Regardless of the higher humidity at the Indiana site and the higher temperatures in Arkansas, aflatoxin was not detected in the grain after three-months of storage in either the PICS or woven bags. Sauer and Burroughs (1980) found that spread of A. flavus and aflatoxin accumulation was minimal at 16.5% maize moisture content, but growth and mycotoxin accumulation was extensive at 17.4%. A greater amount of rewetting occurred in the grain stored in the Indiana woven bags (2.9%), which resulted in a final moisture content (15.9%) that was below these minima for A. flavus and aflatoxin. We also observed a decrease of 75–80% in AFB1 in the satchels containing the A. flavus-contaminated maize. The reason for the decrease is unclear. The only example we found in the literature where aflatoxin contamination decreased was in field experiments conducted in North Carolina (Payne et al., 1988). The authors observed that aflatoxin contamination levels increased in A. flavus-infected kernels until maturity and then decreased during the dry-down period.
