<jats:title>Abstract</jats:title><jats:p>The sub‐Alpine lakes of Switzerland, Italy and France have long been reported as an endemic area of diphyllobothriosis, a parasitic zoonosis caused by <jats:italic>Dibothriocephalus latus</jats:italic>. With this study, we explored the hypothesis for a relationship between the prevalence of <jats:italic>D. latus</jats:italic> in <jats:italic>Perca fluviatilis</jats:italic> and the <jats:italic>Escherichia coli</jats:italic> load in lake water. To do this, we identified eleven sampling sites in three areas (north, centre and south) of Lake Iseo (north Italy) to determine <jats:italic>E. coli</jats:italic> load and the prevalence of <jats:italic>D. latus</jats:italic> in <jats:italic>P. fluviatilis</jats:italic>. Prevalence and 95% confidence interval (CI) of <jats:italic>D. latus</jats:italic> infestation ranged from 0% (95% CI: 0.71–0.0) in Sarnico (southern area) to 20% (95% CI: 33.0–11.2) in Pisogne (northern area). There were significant differences in prevalence between the sites (χ<jats:sup>2</jats:sup> = 31.12; <jats:italic>p</jats:italic>‐value = .0006) and in <jats:italic>E. coli</jats:italic> load (Kruskal–Wallis test; <jats:italic>p</jats:italic>‐value = .0005). There was decreasing gradient of <jats:italic>E. coli</jats:italic> load and prevalence of <jats:italic>D. latus</jats:italic> infestation from north to south. A significant positive correlation (<jats:italic>r</jats:italic> = .881; <jats:italic>p‐</jats:italic>value = .003) was found between <jats:italic>E. coli</jats:italic> load and prevalence of <jats:italic>D. latus</jats:italic>. Also, linear regression showed a significant relationship between <jats:italic>E. coli</jats:italic> load and prevalence of infestation (<jats:italic>R</jats:italic><jats:sup>2</jats:sup> = .775). Our findings offer an explanation for the link between <jats:italic>E. coli</jats:italic> load in water and <jats:italic>D. latus</jats:italic> prevalence. The potential factors in this link are the efficiency of the local wastewater treatment plant, the bathymetric profile of the lake and the life cycle of <jats:italic>D. latus</jats:italic>, which is mainly affected by light and water temperature.</jats:p>
