Abstract

Peanuts, cottonseed, rice, and sorghum from Texas were sampled over a 3-year period. To insure adequate isolation of alfatoxin-producing species of fungi, low-quality lots were sampled at a rate greater than their respective proportional representation. Aflatoxins were found each year in peanut and cottonseed and were found in 2 of 3 years in rice and sorghum. Aflatoxins were detected in all four crops. The Aspergillus flavus group was much more prevalent in peanut and rice than in cottonseed and sorghum. Of the isolates of the A. flavus group, 96% from peanuts, 79% from cottonseed, 49% from sorghum, and 35% from rice produced aflatoxins. The average toxin production of isolates from rice was much less than that from peanuts, cottonseed, or sorghum. More than 90% of all isolates of the A. flavus group were identified as the species A. flavus. A. parasiticus was isolated from all four crops. Only A. parasiticus produced aflatoxin G
