Aflatoxin was detected in 30% of 1,283 truckloads of Commodity Credit Corporation white corn (1971) delivered to a designated elevator from 77 loans in seven counties in southeastern Missouri (detection limit 1-3 ppb). Only 14% of the truckloads of corn contained more than 20 ppb aflatoxin. The toxin was not detected in any corn delivered from 20 of the farmers' loans. The geometric means of aflatoxin levels in corn from seven loans were higher than 20 ppb. Very few truckloads of corn contained aflatoxin G-1. Based on geometric means of aflatoxin level of loans, toxin content was related to grade although with a low correlation coefficient of 0.29 for aflatoxin B-1 and 0.27 for B-2.
