Measuring impact of zoonotic animal diseases in Canada

A large number of domestic and foreign animal diseases with zoonotic health impacts to humans must be managed carefully to prevent disease transmission and spread. Risk management decisions often involve the comparison of different types of risk and the cost-effectiveness of different control measures for reducing risk. This requires that different types of risk be assessed in a consistent manner to allow cross-comparisons. The use of disability adjusted life years (DALYs) as a measure of the burden of human disease from domestic and foreign animal pathogens was completed for several zoonoses in Canada.

Environmental Public Health Approach (EPHA) to Chemicals Expert Workshop

To advance the Government of Canada’s Chemicals Management Plan (CMP), a virtual expert workshop was planned and hosted to refine and evaluate a Canadian framework for the Environmental Public Health Approach (EPHA) to chemicals. The initiative focused on developing case study models that could serve as a foundation for more comprehensive assessments linking chemical exposures…

Applying New Assessment Methods (NAMs) for Assessing Semi-Volatile Organic Compounds (SVOCs) in Indoor Residential Environments

Health Canada sought expert support in advancing its efforts to develop screening values for semi-volatile organic compounds (SVOCs) commonly found in residential indoor environments. Previous work on indoor air contaminants had focused on volatile organic compounds (VOCs), where screening values were developed based on existing inhalation quantitative hazard assessments (QHAs). However, many SVOCs were identified as having insufficient data to establish such values, leaving critical gaps in risk evaluation.

Risk-Based Decision-Making (RBDM) Support for Plasma Supply / Sufficiency

Facing renewed challenges in securing a reliable domestic plasma supply, Canadian Blood Services sought support to apply a Risk-Based Decision-Making (RBDM) framework. The objective was to assess the value and implications of expanding domestic plasma collection and processing capacity in response to the emergence of commercial plasma operations that export plasma to international markets.

Risk Communication on McIntyre Powder

In response to increasing public concern about the historical use of McIntyre Powder—an aluminum-based substance once administered to miners in Ontario to prevent silicosis—the client sought expert guidance on managing risk communication related to potential health implications. Widespread media coverage and advocacy had raised public awareness and intensified scrutiny, particularly about possible links between aluminum exposure and long-term respiratory and neurological conditions.

Technical Support for Risk-Based Decision Making (RBDM)

To enhance the oversight of cannabis production under its regulatory mandate, the Cannabis Directorate sought expert support in developing a risk-based decision-making framework tailored to its compliance and enforcement responsibilities. The directorate aimed to better assess and respond to non-conformance with Good Production Practices (GPP) as defined in the Cannabis Act and Regulations, using a data-driven approach.

Risk Model Framework for Foodborne Campylobacteriosis via Poultry Meat Pathway

To support national public health goals, RSI was tasked with developing a quantitative microbiological risk assessment (QMRA) model to estimate the human health risks associated with the consumption of chicken in New Zealand. The core objective was to quantify the relationship between Campylobacter contamination on poultry carcasses at the point of chilling and the subsequent incidence of foodborne illness among consumers.

EFSA Framework for Problem Formulation

To enhance the methodological rigour of its scientific assessments, EFSA sought to develop a standardised framework for problem formulation (PF) within its non-application scientific assessment protocols. The goal was to support the planning phase of these assessments by establishing a structured, reproducible approach for translating mandates into scientifically answerable questions. This included creating a framework…

Age-Related Cognitive Decline: Systematic Review and Meta-Analysis

The College of Physicians & Surgeons of Alberta (CPSA) commissioned a systematic review and meta-analysis to support evidence-informed decision-making around age-related cognitive decline among practicing physicians. The initiative was led by CPSA’s Physician Health Monitoring Program (PHMP), which sought to ensure continued competence and public safety in the context of an aging medical workforce.

Risk Assessment of the Impact of Lethality Standards on Salmonellosis from Ready-to-Eat (RTE) Meat and Poultry Products

To support regulatory decision-making, a comprehensive risk assessment was conducted to evaluate how varying lethality performance standards would impact the public health burden of salmonellosis associated with Ready-to-Eat (RTE) meat and poultry products. The primary objective was to quantify the expected number of cases of illness under different reductions in Salmonella presence across a broad spectrum of RTE product categories.
