Determination of aflatoxin levels in Sudanese edible oils.

Fifty-six samples of groundnut, sesame and cottonseed oils form factories, and traditional mills were collected from several localities in Kordofan, Gezira and Khartoum states, Sudan and assessed for aflatoxin B(1) (AFB(1)), aflatoxin B(2) (AFB(2)), aflatoxin G(1) (AFG(1)) and aflatoxin G(2) (AFG(2)), using high performance liquid chromatography (HPLC). Aflatoxin B(1) (AFB(1)) was detected in eight samples representing 14.3%, the highest incidence of aflatoxin contamination occurred in sesame (7 out of 16 samples, 43.
