African swine fever (ASF) is a highly fatal infectious disease of domestic and wild pigs of all breeds and ages with no effective vaccine or treatment. The incursion of ASF into Asia and the Pacific region has been a major concern as the region is the major pig production area, which produces over 58 percent of pigs globally (FAOSTAT). The concerns, therefore, are growing for its impacts on food security and economics as the virus is expanding towards more areas and countries in the region. As the disease continues to expand into new territories, preparedness and control activities need to be constantly adjusted to adapt to situations observed in the field that may be contrary to what was expected based on international standards or experiences from other parts of the world. National veterinary services face challenges in these complex situations, and so regional and international support is needed to fill capacity gaps required for ASF control and to facilitate dialogue among key stakeholders. Through various regional and national consultation meetings, affected countries have requested technical support to make available relevant technical guidelines for ASF control that are practical especially for smallholder pig farmers in the context of Asia (SO5). This Farm biosecurity, slaughtering and restocking] is the third of the series of the “Guidelines for African swine fever (ASF) prevention and control in smallholder pig farming in Asia” which guides biosecurity, slaughtering and restocking practice in smallholder pig farming system which are designed for use by national and/or central veterinary authorities, farmers and relevant stakeholders, especially focusing on Southeast Asian pig industry.

This [Culling and disposal of pigs in an ASF outbreak] is the second of the series of the “Guidelines for African swine fever (ASF) prevention and control in smallholder pig farming in Asia” which provides guidance on planning and conducting pig culling and disposal operations in smallholder setting including other relevant actions, such as cleaning and disinfection of premises in the event of an ASF outbreak.

African swine fever (ASF) is a highly fatal infectious disease of domestic and wild pigs with no effective vaccine or treatment. The incursion of ASF into Asia and the Pacific region has been a major concern as the region is the major pig production area, which produces over 58 percent of pigs globally (FAOSTAT). The impact of ASF on economies and food security is increasingly worrying. As the disease continues to expand into new territories, preparedness and control activities need to be constantly adjusted to adapt to situations observed in the field that may be contrary to what was expected based on international standards or experiences from other parts of the world. Through various regional and national consultation meetings, affected countries have requested technical relevant technical guidelines for ASF control that are practical especially for smallholder pig farmers in the context of Asia (SO5). This volume is the fourth of the series of the “Guidelines for African swine fever (ASF) prevention and control in smallholder pig farming in Asia” which outlines the principles of an ASF clean-chain system for smallholder pig producers in Southeast Asia. It provides recommendations on the practical application of good biosecurity management practices combined with traceability in smallholder pig systems necessary for the continued production and supply of commodities along the pork value chain irrespective of the prevailing ASF virus risk situation.

This document aims to provide guidance for government officials in: Defining surveillance objectives Establishing ASF-related case definition and reporting criteria Providing examples of potential ASF surveillance methods Identifying various crucial factors in consideration of a surveillance system Evaluating a surveillance system Since its incursion to Asia and the Pacific region, African swine fever (ASF) has shown impacts on food security and economics as the virus is expanding towards more areas and countries in the region. As the disease continues to expand into new territories, preparedness and control activities need to be constantly adjusted to adapt to situations observed in the field that may be contrary to what was expected based on international standards or experiences from other parts of the world. This surveillance guideline provides guidance for government officials in defining surveillance objectives, establishing ASF-related case definitions and reporting criteria, providing examples of potential ASF surveillance methods, identifying various crucial factors in consideration of a surveillance system, and evaluating a surveillance system.

African swine fever (ASF) is endemic in some parts of eastern and southern Africa. The introduction of ASF into free areas leads to losses because of the devastating effects it causes. In order to minimize these losses, it is essential that there is a strong early warning and early reaction capacity. The key to such a system is disease recognition. The purpose of this manual is to enhance recognition of ASF at all levels for early warning and early reaction, so that the disease can be identified and eliminated at its earliest appearance in any area. Special attention has been given to the clinical, anatomical and pathological similarity of African swine fever with classical swine fever.
