Senior Research Fellow
Project Background 

Food-borne microorganisms are major pathogens affecting food safety and cause human illness worldwide because of the consumption of foodstuff, mainly animal products contaminated with vegetative pathogens or their toxins. Most of these microbes have zoonotic importance resulting in a significant impact on both public health and economic sectors. Bacteria are the causative agents of two-thirds of human food-borne diseases worldwide with high burden in developing countries. The main objective of our research activities on Food and water safety is to determine the bacteriological quality of food (both cooked and raw) and water meant for human consumption as well as the presence of zoonotic bacteria pathogens and antimicrobial residues in food originating from animal origin. These studies determine the bacteria load and identify (zoonotic)pathogens to determine whether they are within the limits acceptable by the Food and drugs authority (FDA). Weconductbacteriological analysis of food and water for producers/companies and advice on strategies to maintain standards of production.
