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.

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.

Airport traffic flow and signage review

An international airport authority sought a comprehensive assessment of passenger and vehicle traffic flow after receiving complaints of confusion and safety concerns. Reports indicated that passengers were struggling to interpret signage, often stopping too long to process graphics, which caused line-ups and delays. Lighting problems compounded the issue, with signs placed in poorly illuminated areas.…

Methodology for Developing Risk Significance Insights

The project centered on supporting the development of a methodology that could eventually be implemented as an Artificial Intelligence (AI) or Machine Learning (ML) process. The objective was to help formalize and potentially automate how professional judgment is applied when determining the risk significance of non-compliant findings within the Canadian nuclear regulatory framework. Specifically, the…

Finalization of Risk Assessment on Secure Opioid Dispensing Devices

To support decision-making around modifications to opioid agonist treatment delivery, a detailed risk assessment was requested to evaluate the integration of secure dispensing devices for direct patient access to hydromorphone. Building on a previously conducted preliminary assessment, the work required a structured framework that would articulate hazards, assess likelihoods and risks, and identify mitigation strategies associated with introducing these devices into service delivery models.

Pickering Nuclear Facility Re‑licensing

The client sought support to finalize a Commission Member Document (CMD) for the re‑licensing of a nuclear facility. Recognizing the complexity and sensitivity of reactor re‑licensing, they requested assistance in crafting communication materials that were both technically comprehensive and accessible to regulatory bodies and broader audiences. The work included drafting a clear and well‑structured CMD,…

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.

Environmental Health Factors, Chronic Diseases, and Pandemic Resilience

To support more effective health policy and pandemic preparedness, this project examined how environmental health factors intersect with chronic disease and influence pandemic resilience. The client sought evidence to clarify how exposures to contaminants in air, water, and soil contribute to the environmental burden of disease in Canada and exacerbate vulnerability to infectious disease outcomes, including COVID-19.
