“…For all four epidemics, the following interventions were carried out by the Regional Veterinary Services in the areas involved in the epidemics : monitoring of flocks at risk of infection, stamping out or controlled marketing of all birds on IFs, ban or controlled restocking and movement restrictions for live birds, vehicles and staff [15,16].…”

“…The differing levels of adoption by different household poultry producers have implications for the overall breach in biosecurity with the consequent risks of infection in the household. Low frequencies of adoption of a comprehensive biosecurity package have been confirmed in previous studies to contribute significantly to disease outbreaks on farms (Bos et al, 2007;East, 2007;Kung et al, 2007;McQuiston et al, 2005;Thomas et al, 2005;Dorea et al, 2010;Fasina et al, 2011The adoption of certain measures however indicated that given the right atmosphere, the household producers were willing to improve their management and disease control practices.…”

Increased animal intensification presents with increasing risks of animal diseases. The Egyptian household poultry is peculiar in its management style and housing and this present with particular challenges of risk of infection to both the flock and humans. Biosecurity remains one of the most important means of reducing risks of infection in the household poultry, however not much information is available to support its feasibility at the household level of production. In this study financial feasibilities of biosecurity were modeled and evaluated based on certain production parameters. Risks of particular importance to the household poultry were categorized and highly pathogenic avian influenza H5N1 was the most risky disease while people-related risk was the most important risk category. It was observed that basic biosecurity measures were applicable in the household poultry and it would be 8.45 times better to implement biosecurity than to do nothing against HPAI H5N1; 4.88 times better against Newcastle disease and 1.49 times better against coccidiosis.Sensitivity analyses proved that the household poultry project was robust and would withstand various uncertainties. An uptake pathway for basic biosecurity was suggested. The outcome of this work should support decisions to implement biosecurity at the household sector of poultry production.

“…Poultry farmers should consider carcass disposal techniques that do not require off-farm movement, such as burial, composting and incineration, because of the highly infectious nature of AI virus and the devastating economic impact of outbreaks [3]. In an outbreak of HPAI, in-farm or near-farm disposal is basically required.…”

ABSTRACT. Establishment of a disposal plan for carcasses in advance is important for prevention of epidemics. A disposal plan for contaminated goods such as poultry carcasses infected with highly pathogenic avian influenza (HPAI) virus was studied in Hyogo Prefecture, Japan. We investigated all poultry farms with over 1,000 birds for their locations, species and numbers of birds, structure and size of poultry facilities and land spaces of the farms. Moreover, we judged whether they could dispose of all the carcasses at their farms. In 2005, 5.5 million layers and 2.7 million broilers were being kept. If HPAI had broken out, 44.0% of the farmers could bury all the carcasses, and 65.6% could compost them at their farms. However, 23.4% could not dispose of them except by burning them at incineration facilities. We decided to choose burning first for rapid disposal as long as the virus was not a pandemic type.KEY WORDS: avian disease, epidemiology, influenza.
