Seasonal agricultural changes can impact rural households’ diets and income, affecting their long-term health and welfare. Changes in diet quality are of particular concern, as diets lower in nutritional diversity have been shown to increase the risk of chronic undernutrition, micronutrient deficiency, and cancer and cardiovascular disease.

Aflatoxin, a toxin produced by the Aspergillus fungus, poses a serious health threat in developing countries. The toxin grows in a number of staple crops worldwide, such as maize, and chronic exposure can lead to liver disease, cancer, and even death. While proper testing and processing of crops can reduce aflatoxin levels in finished food products like maize flour, many developing countries lack the regulatory environment needed to enforce such testing and handling requirements.

New labeling system may bring safe, affordable maize flour to Kenyan consumers

Kenyan consumers are demanding maize flour that is safe from contamination by aflatoxin, a chemical linked to cancer and other health problems. The toxin, produced by certain fungi, is commonly found in maize from several regions of Kenya due to a combination of environmental conditions and poor post-harvest practices.

In the past, discussions about food security have typically focused on the quantity of food that people eat rather than the quality .  However, micronutrient deficiencies are becoming increasingly recognized as a serious threat to the health and economic development of low-income populations. As a result, nutrition is garnering more and more attention in the development community.
