Predicting aflatoxin content in peanuts using ambient temperature, soil temperature and soil moisture content during pod development

Higher than acceptable aflatoxin levels in peanut kernels (Arachis hypogaea L.) and related products is a worldwide food safety concern. Strict regulatory standards by major importers of peanuts limit the marketability of peanuts for many developing tropical countries including Zambia. The incidence of pre-harvest aflatoxins is strongly linked to soil and weather conditions during pod-development. This study aimed to...
