Contamination of crops by aflatoxin is rampant in warm regions worldwide, including Sub-Sahara Africa. Contamination of maize and other foodstuffs with aflatoxin seriously threatens the health of humans and animals. The experimental design used was 2 × 2 × 3 factorial, laid out in a complete randomized design (CRD) consisting of two agroecological zones, two varieties, and three different packaging materials. At the end of the six months of storage, there was no contamination of the maize with aflatoxin G1. Again, there was no contamination of maize stored in the Forest zone with aflatoxin B1. High contamination levels of aflatoxin B1 (8.91 μg/kg), aflatoxin B2 (10.74 μg/kg), and aflatoxin G2 (14.49 μg/kg) occurred in the Wangdataa variety stored in jute. Purdue Improved Crop Storage (PICS) bags recorded lower contamination levels than jute and polypropylene (PP). Contamination was higher in the Savannah zone than in the Forest zone. The three packaging materials used gave maximum protection to all the maize stored in the Forest against aflatoxin B1 and aflatoxin G1. Farmers, traders, and all aggregators of maize in the Savannah zone should be discouraged from using jute bags to store maize in the Savannah zone for an extended period. Opeaburo should be planted and stored in the Savannah zone rather than Wangdataa. Farmers should be encouraged to use PICS bags to store maize in the Savannah zone to control aflatoxin B1, aflatoxin B2, and aflatoxin G2. |
