Toxoplasmosis in Whitetail?

Hey all, just wanted throw out there something I, really my wife, learned today. This is slightly off topic of hunting, but not really. I’m gonna try and lay out this little story as best I can.

So in 2015, my wife was at her eye dr getting her usual checkup. She had recently switched dr’s and he is very thorough with his exams. Well he noticed during one test, that she had a spot of some sort in/on her retina. He was uncertain exactly what to make of it, so he referred her to a retina specialist.

She sees the dr, who might I add, was about 352 years old, but was an extremely smart man. He told her it was most likely Toxoplasmosis. Most likely given to her from her mom during pregnancy or contracted from cats as a child, but that there was no way of knowing how long she had it. Good news was that it was dormant, and wasn’t doing any type of damage since it couldn’t grow and wasn’t in her “sight path” or whatever their terms are. You could tell by the dark black lines around it, supposedly that meant it was done and couldn’t go further. Said it was nothing to worry about and then sent her on her way. He didn’t go into much detail about it, and we didn’t research it much since she was in no danger.

Fast forward to last week. She goes back for her yearly exam, and since her dr had seen the spot before, he always checks it really close for any additional changes. It’s always the same, until this time. A new spot has formed near the other spot. So again, sent to specialist. Today was that day. We get to the specialist office, find out the other dr she had seen had retired last year, and there was a new dr that had taken his place, much younger. This dr isn’t set in his old ways and seems much more connected to you. Well, the new spot has hazy edges, which means it’s active and growing.

I know you’re wondering what this has to do with deer hunting, and here it is. As soon as he looks at the spot, he asked “do you or someone close to you deer hunt?”. Well of course my eyes got big and she cut her eyes over at me.. I initially think he’s going the “tick bite” route. I told him I did, he asked if she eats deer meat, and of course the answer was yes. He said for the longest time, dr’s thought Toxoplasmosis was only transferred during pregnancy or through cats (scratches, poop, I don’t know), but in the last couple years of his practice, he said all of his patients with Toxoplasmosis has one thing in common, venison..

When he said that, I thought, “we live in the south, 99% of people eat venison, so of course everyone has that in common”. But he said that Toxoplasmosis is a parasite/disease that has recently been discovered heavily in the whitetail deer population. It is unknown if the parasite is killed during cooking or not, so they don’t know if it’s from undercooked meat, or just the meat.

So, now, on top of worrying about the possibility that I’m gonna bring home a tick or something and end up giving my wife or young son some kind of Lyme disease or something, now I learn that just by eating the meat, they could be exposed to a parasite. Now, I haven’t done much research on it yet, but what little I gathered, it typically shows no symptoms to people that have it and up to 50% of the population have Toxoplasmosis Gondii, and don’t even know it (probably me haha). But in very rare occasions, in adults usually, it can cause eye lesions that, if not treated or go dormant on their own, can cause blindness. Go figure, deer meat can make you blind ha. The most common symptoms are in children that are given the parasite/disease by there mother, have difficulties at birth that are usually treatable.

So in short, for giggles, when you go for your eye exam, ask the dr if they can check your retinas pretty good for any type of small lesions or spots. Then you can get some treatment before you possibly go blind, then you won’t be able to hunt the deer that blinded you! Hahaha. Anyways, if you have any information about this, let me know. I’m gonna do some research on it, although, too much internet research can scare the crap out of you ha.
 
Really wish I hasn't read this
Ha I’m not afraid of it or gonna let it slow me down any, but man, just one more thing to add to list things to watch for... used to be ticks, then with all the cwd/ehd you had to watch for brain matter and bone marrow or something. Now I learn this.. geez... I guess it’s still safer than most sports/activities haha
 
Hey—wildlife biologist here.

Im sorry to hear of your wife’s recent diagnosis, but glad she is exposed to good treatment and caregivers.

Toxoplasmosis does persist in WTD, and is more prevalent in urban deer populations most likely due to larger populations of feral cats. More can be read here: https://www.qdma.com/well-done-frozen-venison-prevents-toxoplasmosis-infection/

Make sure to thoroughly cook venison and use separate tools, cutting boards, etc than what you and your wife use everyday in the kitchen. As always, keep any processing tools/knives clean. It would be a good idea to freeze venison before consuming it. Hope this helps!

Seriously, thank you for sharing that.

There goes my sales pitch to my wife on continuing to eat true "organic" healthy meat. Is PETA behind this? We just can't win, on one hand you have steroid/antibiotic riddled meat or toxoplasmosis/CWD.

To be safe I am going to start eating fast food and gas station hot dogs to avoid illness.

Thank you very much for the information and link! So it appears, without reading it yet, that the freezing kills it rather than cooking killing it, I’ll be sure to share this with my wife, thank you again!

Lol! Even the vegans are unsafe these days with all of the pesticide use. Ya cant trust all of those “organic” labels according to a chemical engineer i know.‍♂️

Everything is dangerous for us! At least the gov’t tells us so, and they can’t lie to us! Hahahahahahaha! Just don’t eat gas station sushi!
 
Thanks for the information. Freezing meat is definitely the way to go. My wife read the provided link and is on the case! LOL. By the way, I do have my own set of butchering utensils
 
Yeah I freeze mine also, and I have a set of skinning knives, that’s my only “utensils” that touch the meat before freezing.
As far as my wife, I seriously doubt she got it from a deer. Her mom was one of those that would take in every stray cat and dog that came around, I feel confident she got it at an early age when she lived at home or possibly from her mom before birth, though we’ll never know.
It was just a shock to know that it could happen through deer. I’m almost curious enough to get bloodwork done on myself for it, almost ha. Somethings I’d rather not know.
I read the link provided by @HappyChappy , and it was very informative and also “comforting” so to speak in the sense that it’s something that is preventable and you’re not necessarily risking it every time you eat deer meat. I just wish it something I’d known about before finding out this way.
 
I'm an optometrist and deer hunter, so I'll weigh in. First, I'm sorry to hear of your wife's diagnosis. I know from experience in my family that visiting a retinal specialist can be a scary situation. It sounds like the affected area is in a good position and it was caught early. Far and away, patients I've seen that get treatment early with active toxoplasmosis retinitis do very well.

Retinal lesions due to toxoplasmosis have been reported in the literature related to venison consumption; however, all the cases I've read about have found uncooked or undercooked venison to be the culprit. There have been reported cases from consumption of undercooked pork and beef also, so the fact that it's venison isn't necessarily the problem. There is also much more scientific evidence that contact with cats is a higher risk factor than eating venison.

I have not seen any retinal studies that mention freezing like the QDMA report that @HappyChappy provided, but that make sense it would kill off anything you don't want in the meat.

In the end, I think properly cooking and/or freezing all venison makes the risk extremely low.

Now I'll be able to sleep tonight. Thank you @aes7.5x55

Thank you for that, and yeah, I am 99.9% sure she didn’t get it from venison. I was just in shock about the fact it was even possible.
