toxoplasmosis worry!

Hi there. I wonder if anyone can alleviate my worries so I can bond with our lovely new kitten?!
We adopted grace from a rescue organisation she's 4-5 months old and was picked up as a stray. Having welcomed her home I've read allsorts about toxoplasmosis that has concerned me as we have a 5 year old daughter.
Does anyone know the likelihood of her having toxoplasmosis from hunting or is she too young? And if she had congenital toxoplasmosis would she have gone through the shedding phase soon after birth? Wearer really careful about litter changing and had washing etc. If grace did have toxoplasmosis would the infectious time pass within a few weeks anyway...hopefully I can relax a bit then and really enjoy her. She'll probably be an indoor cat. Thankyou in anticipation, a paranoid new cat owner!!

Basically, the article says cats only shed oocytes a few days for their entire life making the risk of transmission small.

It is possible that she could have it because cats can contract it by walking through infected wasted and then cleaning their paws. But even if she does have it, it's not likely that you or your family have anything to worry about. Just hanging out with your cat poses basically no risk of contracting it. Handling waste is the only source of contamination, and even if you were really careless with that there's no risk to a healthy adult. The only concern is for an unborn fetus (or someone with a compromised immune system), and in that case most people just have they're husband clean the litter and that's that. You can get it and never notice you're sick and then you're immune to it forever. Actually, I think you're much more likely to get it from a piece of undercooked meat or an improperly washed fruit or vegetable than a cat, so no need to stress! 

If she was an outdoor cat before the shelter she probably did get exposed to a lot of stuff, which hopefully the shelter has cured her of, but keep an eye out for diarrhea. It's not a big deal and easy to deal with, I just mention it because it seems like shelter kittens always have something but it's easy to solve with a vet visit. One of the many good reasons to keep your cat indoors!

It is more common for you to get it from meat than from a cat. In a cat it is shed in their feces. If you wash your hands well after scooping the litter box you should be fine. There is a blood test (or at least use to be, probably pretty pricey as it isn't done often and usually has to be sent to a lab to see if your cat is a carrier). Not all cats are carriers and even if your cat is that doesn't mean she will show symptoms as it usually doesn't really affect cats in an ill way.

Good anwers here.  So the real danger of infection is bigger and much more common is  from other, everyday sources.

and basic normal hygiene  levels the actual danger from cats to practically nil.  Its pure automatic instinct to wash hands after you scooped their litter, no?

Why people are afraid for cats, is I think, the newspapers, now and then, when they dont have anything else to write about, no Marsians, no terrorist attacks nor school shootings, no nothing - what to do, what to do?? Yes, you guessed: they publish instead an article on how horrible and dangerous cats are.   "Just look. you can even get toxoplasmosis from them!"

Wow! Thankyou for your replies.
Will keep up the good hygiene practice and just enjoy our little kitty who happens to be pretty amazing after just a week its like she's been here forever! Thanks.
