a
Experimental rats were fed ground moldy wheat-complete diet (1:1), and control rats were fed an autoclaved wheat-complete diet (1:1). Three rats were used for each treatment.
b
—, no detectable toxic effect. Abbreviations indicate toxic effects (congestion [C], excess mucus production [M], hemorrhage [H], and degeneration [D]) in various organs (intestine [I], stomach [S], and bladder [B]).
c
Toxins were quantified by TLC.
