Food Safety Auth. Network) WHO Networks Lab-based surveillance Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 4

7 Disease burden from Diarrhoea Disease Incidence Food- and Waterborne approximately 4,000,000,000 cases per year Deaths approximately 1,800,000 per year (below five mortality) Remember Significant numbers of other foodborne diseases (caused by both microorganisms and chemical substances) Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 7

8 Deliberate contamination of Food recent concern but old problem The recognition of the source and potential intention behind an outbreak or contamination event will in many cases only be possible at a very late stage Although deliberate contamination presents a special set of issues, the same detection and response systems need to tackle outbreaks or contamination events whether the event is intentional or unintentional It is important to maintain that prevention needs to be part of any coherent food safety system covering both intentional and unintentional events Intentional Outbreaks, Accidental Outbreaks and Sporadic Cases all part of the disease burden and often difficult to separate reinforcing the need to use one emergency system Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 8

9 Deliberate contamination of Food one global market Contamination events will not be prevented through border control Early detection will most likely not be achieved through border control New and more efficient - food safety systems try to focus on preventative efforts as close to the source as possible (e.g. HACCP) Many food contamination events have international implications Capacity to prevent and detect need to be build in all countries reinforcing the need to use an international system Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 9

10 Food Safety Emergency Preparedness Strengthening food safety systems through -Prevention -Surveillance, preparedness & response Foodborne Outbreaks Large number of casualties intentional or accidental: accidental outbreaks up to 300,000 patients Economic disruption : a product, a manufacturer, an industry or a country. Fear : consumers, public. Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 10

11 WHO Alert & Response E P I D E M I C A L E R T & R E S P O N S E I N T E R N A T I O N A L H E A L T H R E G U L A T I O N S Contain known risks Respond to the unexpected Improve preparedness G L O B A L P A R T N E R S H I P Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 11

12 NEW (and better) International Health Regulations (IHR) Old IHR only covered Yellow Fever, Cholera and Plague New IHR proposes the extension of the WHO coordinated public health emergency system to include all public health emergencies of international concern - including foodborne emergencies New IHR will enter into force May 2007 No need for national ratification All WHO Member States will be obliged to declare public health emergencies of international concern to WHO Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 12

13 What is needed for food emergencies? International system to minimize impact on public health and food trade by: Detecting an international incident rapidly Rapidly responding to international emergency Deciding on when the emergency situation is over System requires: Rapid communication Capacity to verify and make decisions Procedures to respond and capacity to assist National preparedness capacity with international links Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 13

14 In cooperation with FAO Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 14

15 INFOSAN Information sharing on any food safety issues INFOSAN Emergency Food safety alert and response One Contact Point/country Many Focal Points from govt agencies Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 15

16 INFOSAN International Food Safety Authorities Network Linking all national food safety authorities (150 countries now members) Providing information and assistance to Member States Enhancing interaction between food safety authorities Enabling information on national needs to WHO and FAO Supporting reorientation of strategic directions Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 16

17 INFOSAN International Food Safety Authorities Network INFOSAN Focal point in Agriculture Sector INFOSAN Focal point in Health Sector INFOSAN Focal point in Food Safety Authority INFOSAN Focal point in Trade Sector INFOSAN Focal point in other Sectors Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 17

18 INFOSAN Emergency Part of INFOSAN (150 Member States) A network of designated contact points for international food safety emergencies Working to retrieve information on incidents with international importance Working towards spreading international alert information, when needed Supporting the definition of national alert and response systems Supporting exchange of outbreak experience from Member States, including specific prevention and response advice Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 18

19 WHO Global Outbreak Alert & Response International Health Regulations (IHR) INFOSAN Emergency Network National Outbreak Alert & Response System National INFOSAN Emergency Contact Point Rapid intelligence, e.g. poison control centres Foodborne disease surveillance & investigation Communications Linkages Recall & tracing systems Food import/export inspection Food control laboratories Industry alert systems Food contaminant monitoring Other systems Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 19

20 INFOSAN DEVELOPMENT Reaching out to all Food Safety Authorities Guided by the participants Looking for partners Developing Operating Procedures and training for National Contact Points Experience sharing Response and Prevention Drills to test system Defining network, national focal and contact points Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 20

21 INFOSAN DEVELOPMENT Examples of Emergency Action July 2005 Salmonella in Powdered infant formula from France to 13 countries Most countries reported that they received official info from INFOSAN only August 2005 Salmonella in unpasteurized orange juice USA to 4 countries Most countries reported that they received official info from INFOSAN only Streptococcus suis in pork No international action upon advice from Emergency Contact Point September 2005 E. coli O157 in lettuce No international action upon advice from Emergency Contact Point Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 21

23 WHO Global Salm-Surv a network building capacity for laboratory-based surveillance for salmonellosis and other foodborne diseases Surveillance of foodborne diseases provides information for action. The use of laboratory data in surveillance enables the identification of pathogens and the potential sources of infection. Integrated surveillance including human data as well as animal- and foodmonitoring data allows preventive action along the entire food-chain. In 2000 WHO initiated the WHO Global Salm-Surv (GSS) network to build laboratory and epidemiological capacity for integrated laboratorybased foodborne disease surveillance. The network now has almost 900 members from 141 countries. Department of Food Safety, Zoonoses and Foodborne Diseases, World Health Organization 23
