Abstract

In 1985, North Carolina and much of the southeastern United States were subjected to heavy late-season rainfall which resulted in a delayed harvest of the soybean crop. Upon harvest, it was discovered that there was widespread microbial damage in many lots of beans left standing in the fields longer than usual under high moisture conditions. Beans became moldy and some sprouted in the pods in the field (D.T. Bowman, personal communication). In the early winter of the same year, there were several reports of feed refusal and hyperestrogenism in swine in North Carolina, South Carolina, and Georgia (W.M. Hagler, Jr., unpublished observation). Much of the soybean meal in commerce was reported to be darker than usual, and analytical results from animal industry quality control and commercial laboratories indicated that many samples of soybean meal were contaminated with zearalenone (ZE) and possibly trichothecene mycotoxins (F.T. Jones, personal communication).
