Study areaThailand Vietnam
8
First results – investigations ongoing • Law and regulation
– There are many organization associated with SH but Department of
Livestock Development (DLD) is the main responsible organization to
control the slaughterhouse in Thailand
– Slaughterhouse Act has been used since 1992
– The Standard Slaughterhouse Regulation has been strictly used since
the outbreak of avian influenza
– All of small scale slaughterhouses do not meet the standard regulation
9
First results – Capacity Thailand = 30-50 birds/day Vietnam = 20-30 birds/day
10
• Socio-economics
– Average monthly income of SH owner is 34,500 Baht (1,150 USD)
– Average monthly expenses of SH owner is 24,000 Baht ( 800 USD)
35% (28/80) had to stop running business compared with last 2
years , mainly because the owners could not follow the DLD
regulation and unstable economics
First results – investigations ongoing
11
• Public health
– Improper hygienic management is common practices
– Majority of consumers did not realize the important of food
safety (eg. price more concern than quality )
• Environmental impact
– Majority of SH release the waste water to environment without
treatment
– Salmonella spp. were found in waste water, soil around the SH
First results – investigations ongoing
12
Summary of Biosecurity• Cleaning and disinfection
– Thailand : 75% clean the SH daily– Vietnam : 85% clean the SH daily
• Source of water – Thailand: 28% use underground water– Vietnam : 80% use underground water
• Officer visit – Thailand: 50% had officers visit 4-6 times/year– Vietnam: 75% had officers visit 1-2 times/year

SOME TYPICAL IMAGES OF RESEARCH ACTIVITIES
19
Planned activities for 2012 and beyond
• Finalising of remaining sampling (Feb 2012 –THAI)
• Joined analysis of field and laboratory data will be performed
tentatively in Jan-Feb 2012 (Thailand-Vietnam)(Mid term
workshop)
• Jointly identify policy recommendation
20
Planned activities for 2012 and beyond
• Possible Pilot trials for interventions
– Select the pilot slaughterhouses and apply/implement
identified interventions (prototype SH)
– (next project, new phases, funds pending)
21
Expected outputs and outcomes
• Output
– Recommendation of the hygienic practices in the small
scale poultry slaughter houses
• Outcome– Systemic approaches for sustainably improving the
hygienic status of slaughterhouses – Development of suitable hygienic practices in the small
scale poultry slaughterhouses
22
Perspectives
• The project is ongoing, the further development is still
monitored
• The collaboration among the stakeholders are expected to be
the results from Ecohealth approach
• The small scale poultry slaughterhouses should not be closed
because of the regulation
