You have a higher risk of getting it from gardenign or eating undercooked meat. Also, in regards to the litter box, the oocysts need 24 hours to sporulate and become infective, so even if YOU scoop it morning and night you would be OK. (not saying don't have DH do it anyhow, LOL)
In terms of YOU being tested, I'm a vet and have worked in the field for roughly 20 years and I got tested with my 1st 2 kids and was negative. I didn't bother getting tested this time around. If you test the cat, be careful what kind of test he's getting-tests that test for antibodies only tell you whether or not he has been exposed in the past to the organism-not whether he is currently infected and possibly shedding toxo. Two tests a few weeks apart that showed an increase in the antibody levels would indicate an active infection which would be more concern for shedding.
I can honestly tell you I don't worry about it-not saying YOU shouldn't, just that I don't and I have a much higher "risk" of being infected than the average person. If you follow the previously mentioned hygiene and care recommendations, you should be fine!
