Irrigation and pest management help reduce stress on plants that can leave them more vulnerable to Aspergillus growth and aflatoxin contamination.  Agricultural  techniques like crop rotation and appropriate harvest timing are helpful in this regard. It is important to assure proper pre-harvest drying and post-harvest sorting in a controlled environment.18  These are basic, low-cost interventions.  However, for subsistence farmers accustomed to existing cultural practices and with very little margin for error, adoption of some of these techniques represents a big change. Change should therefore be incremental, recognizing that even small steps to reduce aflatoxin exposure are important for public health.
