    Preparation of African swine fever contingency plans 2009
    African swine fever (ASF) is a viral haemorrhagic disease of swine generally characterized by high morbidity and high mortality. The disease is known to have devastated swine farming in highly industrialized, small commercial and backyard swine holdings, with concomitant closure of animal and meat export markets, ravaged swine populations, and destroyed individual and family livelihoods. ASF is one of the more difficult transboundary animal diseases to control as no successful vaccine has yet be en developed; it is transmitted by direct contact between infective and susceptible swine, and by infected soft ticks of the Ornithodoros genus; and it has several wildlife reservoirs in areas where it is endemic. The ASF virus can last for long periods in contaminated environments or cured pork products, which can be a source of infection or introduction of the disease to distant areas.The disease, present in most of sub-Saharan Africa, made its way to Europe in the late 1950s, where campaigns for its eradication on the mainland took more than 30 years to conclude. In the 1970s and 1980s, the disease was introduced several times into a few countries in the Americas, with eventual elimination only after national and international concerted action. In mid-2005 ASF was first reported in the Caucasus and spread within the region, causing concern to swine producers in Eastern Europe and beyond.This manual is based on the manual on ASF (FAO Animal Health Manual No. 11) published in 2001, updated to capture new knowledge and adapted to cover European settings.

    A risk assessment for the introduction of African swine fever into the Federated States of Micronesia 2022
    Also available in:
    No results found.

    This report describes a risk assessment mission in the Federated States of Micronesia, undertaken by the EpiCentre, School of Veterinary Sciences, Massey University, and the Food and Agriculture Organization of the United Nations (FAO) under FAO Technical Cooperation Programme (TCP/SAP/3801). The overall aim was to evaluate the risk of introducing the African swine fever virus (ASFV) into the Federated States of Micronesia and use the findings to propose recommendations that enable professionals, communities and key stakeholders to implement prevention and mitigation measures to reduce the impacts of African swine fever (ASF) incursion. ASF is a highly contagious viral disease of domestic and wild pigs. It has emerged from Africa, spreading to eastern Europe, China and Southeast Asia. Due to ASF outbreaks in Asia and Papua New Guinea, Pacific Islands countries now prioritise preventing the introduction of ASF. A risk assessment of ASFV introduction is necessary for deciding which preventive actions would be most effective. The assessment of risk was conducted using the OIE import risk analysis framework. The most likely pathway for introducing ASFV into the Federated States of Micronesia was importing unauthorised pork products that international arrival passengers may bring in via airport or searport. Should infected products enter the Federated States of Micronesia, there is a distinct pathway for exposure because pigs are routinely fed food scraps (swill) from households. The likelihood of transmission of ASFV to other susceptible pigs was considered extremely high due to the lack of farm biosecurity and the presence of feral pigs. The assessment method was a systematic, qualitative import risk analysis of ASFV introduction to the Federated States of Micronesia. Results provide information about high-risk areas for ASF introduction, exposure and spread in FSM. They also identify gaps in control and prevention measures. The following steps are being proposed to minimise the likelihood of entry and exposure and the consequence of ASFV introduction.
