Interpretive Summary:

Technical Abstract: Five strains of Fusarium moniliforme and two strains F. proliferatum of the section Liseola were each fermented on rice for 21 days at 25 deg C. All but one of the dried, fermented rice materials, when mixed into a poultry diet (10% by wt), caused various degrees of acute mortality in baby Pekin ducklings. The acute (less than 48 hr) mortality significantly correlated only to the amount of moniliformin in the diet but not to the amount of fumonisin B1. This correlation with moniliformin concentration and non-correlation with fumonisin B1 concentration was confirmed by duckling assay using diets containing purified mycotoxins. These results suggest that the mycotoxin fumonisin may not be of practical concern to the poultry industry. Moniliformin may be a concern, but naturally occurring levels have not been reported for U.S. corn crops.
