Environmental contamination with parasite eggs poses a serious risk to public health. This study aimed to assess the presence of taeniid eggs and, in particular, E. granulosus s.l., in environmental samples in the city of Ibadan, South West Nigeria. To this purpose, soil (n = 200), fecal (n = 200) and water samples (n = 50) were examined by microscopic observation and the multiplex PCR method. The influence of specific environmental factors on E. granulosus s.l. egg dispersion was also evaluated. Taeniid eggs were microscopically found in 11.5%, 25.5% and 8.0% of soil, fecal and water samples, respectively. PCR analyses evidenced the presence of E. granulosus s.l. in 8.0%, 24.0% and 2.0% of soil, fecal and water samples, respectively. The proximity to slaughterhouses, the level of urbanisation and the local government area of belonging did not seem to affect E. granulosus s.l. egg dissemination patterns. Our results have clearly demonstrated that both urban and semi-urban areas of the city of Ibadan in Nigeria are highly contaminated by taeniid eggs and we recommend the adoption of appropriate measures to control E. granulosus s.l.
