Aflatoxin-producing members of Aspergillus are common and widespread in nature. They can colonize and contaminate grain before harvest or during storage. Host crops, which include maize, sorghum, and groundnuts, are particularly susceptible to infection by Aspergillus following prolonged exposure to a high-humidity environment, or damage from stressful conditions such as drought. In 2003, 120 people died in Kenya after eating maize with very high aflatoxin levels.[6]
