I recently had to move in with an outdoor catfag as my only living option, and the vague stuff Wauf says about this shit had me terrified. Ended up doing some research into it, and wanted to share what I found and start an actual discussion without the hyperbole (if we can)
Firstly I want to distinguish toxoplasma gondii and latent toxoplasmosis; toxoplasma gondii is essentially food poisoning that only really affects pregnant women and is tied to infant mortality, head deformation, vision issues, mental disability and seizures. Latent toxoplasmosis is a long term parasitic infection caused by toxoplasma gondii. Whenever Wauf refers to 'T. gondii,' they actually mean latent toxoplasmosis.
Toxoplasma gondii starts it's life in a cat's stomach, the only animal it can breed in, as an oocyst which contains sporozoites. The oocyst ends up in the cat shit and can spread around, infecting by either being inhaled or digested.
I looked into it and the only effective common cleaner you can use to kill oocysts are ammonia; 10% at least. Sauce:
One ingested or inhaled the oocyst is shed releasing the sporozoites, which turn into tachyzoites. The tachyzoites turn into bradyzoites once they come into contact with the central nervous system, and the bradyzoites are the latent toxoplasmosis.
The only way to test for latent toxoplasmosis infection in humans is a serologic test for high immunoglobulin G (IgG), an antibody to T. gondii.
