0.05) correlations with proportion of toxigenicisolates obtained fromthe feedwhile SBG had significant (p b 0.001) positive (r= 0.99)influence on AFB1 concentrationsin the feed. Poultry feed in Nigerian markets are therefore highly contaminated with aflatoxigenicAspergillus species and consequently, aflatoxins. …”
