| dc.description.abstract | Maize is the staple diet of majority of Kenyan population but repeated outbreaks of mycotoxin
poisoning in Eastern Kenya is a major food safety constraint. This study was conducted to determine
maize production and handling practices that contribute to aflatoxin contamination in maize in Eastern
Kenya. A survey was conducted in Makueni, Machakos, and Kitui Counties of Eastern province during
2008 and 2009 cropping seasons. Information gathered included agronomic practices, harvesting,
drying, transportation, storage materials and structures used, processing and weather conditions during
harvesting and storage. The survey revealed that such practices as planting of uncertified seeds,
harvesting maize before safe moisture content, drying grain on bare ground, storage in living houses and
use of synthetic (polypropylene) bags. Aflatoxin B

was detected in maize and maize products at levels
above the national legal limit of 10μg/kg. Such inappropriate handling practices in Eastern Kenya may
predispose maize to fungal and mycotoxin contamination. In addition, high temperatures and periodic
drought contribute to the higher fungal and aflatoxin contamination. Therefore, there is need for
continued mycotoxin awareness campaigns to educate farmers, traders, transporters and processors on
proper pre- and post-harvest handling practices to avoid contamination with aflatoxin. | en_US |
