Subchronic Feeding Study of the Mycotoxin Fumonisin B1 in B6C3F1 Mice and Fischer 344 Rats. Voss, K. A., Chamberlain, W. J., Bacon, C. W., Herbert, R. A., Walters, D. B., and Norred, W. P. (1995). Fundam. Appl. Toxicol.24, 102-110. Fumonisin B1 (FB1) is a mycotoxin produced by Fusarium moniliforme, a common fungus which occurs naturally on corn, and other Fusarium species. FB1 and other fumonisins are now recognized as having potentially important animal and human health implications. However, few toxicological data are currently available. Male and female B6C3F1 mice and Fischer 344 rats were fed diets containing 0, 1, 3, 9, 27, or 81 ppm FB1 (⩾98% purity) for 13 weeks. No differences in behavior or appearance, body weight or food consumption between control and FB1-fed groups were found. In mice, hepatopathy and altered serum chemical profiles indicative of hepatotoxicity were found in females fed the 81 ppm diet. No adverse effects were found in female mice fed ⩽27 ppm FB1 or in male mice at any dietary level studied. In rats, nephrosis involving the outer medulla was found in males fed ⩾9 ppm and, to a lesser degree, in females fed 81 ppm FB1, while decreased kidney weight was found in both sexes at dietary levels ⩾9 ppm FB1. Although the liver is a target organ of FB1 in rats, hepatotoxicity was not found in rats fed diets containing up to 81 ppm FB1 for 90 days. Thus, FB1 was toxic to both species following subchronic oral exposure, although significant interspecies differences in the no observed effect levels and organ-specific responses were found.
