AFRICAN SWINE FEVER (ASF) ERADICATION CHANGE PROJECT IN SONGEA MUNICIPAL, RUVUMA REGION OF TANZANIA BY SERIA MASOLE SHONYELA 2018 DR.SERIA MASOLE SHONYELA Date i ACKNOWLEDGEMENT Although this is not the end of the project, I am thankful to God for giving me wisdom and direction to start doing this change project. Thanks to Swedish government as the international training was supported by the Swedish International Development Cooperation Agency (SIDA) through International Training Program (ITP) to be the initiative of the change project and for the training they provided for us. I am very grateful to the Songea Municipal livestock professionals for their collaboration in this project. Thank you doesn’t seem sufficient but it is said withappreciation and respect for your collaboration. My special thanks to the municipal director and head of livestock department for allowing me to use the office for meetings and to let the training happen. I owe a great deal of appreciation and gratitude to Dr. Erika Chenais For her good coordination on the training in Sweden, friendly environment to work with us on training period in Sweden I pay tribute to my mentor Magdalena Jacobson I warmly thank for her valuable advice and her extensive discussions when I was in Sweden for the training. I am also very grateful for her scientific advice and pig knowledge and many insightful suggestions. It’s my pleasure to acknowledge all teachers/instructors for their constant moral support, teaching and providing the good knowledge to carry out for disease control some part of myresearch work. I am much indebted to the chair person and assistant chairperson of the ITP program. I wish to thank our respectable brother in Sweden, for caring and guiding us during the training, Uweis Nassor I would also like to thank my colleagues from different countries in the region. The whole time of training was made happy, smooth, comfortable and easier with their presence and their questions. Last but not least, I would like to pay high regards to my three children, my mother, sisters, for their sincere inspiration and taking care of my children. ii TABLE OF CONTENTS ABSTRACT ..........................................................................

Disease transmission is maintained under different and complex epidemiological settings involving domestic and wild swine and arthropod vectors. Due to the fact that no vaccine has been obtained so far, prevention, control, and eradication of the disease is mainly based on the early detection and the implementation of strict sanitary measures. The disease is endemic in Sub-Saharan countries of Africa [2]. Since 1997, ASF was acknowledged in Tanzania, Kenya, Zambia, Mozambique, Malawi and many other African countries where the spreading is out of control, causing a serious threat to African countries [1]. African swine fever is since 2012 the most important threat to pigs in the Ruvuma region (official unpublished documented). ASF outbreaks have been continuing in the different districts in Ruvuma region, causing severe economic losses for many pig farmers and pork producers (slaughters/ butcheries; official unpublished documents). In addition, the number of ASF cases in Ruvuma region has dramatically increased over the past few years and is at the moment present in four districts. Evidence supports direct contact with infected pigs imported for slaughter that are kept in free- range management, and consumption of contaminated feed (i.e. uninspected pig offals and game meat), as the main transmission routes of ASF virus (ASFV) to domestic pigs. On the other hand, significant awareness gaps emphasize the vital need for research to investigate the importance of indirect transmission from the environment.This will provide an improved basis of knowledge on how to optimize current interventions and develop new strategies to reduce the risk of ASFV transmission to domestic pigs. 1 ASFV can be preserved in domestic pigs through a pig-to-tick cycle, which does not involve warthogs, and a pig-to-pig cycle through direct contact between infected and susceptible animals [3, 4]. Whilst the acute form of the disease is oftenseen in domestic pigs [5]. The importance of training and knowledge transfer of a devastating disease like ASF in domestic pigs has been recognized for many years since its first description in 1921 and was appreciated 1957 in Africa [6, 7]. Since acceptable circumstances concerning the control and prevention of ASF is not yet accomplished in Africa, there is still spread of the disease in many countries. In this situation, the Songea municipality is at high risk of introduction of the disease by legal or illegal movements of animals and animal products, particularly through imported pigs (abattoirs). In order to design a rational eradication model that takes into account different risk situations, knowledge about the pig farming systems / pork meat production and contact
