One Health:A Critical Pathway to Ensuring Global Food Safety Marguerite Pappaioanou, DVM, PhD CDC Liaison to FDA for Food Safety The findings and conclusions in this presentation are those of the author and do not necessarily represent the views of the Centers for Disease Control and Prevention or the Food and Drug Administration
Several Current Complex Health Problems • Feeding 7 billion people (and growing numbers) with nutritious, accessible, affordable food • Impacts of climate change • Floods, droughts • Changes in reservoir hosts, vectors of disease • Natural and human-made disasters • Urbanization; Land Use and Agricultural Practice Changes • Access to clean air and drinking water • Non-communicable diseases • Poverty • Biodiversity • Risk of emerging infectious diseases, pandemics
Why One Health? • Health problems today are complex; caused by multiple drivers, factors • No single discipline or sector can do it alone • Opportunities for prevention, mitigation along a continuum– multiple sectors and disciplines essential to solutions
One Health Is the Collaborative Effort of Multiple Disciplines – working locally, nationally, and globally– to attain optimal health for people, animals, and our environment. AVMA-AMA One Health Task Force
Implementing One Health • Policies • Impacting on drivers, process, outcome, impact; resource allocation, communications • Multisectoral /disciplinary health programs • Providers/treatment/care • Disease prevention, surveillance, response, control, treatment • Multisectoral/disciplinary Research • Multi/Inter Professional Education
Why Implement One-Health ? • Achieve improved health for humans, animals, and the environment– all interconnected-- more effectively and efficiently • More efficient use of limited resources • Cost effectiveness of infrastructure to carry out prevention • Achieve overall good for nation, region, world

Food Security • Exists “when all people at all times have access to sufficient, safe, nutritious food to maintain a healthy and active life”. • Includes both physical and economic access to food that meets people's dietary needs and food preferences. • Three pillars: • Food availability: sufficient quantities of food available consistently. • Food access: having sufficient resources to obtain appropriate foods for a nutritious diet. • Food use: appropriate use based on knowledge of basic nutrition and care, as well as adequate water and sanitation.
Globalization of the Food Supply Global Poultry Exports Air Routes
Imported Foods and Entry Lines to the US • Imported food entry lines has doubled • 4.4 M in 2002 • 8.6 M in 2010 • As of 2011, ~ 15% of all food products consumed in the US were imported • 20% of fresh vegetables • 50% of fresh fruit • 80% of seafood
Food Safety • Assurance that food will not cause harm to the consumer when it is prepared and/or eaten according to its intended use (WHO). • Causes of illness– contamination of food with bacteria, viruses, parasites toxins, metals, prions • Symptoms range from mild to severe and life threatening • Range of food related activities with respect to foodborne illness -- from prevention and surveillance to detection and control
Ensuring Food Safety and Defense • Surveillance • Detection • Assessing magnitude of the problem • Outbreak investigation • Response/mitigation • Prevention • Regulatory Systems • Capacity Building
Estimates of Burden of Foodborne Illness(Morbidity, Mortality, Economic Costs2011 Estimates) • Canada (32.5 M people) • 1 in 8 Canadians (4 Million people) domestically acquired/yr • Cost ~ $12-14 B annually • The United States (300 M people) • 1 in 6 Americans (48 M people) with foodborne illness • ~ 128,000 hospitalized • ~3,000 people die • Cost ~ $77.7 B (individual costs) annually • Globally (WHO) (7 B people) • 1/3 of global population (2 billion people) • 1.5 billion cases of diarrhea in children < 5 yrs/year, • > 3 M premature deaths Scallan, et al, EID 2011; Thomas et al, Foodborne pathogens and disease 2013
International Costs of Foodborne Illness • Loss of trade (commodities– produce, livestock, etc.) • Loss of food • Loss of tourism • Public Health Surveillance costs • Outbreak investigations • Clean-up
Global Food System – “Farm to Fork” • Food production systems to feed growing human population at affordable cost (produce, nuts, meat, aquaculture, processed foods) • Land, Water, Climate change • Animal feed, fertilizers, pesticides, antibiotics? • Markets – local, national, international, role of small holders, women • Livestock housing, animal welfare considerations • Genetics, genomics, seeds, animal and plant health, emerging food pathogens • Transportation: To Processers, Distributers, Retailers, Food Stores, Marketing • Agricultural investments • Economic crises, Rising Food Prices, Political turmoil and unrest • Supply chain risks
How contamination of foods occurs • Fields fertilized with untreated manure, watered with unclean water • Animals fed contaminated feed • Many bacteria– i.e., Salmonella spp., Campylobacter spp., Yersinia enterocolitica, E. coli STEC, can reside in healthy food animals showing no signs of illness. • These animals can spread the bacteria to other healthy animals on the farm and during transportation to processing facilities • During processing, the bacteria may cross-contaminate other foods being processed at the same location. • Food is stored at too high a temperature and for too long • Many different countries supply foods to other countries. • Consumers should also be alert to the potential for cross-contamination in the home.
Challenges for Food Safety Authorities • Increasing burden of foodborne illness and new emerging foodborne hazards (healthy animals) • Rapidly changing technologies in food production, processing and marketing • Developing science-based food control systems with a focus on consumer protection • International food trade and need for harmonization of food safety and quality standards • Changes in lifestyles, including rapid urbanization • Growing consumer awareness of food safety and quality issues and increasing demand for better information Source: Assuring Food Safety and Quality: Guidelines for strengthening national food control systems. FAO/WHO Publication
Food Safety Challenges of Developing Countries • Differ by region-- differences in income level, diets, local conditions, and government infrastructures. • Food producer and the consumer often have a close connection. • Fewer processed and packaged foods • Most fresh food is traded in traditional markets; street vendors supply much of the food consumed outside the home. • Perishable food often prepared and consumed immediately • Minimal storage of prepared foods.
Food Safety Concerns - Developing Countries • Inappropriate use of agricultural chemicals • Use of untreated or partially treated wastewater • Use of sewage or animal manure on crops • Absence of food inspection, including meat inspection • Lack of infrastructure, such as adequate refrigeration • Poor hygiene, including a lack of clean water supplies
