1. EFSA’s mission in relation to Bird Flu
4
EFSA’s Mission in relation to Bird Flu
  • Provision of scientific advice and scientific & technical support in all fields which have a direct or indirect impact on Food and Feed Safety to the EU Commission, MS, EU Parliament (following WTO and SPS Agreement)
  • Provision of independent information on all matters within these fields
  • Risk communication
  • Networking and collaboration

The 9 EFSA Scientific Panels
  • Panel on contaminants in the food chain
  • Panel on food additives, flavorings, processing aids and materials in contact with food
  • Panel on dietetic products, nutrition and allergies
  • Panel on biological hazards
  • Panel on additives and products or substances used in animal feed
  • Panel on genetically modified organisms
  • Panel on animal health and welfare
  • Panel on plant protection products and their residues
  • Panel on Plant health
7
BIOHAZ Panel mandate
  • deals with questions on biological hazards relating to food safety and food-borne diseases including food-borne zoonoses, transmissible spongiform encephalopathies, food microbiology, food hygiene and associated waste management

EFSA’s tasks on Bird Flu
  • January. 2004- AHAW -Statement on AI
  • September  2005- AHAW Scientific Report and Opinion on  animal health  and welfare aspects of AI
  • March 2006 –BIOHAZ -Scientific report on Food as a possible source of infection with HPAI viruses for humans and other mammals
  • May 2006 –AHAW-Report and Opinion on Migratory birds and their possible role in the spread of highly pathogenic AI-Asian lineage
  • November 2006.  AHAW- risks associated with the import of wild bird other than poultry into EU (exotic/petbirds)

DIVA Strategy
  • EU Policy was in favour of Stamping out:
    • not incentives for vaccination and DIVA strategy
  • Recent changing Policy:
    • in favour of vaccination (even OIE)
    • BUT there is a lack of tools
  • Vaccinated animals can not be exported according with OIE  Rules
    • disease notification and vaccination in a country means loss of money
    • Pilot projects: still less than 0.1% of the EU poultry are vaccinated

 “Food as a possible source of infection with highly pathogenic AI viruses for humans and other mammals”.
  • This scientific document analyses whether consuming food contaminated with HPAI (AI) virus could initiate infection in mammals via the digestive route.
  • Examinig existing data on AI, and H5N1 in particular, studying various aspects of the virus’s transmission in relation to food and the gastrointestinal tract.



20
Conclusions (I):
Food as a possible source of infection with HPAI viruses for humans and other mammals
  • There is no evidence that the virus replicates in the human intestine.
  • Even if virus uptake in the GI tract were possible, e.g. via nerve endings as was suggested in the experimentally inoculated cats, the chances that these endings would be hit are very slim.
  • Viral RNA or infectious virus may have been produced in throat or respiratory tissues and swallowed, or could have reached the intestine after generalisation from other infected targets.


21
Conclusions (II):
Food as a possible source of infection with HPAI viruses for humans and other mammals
  • Food that contains virus could be a source of infection if viral uptake were to occur via oropharingeal tissues. The existence of an undisclosed target cell in the intestinal tract cannot be ruled out.
  • Infection in humans occurs rarely and particularly after very close contact with infected animals. It is, likely that a high dose of virus may be needed to initiate an infection and that a readily accessible entry route for the virus does not exist.
  • Experimental studies on the exact route(s) of H5N1 virus entry in mammals are needed and may provide useful information for the human infection.

3. Future EFSA’s tasks on Bird Flu
  • December 2006. AHAW. Revision of the migratory birds opinion in the light of the last report of DG ENV : species involved and enlarging recommendations for surveillance.
  • January 2007. SCA. Epidemiological Analysis of the current outbreaks in the EU.
  • February 2007 AHAW Vaccination against avian influenza of H5 and H7 subtypes in birds kept in zoos
  • April 2007  AHAW. AI Vaccines on H5-H7 subtypes in domestic birds
  • 2007  BIOHAZ  continuously evaluating scientific evidence with respect to AI and food safety
  • 2007 AHAW   Update of the Risk assessment of AI in AH -overall assessment on the risk of the entry of H5N1 to the EU including latest findings and developments

4. Conclusions

4. Conclusions
  • Control of outbreaks of Asian lineage H5N1 HPAIv: worldwide top priority to reduce/avoid risks
  • Veterinary structure, control & BIP,  are critical points (awareness, diagnostic and quick measures)-Increase alert/surveillance systems (e.g. EU)
  • Trade live animals & commodities: main concern
  • Biosafety measures in all poultry productions systems . Migratory birds
  • Info Exchange between Vet-Medical services
  • RESEARCH and support to affected countries

EU/ DG RESEARCH FP7 projects on AI  2006
  • Aviflu 2002/6 (final)
    • to improve diagnosis and control, it proven that vaccination could be an effective approach to manage outbreaks;
  • Fluaid 2006/8 (cont. Aviflu)
    • Studies on vaccine application and DIVA test, to evaluate  the consequences of vaccination in terms of transmission and persistence;
  • EPIZONE 2006/11
    •  Network collaboration, 20 institutions, on epizootic infections, will cover diagnostics, intervention strategies, surveillance and epidemiology and risk assessment.
