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.

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


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.
Food Security
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 Supply and Globalization
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

2011 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)



~ 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

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 crosscontamination 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

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
