Eating undercooked, contaminated meat (especially pork, lamb, and venison)

是不是牛肉安全些？象trichinosis只在生猪肉里面有。而且，要真怕成那样，也不能养猫了。

Kittens and cats can shed millions of oocysts in their feces for as long as 3 weeks after infection. Mature cats are less likely to shed Toxoplasma if they have been previously infected. A Toxoplasma-infected cat that is shedding the parasite in its feces contaminates the litter box. If the cat is allowed outside, it can contaminate the soil or water in the environment as well.

People can accidentally swallow the oocyst form of the parasite. People can be infected by:

* Accidental ingestion of oocysts after cleaning a cat's litter box when the cat has shed Toxoplasma in its feces
* Accidental ingestion of oocysts after touching or ingesting anything that has come into contact with a cat's feces that contain Toxoplasma
* Accidental ingestion of oocysts in contaminated soil (e.g., not washing hands after gardening or eating unwashed fruits or vegetables from a garden)
* Drinking water contaminated with the Toxoplasma parasite

我觉得这病好像没什么了不得的，只要健康免疫系统没问题，没有太大危害。美国12岁以上的人口有22.5%感染率，不是说法国7/8成感染率吗？我看法国人美国人脑筋不正常的不见得比只吃熟肉的中国人多。：-）

不能惜命的都因噎废食吧？鸟为食亡，人要馋点儿也一样。：-）
