Mycotoxins in Kenyan dairy cattle feed: occurrence and mitigation using bentonite and fumonisin esterase additives


PhD candidate: Kemboi, David Chebutia

David Chebutia Kemboi was born in Baringo, Kenya, on 31 March 1986. He finished his primary education in 1999 and secondary education in 2003. After high school, he joined the University of Nairobi for his Bachelor of Veterinary Medicine degree and graduated in 2010. Thereafter he enrolled for his Master of Science degree in Applied Microbiology at the same institution and graduated in 2014. In November 2014, he began working as an assistant lecturer at the Department of Animal Health and Production at Mount Kenya University. In 2015 he moved to the Department of Animal Science, Chuka University under the same capacity. In 2021, he was promoted to the position of Lecturer, a position he still holds to present. In September 2018, David started his PhD project (MycoSafe-South) at the Laboratory of Pharmacology and Toxicology of the Faculty of Veterinary Medicine at Ghent University, the Faculty of Veterinary Medicine at the University of Nairobi, and at the International Livestock Research Institute. The H2020 ERA-NET LEAP-Agri MycoSafe-South project aimed at reducing aflatoxins and fumonisins exposure in both animals and humans through post-harvest mitigation strategies, including the use of two mycotoxin detoxifiers. David’s doctoral thesis covers the dairy aspect that aims to reduce aflatoxin M1 (AFM1) contamination in the milk of two African dairy cattle breeds through the use of mycotoxin detoxifiers as feed additives. David Kemboi is main author of 5 scientific publications and co-author of 6 other publications, and he presented at several national and international conferences.

The dairy industry plays an integral role in the economy of most sub-Saharan African countries. Over the years the demand of milk and dairy products has increased leading to movement from pastoralism to intensive and semi-intensive systems. These intensive and semi-intensive systems rely on concentrates as a way of improving productivity. However, these concentrates have been shown to contain mycotoxins which are secondary toxic metabolites of fungi that affect animal health and productivity, as well as food safety.
