چکیده انگلیسی

While the value of geographic information systems (GIS) is widely applied in public health there have been comparatively few examples of applications that extend to the assessment of risks in food distribution systems. GIS can provide decision makers with strong computing platforms for spatial data management, integration, analysis, querying and visualization. The present report addresses some spatio-analyses in a complex food distribution system and defines influence areas as travel time zones generated through road network analysis on a national scale rather than on a community scale. In addition, a dynamic risk index is defined to translate a contamination event into a public health risk as time progresses. More specifically, in this research, GIS is used to map the Canadian produce distribution system, analyze accessibility to contaminated product by consumers, and estimate the level of risk associated with a contamination event over time, as illustrated in a scenario.


► Use of GIS to conduct spatio-temporal analyses in a food distribution system.
► Use of GIS to conduct a food spatial accessibility analysis on a national scale.
► Use of GIS to analyze the consumer accessibility to contaminated food product.
► Use of GIS to illustrate public health risk associated with a contamination event.
