The most common sources of infection in people are: 

     1.  Eating raw or undercooked meat - especially port of lamb.
     2.  Exposure to oocysts(the prasite's "eggs") in contaminated soil.
     3.  Exposure to oocysts in cat feces.

There is a blood test to determine whether or not a person or animal has been exposed to this parasite.  However, test results in cats can have many different meanings.  In people, there appears to be little risk to the fetus in mothers who are "seropositive"(previously exposed and antibodies are present) prior to pregnancy.  You should discuss the details with your physician.  The issue of testing in cats is a controversial one and routine testing is not typically recommended.  Further questions on testing your cat can be answered by one of our veterinarians.

Preventing infection is the key to safety regardless of blood testing results.
To reduce exposure in cats:

     1.  Confine cats inside to prevent hunting.
     2.  Feed cats only commercially prepareddiets(no raw meat or raw milk).
     3.  Have the litter box changed daily by a non-pregnant household member.  Do not spread used cat litter in yard or garden.

To reduce exposure in people:

     1.  Eat only thoroughly cooked meat - specially pork and lamb.
     2.  Wash hands and utensils thoroughly after handling meat or cats, as well as, after gardening(use gloves if possible).
     3.  Prevent cats from defacating in children's sandboxes by keeping them covered when not in use.
     4.  Do not drink raw milk, especially goats milk.

Following these guidelines should help prevent exposure to Toxoplasmosis and assure a pregnancy free from this organism.
