1995年，加拿大不列颠哥伦比亚省的维多利亚发现了世界上第一次与市政供水有关的弓形虫病爆发。据推测，家猫（Felis卡图斯）或美洲狮（Felis concolor）的粪便污染了地表水水库与弓形虫卵囊，广泛的调查维多利亚流域1年后爆发记录存在一个地方性T，涉及该地区的动物居住的弓形虫周期。猫和美洲狮在整个流域都被观察到。血清学证据表明T.在生活在维多利亚地区的家猫中证实了弓形虫感染。美洲狮被发现脱落弓形虫卵囊。血清学证据表明T.生活在流域河岸环境中的鹿鼠弓形虫感染表明，T。刚地虫卵囊在水边脱落。维多利亚的供水被T.在研究期间可能发生了弓形虫卵囊，将来在这个社区和其他社区可能爆发水媒弓形虫病。
The world's first documented toxoplasmosis outbreak associated with a municipal water supply was recognized in 1995 in Victoria, British Columbia, Canada. It was hypothesized that domestic cat (Felis catus) or cougar (Felis concolor) faeces contaminated a surface water reservoir with Toxoplasma gondii oocysts, An extensive investigation of the Victoria watershed 1 year following the outbreak documented the presence of an endemic T, gondii cycle involving the animals inhabiting the area. Cats and cougars were observed throughout the watershed. Serological evidence of T. gondii infection was demonstrated among domestic cats living in the Victoria area. Cougars were found to shed T, gondii oocysts. Serological evidence of T. gondii infection in deer mice living in the riparian environments of the watershed suggested that T. gondii oocysts were being shed near the water edge. Contamination of Victoria's water supply with T. gondii oocysts potentially occurred during the study period and future waterborne toxoplasmosis outbreaks in this and other communities are possible.
