Who is lookingfor information? • Private actors are interested in information on disease outbreaks for: Preventing disease transmission (feed companies, input retailers, large scale farmers) Anticipating price variation and planning the activities in accordance (feed companies, input retailers, large scale farmers) Purchasing poultry at low price (poultry traders) • Public surveillance is considered a useless source of information. Private actors rely on informal surveillance. Results

- 21. Conclusions 1. Innovative approach •Actors of surveillance = decision makers facing socio-economic constraints • Interest of combining economic evaluation tools and participatory approach 2. Key elements to enhance the compliance to surveillance and control programs : • Producers and actors of input supply chain mainly aim at mitigating impact of epizootics on their income and on market prices • Existence of a private surveillance centered on feed companies • Poor sanitary controls on the poultry value chain have an impact on disease surveillance • Institutional impediments = need for better control and higher support from the central administration : encourage local actors to notify diseases
