Abstract
Feed samples from Iowa suspected of causing vomiting and enlarged vulva as well as mortalities of swine were examined for toxigenic fungi and mycotoxins Fusarium moniliforme Sheldon and F. moniliforme Sheldon var. subglutinans Wollenew. & Reink. accounted for 43% and 18.5%, respectively, of the total count of 4.75×105 propagules filamentous fungi per gram of swine feed, but representatives of various Penicillium spp. and Aspergillus spp. were also found. Eight isolates of F. moniliforme var. subglutinans from the feed produced 51–540 μg of moniliformin per g on cracked corn at 25°C for six weeks. Zearalenone was not detected in these corn fermentations. Eight isolates of F. moniliforme from the feed did not produce detectable amounts of either zearalenone or monoliformin on cracked corn. Moniliformin was not detected in the feed samples.
