What causes toxoplasmosis?
Toxoplasmosis can result from:
- Accidentally swallowing Toxoplasma gondii eggs from soil or other contaminated surfaces. This can happen by putting your hands to your mouth after gardening, cleaning a cat's litter box, or touching anything that has come into contact with cat feces.
- Eating raw or partly cooked meat, especially pork, lamb, or venison, or touching your hands to your mouth after touching the meat.
If you are pregnant when first infected with Toxoplasma gondii, you can give the infection to your baby.
You may also receive it through an organ transplantation or a transfusion, although this is rare.
