An Outbreak of Cysticercus ovis in Nova Scotia.

In 1980 and 1981, Cysticercus ovis infestations were found in lambs at slaughter from four geographically separated farms in Nova Scotia. Epidemiological investigations showed that a common factor was the presence of dogs which came from or had been trained on a fifth farm. It was subsequently shown that sheep on this latter farm were also infested.Not allowing dogs access to raw mutton, offal and sheep carcasses and the regular treatment of dogs for tapeworms controlled the outbreaks on the four farms.
