Abstract

Mycotoxins affect nutritional and economic value of staple foods and cash crops especially in developing countries including Nigeria. Aflatoxin B1 when consumed by man or animal can cause liver cancer, reduced fertility, increased susceptibility to infections among other terrible diseases. In view of this a study was conducted to determine and compare the level and extent of aflatoxin B1 contamination of four different poultry feed ingredients namely maize, wheat offal, soya bean meal and groundnut cake obtained from 4 selected major feed mills ( A, B, C and D ) in Ijebu Ode, Ogun State of Nigeria. 500g samples of each ingredient were collected out of which 0.5g sample each in four replications of maize, wheat offal, soybean meal and groundnut cake were ran separately with 5g of sodium chloride (Nacl) weighed and poured in a blender jar to determine their aflatoxin B1 level. Aflatoxin B1 level was determined with ELISA (Enzyme Linked Immunosorbent Assay) reader at 450nm. The results obtained were analysed using statistical analysis software (SAS 1999) while the means were compared using Duncan multiple range test. The analysed result of aflatoxin ........................................................................................................
