Ranajit Bandyopadhyay: Ending aflatoxin contamination in Africa

Developing countries lose billions of dollars in trade annually to aflatoxin contamination in foods. Worst still, the contamination endangers the health of millions of people in the region. But the good news is that IITA has developed a biocontrol product (aflasafe) to tackle this problem. Ranajit Bandyophadhay speaks to Godwin Atser on the journey that led to the development of aflasafe and other issues.

Tell us about your work at IITA
I am a plant pathologist, and one of my main responsibilities is how to manage plant disease. The other is to ensure food safety.

What about your work on biocontrol?
This is one the most exciting projects that I have ever had. The work on biocontrol is on a toxin found on maize and peanuts called aflatoxins. The toxin causes a lot of harm to people’s health and also makes farmers sell their products at lower prices. So, the losses are both in terms of health and trade. What I am trying to do is to manage the aflatoxins using a holistic approach, such as using resistant varieties, better crop management practices, and also the biological control method.

What is unique about your biocontrol work?
One thing that is unique is that we are using the natural resources from Nigeria to manage an economic and medical problem. We are making use of nontoxic fungi to eliminate the harmful fungi (aflatoxins).

Why are aflatoxins important?
Aflatoxins are harmful chemicals that are produced by a fungus called Aspergillus flavus.

The fungi produce toxins in maize, peanuts, and generally grains. When people eat them, it harms them and causes diseases such as liver cancer and kwashiorkor, among others. Worst still, farmers cannot sell their products at the premium price.

What makes you keen about biocontrol?
It is one of the strongest components of the holistic approach. If we can have the biocontrol approach adopted by farmers, most of the problems concerning aflatoxins which they face during postharvest will be greatly reduced.

Do you see IITA in the position to offer the biocontrol option to farmers?
Absolutely yes. The reason is that we actually started with good science and that science has given birth to a new product which the farmers are willing to use.

Tell us about this product
The product is “aflasafe”. We coined the name aflasafe; when farmers use the product on their farms, they would produce grains that are free from aflatoxins.

Did you face any challenge in developing the product?
The first challenge was developing the product itself. The fresh challenge now is how to get a large manufacturing firm to begin massive production, advocacy, and awareness so that it gets to the farmers.

Any interest so far?
We made a presentation to the Minister of Health, Prof. Babatunde Osotimehin, and he was so excited about the product. We also did a field deployment and the farmers were also very happy about it.

Who were your partners in this work?
Many organizations and people were involved in this work. They include the AATF, National Agency for Food and Drug Administration and Control, farmers, United States Department of Agriculture, US Agency for International Development, Prof Peter Cotty, Dr Joseph Atehnkeng, and several others.

How were you able to handle these partners?
Every partner is a unique entity but one thing important is to build trust. Once that is done, the partnership gets smooth.

Research wise, what are you future plans?
My future plan is to get this product used on at least one million hectares. I intend to put all my efforts to see that this product is used for the benefit of the farmers in general and women and children who are more vulnerable to aflatoxins.
