Storage structures and aflatoxin content of maize in five agroeclogical zones of Nigeria.

A survey was conducted in 1994 to describe the maize storage systems, quanitfy the aflatoxin levels in these storage systems, and identify the main problems of maize storage recognized by both men and women farmers in 5 agroecological zones in Nigeria. Maize storage in bags wasthe most common among all farmers. The clay rhumbu was used in 4 out of 5 agroecological zones and the woven oba was found only in the southern guinea savannah and was used predominantly by women. Farmers who reported insect problems were significantly more likely to have aflatoxin in their stores. The highest zonal mean aflatoxin level of 125.6 ug/kg was obtained from maize samples provided by male farmers in the Sudan savanna zone who stored maize in bags or in a rhumbu. Across the  storage systems, 33% were contaminated with detecable levels of aflatoxin. No aflatoxin was detected in the storage systems in the northern Gunea savannah zone in 1994.
