E. coli is a very serious threat to human health. It can be devastating and sometimes fatal, and children and elderly people are at particular risk. We still know little about how it is spread in rural environments. Researchers from a wide range of natural and social science disciplines investigate how we can reduce the risk of people becoming infected.

E. coli O157 risk assessment
E.coli O157 incidence in Grampian and Wales, assessed from human cases of the disease (from data collected from Foresterhill hospital and Health Protection Wales) and from the general population (derived from Scottish and English/Welsh census data). Data for Grampian are presented as number of cases, population and incidence (/100,000 people) at postcode district level for the period 1997-2008.

Best-worst scaling of interventions
Expert opinion on the effectiveness and practicality of environmental interventions to reduce human exposure to Escherichia coli O157. The intervention list was compiled from published research and an initial expert consultation was undertaken to reduce the set of 99 interventions to a more manageable list of 30 interventions. Then experts selected the most and least effective measures from 12 sets of 5 interventions, followed by selecting the most and least practical measure in each set.
