This course will provide an overview of the microbiological hazards in various environments that may include water, soil, food, animals (including humans), the atmosphere and buildings. The students will work through some particular case studies of pathogenic microbial hazards. They will gain knowledge of how exposure to microbial agents occur and the adverse health effects that may eventuate. The course will develop the students' knowledge to determine the extent of exposure over a given period of time. An understanding of qualitative and quantitative risk assessment for predicting the probability of adverse health (response) following a particular exposure (dose) will be gained. The management, regulations and standards that set limits for exposures to microbiological hazards will be discussed. The students will obtain an introductory understanding of quantitative microbial risk assessment.
We are exposed to numerous biological hazards in our daily lives. Microbial hazards, in particular, are of great concern, due to the chances of exposure to an enormous variety of organisms through contaminated elements in our environment such asﾠ water or food.ﾠ One of the tasks of environmental and public health professionals is to assess and mitigate the risks of microbial transmission from the environment to humans. This course provides a comprehensive introduction to biological hazards in an environmental health context. A basic background in microbiology will be provided to facilitate the understanding of the growth, exposure and transmission mechanisms of biological hazards, and their impact on human health. Through case studies, we will explore various environmental exposure routes such as water, food, air, soil, fomites, as well as animal vectors. The course also provides an introduction to risk assessment and management using the quantitative microbial risk assessment framework, based on dose-response and exposure data. This course is relevant for students interested in environmental health from a biological hazards perspective, in particular microbial contamination acquired from environmental exposure.ﾠ

Aims and outcomes
This course will equip the students with a comprehensive understanding of the underpinning science associated with biological hazards in an environmental health context, covering a range of exposure routes such as water, food or vector-borne hazards.
At the end of the semester, students will be capable of formulating a biological risk problem, identifying the mechanisms underlying risk assessment, and critically evaluating source data. Students will learn how to identify the relevant exposure pathways in different scenarios, and use exposure data and health impact data to help quantify biological risk.
Students will acquire competencies in critically interpreting the results of microbial risk assessments and communicating these to a range of stakeholders, including appropriate recommendations for risk management.
