Cassava is an important food crop for millions of people in sub-Saharan Africa, but unfortunately this crop is facing a decline in production across the continent due to Cassava Mosaic Disease (CMD). I came to the BecA-ILRI Hub in August to work on a project funded by the National Science Foundation Partnerships for International Research and Education (NSF-PIRE) to analyze the evolution of the viruses that cause this disease.

The purpose of this project is to understand how African cassava mosaic virus (ACMV) and East African cassava mosaic virus (EACMV), the causal agents of CMD, evolve during vegetative propagation of infected cassava plants versus being transmitted via whiteflies. It is our goal to understand how these viruses evolve in order to develop strategies that will hinder the development of more virulent strains and thus prevent future outbreaks of CMD.

When I first arrived in Kenya, I travelled to the shores of Lake Victoria in the western part of Kenya to collect whiteflies for the establishment of a colony at the BecA-ILRI Hub. This was a good opportunity to interact with local farmers and see the devastating effects that this disease has on cassava production in Kenya. Once the individual whiteflies were collected we set up a room dedicated to establishing a colony to be used in future experiments.

Because multiple species of whiteflies exist, my colleagues and I have focused our efforts on understanding the genetic make up of the colony to ensure that we have a single species for our experiments. Additionally, we established procedures for the propagation and growth of cassava in the greenhouse. We continue to lay the groundwork for pilot experiments that will act as the basis for our future work.

I am excited to be a part of this project and the BecA-ILRI Hub community. I am grateful for everyone’s support and input and look forward to great discoveries in the future.

A vision for safe, affordable and adequate food – Kenya Cereal Millers Association collaborates with BecA-ILRI Hub to combat aflatoxin contamination http://localhost/becahub/blog/a-vision-for-safe-affordable-and-adequate-food-kenya-cereal-millers-association-collaborates-with-beca-ilri-hub-to-combat-aflatoxin-contamination/ http://localhost/becahub/blog/a-vision-for-safe-affordable-and-adequate-food-kenya-cereal-millers-association-collaborates-with-beca-ilri-hub-to-combat-aflatoxin-contamination/#comments Thu, 09 Jun 2016 10:29:47 +0000 BecA-ILRI Hub Communications http://hub.africabiosciences.org/blog/?p=577 By Paloma Fernandes, CEO of the Kenya Cereal Millers Association

PalomaHaving a milling capacity of 1.6 million tonnes of maize per year and constituting 85 percent of the commercial flour on the shelves sold to about 10 million consumers annually, the Cereal Millers Association (CMA) bears the heavy responsibility of providing safe, affordable and adequate food for their consumers. This responsibility is at the heart of our vision as an association which comprises 27 of the largest millers in the country.

Our four-year relationship with the BecA-ILRI Hub’s aflatoxin research project was borne out of our quest to bridge the existing gap in best practices for diagnosis of aflatoxins at the millers’ level. In efforts to find a solution, we participated in various national forums on the control of aflatoxins in the food value chain in Kenya and eventually made the connection with the project.

Through our collaboration with the BecA-ILRI Hub, CMA staff members have received training on the proper use of aflatoxin diagnostics equipment to get the most accurate results.Visits by the BecA-ILRI Hub scientists, research technicians and project collaborators to three CMA mills has helped us ascertain the levels of testing, training needs and ways in which we can improve our storage, transport and testing facilities.

In order for us to take adequate measures in providing safe food for Kenyans, we have extended
our collaboration to exploratory research on the types of aflatoxins we are dealing with at our mills and will provide samples of both wheat and maize to the BecA-ILRI Hub for analysis.

Through this partnership, we have also identified a consultant from Texas A&M University, USA, to
develop and test the feasibility of maize sampling and aflatoxin testing protocols for use in Kenyan maize mills – an initiative in which many of our mills are involved.

The dream of CMA is to have a fully-fledged laboratory for testing of aflatoxins and we believe with the support of research institutions like the BecA-ILRI Hub, this dream is not very distant. Ultimately we hope that we can achieve our goal to provide safe, affordable and adequate food for all our consumers.
