Systematic Review of Artificial Sweeteners and Health Risks

A comprehensive systematic review was undertaken to assess experimental evidence regarding the potential health risks associated with artificial sweeteners, specifically focusing on cancer and pre-term delivery. The client sought a rigorous analysis of both in vivo and in vitro experimental studies to better understand any biological associations or mechanisms that might underpin observed health outcomes.

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,…

External Peer Consultation of the Inorganic – Late Biomonitoring Approach Draft Screening Assessment Report

To support the Chemicals Management Plan under the Canadian Environmental Protection Act (CEPA), Health Canada sought expert peer consultation for a draft screening assessment report (DSAR) evaluating 47 inorganic substances identified as priorities. The client required independent scientific and technical expertise to assess whether the report’s conclusions—particularly regarding health effects, exposure pathways, and risk characterizations—were sound, complete, and defensible.

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…

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) Compliance and Enforcement

Innovation, Science and Economic Development Canada (ISED), through its Spectrum Management Innovation Directorate, sought support in applying risk-based decision making (RBDM) across its compliance and enforcement responsibilities. The department was looking for a structured and data-driven approach to prioritize regulatory actions in a way that reflects risks to the public interest.

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.
