6. Two phases of aflatoxin contamination
Before crop maturity
Developing crops become infected
Associated with crop damage (insect, bird, stress)
Favoured by high temperature (night) and dry conditions
After crop maturity
Contamination is increased;
By rain during harvest
By drying on soil
By poor handling during harvest, transport and storage
By storage if humid, warm, insect infested
Food is vulnerable until consumed!
8. • Harmonized standards in foods and feeds
• Enhanced capacity of regulators
• Standard protocols for sampling and quantification
• Alternative uses (treat with ammonia and feed to cattle)
• Inclusion in nutrition and health policies
• Critical role of PACA and RECs
