What is AfricaAIMS
� One-stop information portal on aflatoxins– Aflatoxin prevalence data
– Production and trade data
– Relevant health data
– Information resources and training materials
� Fill in gap in locally-relevant, home-grown data� Fill in gap in harmonized data collection� Facilitate mapping of hotspots and support prediction
models for aflatoxin contamination patterns� Eventually inform policies and regulations, facilitate
local and cross-border trade, and improve consumer health
Steps in AfricaAIMS
1. Selection of partner institutions and signing of Memorandum of Agreement (AUC-Host)
2. Sampling and testing protocol (consistent across countries)
3. Selection of target crops4. Capacity buildling: Provision of VICAM fluorimeter
and consumables; training of laboratory personnel5. Data collection: sampling and testing; health and
trade data6. Refresher training on ARIS 2 interface7. Data upload on AfricaAIMS portal through ARIS 28. Data analysis and summarization9. Developing database [next phase]
Partner Institutions
� Chitedze Agricultural Research Station (CARS), Malawi� Plant Protection Directorate (DPV), Senegal� Nelson Mandela-African Institution of Science and
Technology (NM-AIST), Tanzania� Department of Food Technology and Human Nutrition,
Makerere University, Uganda� National Agricultural Research Institute (NARI), The
Gambia� National Agricultural Quarantine Services (NAQS),
Nigeria
� Kenya Agricultural and Livestock Research Organization (KALRO), Katumani, Kenya
Selection of Target Crops
� Groundnut and maize in Malawi
� Groundnut, maize and rice in Gambia
� Groundnut, maize and rice in Senegal
� Groundnut, maize and rice in Tanzania
� Groundnut, maize and sorghum in Uganda
Sampling and Testing Protocols� Sampling involved taking 5–10 incremental
portions from each crop lot to make up the 1kg composite sample.
� Samples were taken using a sampling probe or scoop
� Sampling at farm gate, household stores and markets
� Samples transported in sterile paper bags from the sampling point to the AfricaAIMS host laboratories and stored at 4oC until analysis.
� Analysis was done using VICAM fluorimeter(LOD: <3ppb) with immunoaffinity column clean up

Conclusion� First phase of AfricaAIMS data generated in
2015/2016 from four of six PACA pilot countries has shown that key staples, groundnut and maize, consumed across Africa are highly contaminated with aflatoxins.
� Indication that sorting of infected and damaged kernels or cobs lowers toxin levels during storage, while poor storage conditions and practices were important factors (e.g. notably sorghum in Uganda).
� Urgent need to improve storage conditions. � Good agricultural practices and adoption of novel
control technologies that span pre-harvest to post-harvest to lower toxin contamination in field and along the value chain.
