Some Disease Control Strategies
Used in Animal Disease Outbreak
•
Destruction (‘stamping-out’)
• CO2, electrocution, others
• ensure ‘humane’ culling
• Movement control /Quarantine
•
Disposal
•landfill, incineration,
composting, rendering
•easier to arrange once
emergency powers invoked
• Cleaning & Disinfection
◦ manure, structure
Human Health Protection
OSH considerations

Health screening (suitability)
Information/Training

Personal Hygiene
Health surveillance / reporting / ff-up
Prophylactic meds / vaccination

Health surveillance / CD control
Need for
increasing collaboration
between
CFIA and its partners
Increasing Challenges for CFIA
•
•
•
•
•
•
•
global distribution (food, livestock, pets, feed, seeds)
intensive farming /new technologies
changes in consumption and eating patterns
consumer expectations/practices
effects of global warming (insect vectors; ecology)
speed and scope of international travel
increasing susceptibility of large segments of the
population (e.g. compromised immunity; allergies)
• public demand for transparency and involvement
Emergence of Foodborne Pathogens

What is the nature of the disease?
What is the nature of the pathogen?
Simple ways to easily identify the pathogen and
diagnose the disease?
What is the incidence of the infection?
How can the disease be treated?
Which foods transmit the infection?
How pathogen gets into the food, and how well it
persists there?
Is there an animal reservoir?
How do the animals themselves become infected?
How can the disease be prevented?
Does the prevention strategy work?

Guidelines for
Research on Zoonoses




Identify the source of infection, to determine
whether it is from wildlife, domestic or peridomestic animals, or from multiple sources;
Establish the mode of transmission, to determine
whether it is by direct contact, vectorborne,
environmental contamination, or a combination of
modes;
Identify potential host species and the natural
reservoirs of the zoonotic pathogen, possibly with
molecular and/or epidemiological methods;
Conduct preliminary surveys of target species and
follow-up, when indicated, with long-term
ecological and epidemiological studies of identified
reservoir species in the wild and/or in an
experimental setting where appropriate.
