#2: Toxoplasma Gondii: A Parasite Found in Cats That Can Live in Your Brain Forever
In this episode I talk about a parasite that might already be in your brain. It's called Toxoplasma gondii and some studies say over half the world could be carrying it without even knowing. It reproduces in cats but spreads through things like undercooked meat unwashed produce and contaminated water. Most people don’t feel a thing but for folks with weaker immune systems or if you're pregnant it can get dangerous. I break down how it works how it spreads and why simple habits like washing your veggies and cooking your food properly actually matter more than you think.

Transcript
What if I told you that right now, more than half of the people on Earth could be unknowingly hosting a parasite in their brain?
Speaker A:Meet Toxoplasma gondii, a predator lurking in the shadows of your everyday life.
Speaker A:This insidious parasite has a life cycle that's both complex and terrifying.
Speaker A:It reproduces only in the intestines of cats, the parasite's only definitive hosts, but can also infect you as intermediate host.
Speaker A:When cats consume infected prey like mice, the parasite survives their digestive system and takes residence in their small intestines.
Speaker A:Here, Toxoplasma gondii undergoes reproduction, creating millions of potent eggs.
Speaker A:These eggs are then expelled in the cat's feces.
Speaker A:And here's the real horror.
Speaker A:They are resilient and are able to survive on unwashed vegetables, raw meat and in contaminated water.
Speaker A:The eggs can live on surfaces for months, making them nearly impossible to eradicate.
Speaker A:Ingestion of just one of these eggs can expose you to this silent threat.
Speaker A:The health impacts can be severe.
Speaker A:In healthy people, Toxoplasma gondii can cause flu like symptoms that might seem benign, but there are studies relating toxoplasm infection to increased risky behavior, anxiety and depression.
Speaker A:If you think about it, a risky rat is an easy meal for a cat.
Speaker A:This sneaky adaptation makes it easier for the parasite to transmit from host to host.
Speaker A:For those with weakened immune systems, the consequences can be even more severe, leading to organ damage, death.
Speaker A:Not to mention, if this parasite infects a pregnant woman, it can cross the placenta and infect an unborn child.
Speaker A:So how can you protect yourself?
Speaker A:Basic sanitary safety practices are crucial.
Speaker A:Wash fruits and vegetables thoroughly and avoid raw or undercooked meat.
Speaker A:Freezing meat for several days can kill this parasite, and cooking meat to the recommended temperatures is essential.
Speaker A:Also, you should take precautions when cleaning your cat litter box, especially if your cats like risky prey.
Speaker A:But beware.
Speaker A:Even with these precautions, the threat of Toxoplasma gondi remains.
