Public Warnings • Issued for most Class I recalls • May be issued for other classes • Reserved for those situations deemed to be of higher risk to consumers • examples: undeclared allergens, botulism risk, Salmonella, E.coli 0157, pieces of glass in baby food * Web-site posting and e-mail distribution list
- Animal Health - Public Health related activities • control and eradication of • traditional zoonotic diseases(TB, brucella, rabies) • new and emerging diseases(WNV; AI … SARS?) • therapeutant residue • mitigating/monitoring (A-M, H, …) • policy/management of • animal health issues (within federal mandate) • recycling of agricultural byproducts through • feed and fertilizers into the food chain • environmental concerns (disposal, …)
- Animal Health -Prevention of Foreign Animal Diseases • Surveillance • passive(producers, priv.vets, F/P labs, vet. colleges, PH) • active(sentinel systems, pro-active testing) • Reporting of Notifiable Animal Diseases • International (OIE, PROMED AHEAD) • Domestic (Health of Animals Act) • Risk Analysis (importation) • Import Controls • On-Farm Biosecurity(& traceability) * Can.

Avian Influenza Outbreak BC Coast – 2004
Animal Epidemiology Unit • Monitor changes in infectious/toxic agents • Define a problem/Detect outbreaks • Estimate magnitude of the problem • Determine geographic distribution of illness • Generate hypotheses • Stimulate research • Describe the natural history of a disease • Evaluate effectiveness of control measures • Detect effect of changes in practices • Facilitate planning/risk-based priority-setting

Avian Influenza in BCEpidemiologic Investigation Routes of virus transmission? • Tools • veterinary visit & questionnaire • follow-up on movements of risk products (eggs, …) • Transmission routes investigated … • waterborne (ground and surface water) • feed • hatcheries • wild birds • CFIA crews • litter • aerosol dispersion • service providers (owners, workers, equipment …)
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 • Protective clothing • Personal Hygiene • Health surveillance / reporting / ff-up • Prophylactic meds / vaccination PH considerations • Exposure / bio-security issues • Health surveillance / CD control
Need for increasing collaborationbetweenCFIA 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

When new foodborne disease identified • 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? Tauxe R., Emerging Foodborne Diseases: An Evolving PH Challenge, CDC 1997
Guidelines for Research on Zoonoses • Identify the source of infection, to determine whether it is from wildlife, domestic or peri-domestic 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. from Report on WHO/FAO/OIE consultation May 2004
