Mycotoxin toxicity depends on species, exposure time, age, sex, health and possible synergistic effects of other mycotoxins present in feed. In poultry, aflatoxin B1 (AFB1) and fumonisin B1 (FB1) are associated with poor growth performance, lowered feed utilization efficiency, liver damage and immunosuppression; metabolites may persist in tissues and eggs. Exposure of mature hens to zearalenone (ZEN) apparently does not cause adverse effects, but ZEN residues and α and β zearalenol persist in liver and muscle (Kuiper-Goodman et al., 1987) and may be transmitted to egg yolk (Dailey et al., 1990). Various treatments and dietary strategies have been tried to reduce mycotoxin levels in contaminated commodities...
