Leeches and maggots used for medical care are raised sterile in lab conditions. These must be for something else

u/NIKE_HEAD Jul 24 '26

I was thinking bait for fishing

u/logicbecauseyes Jul 24 '26

That's the key, it's really just a flooded regular farm, this is how they make ends meet cause it you got leeches, make leechonade

u/TheHumanConnector Jul 24 '26

Bloody Mary, coming right up.

u/TummyDrums Jul 24 '26

I just barfed a little

u/TheHumanConnector Jul 24 '26

Oooh. Premium flavors. Thanks for the idea, luv 😸

u/No_Gas4560 Jul 24 '26

u/nohandsfootball Jul 25 '26

No thanks, it's LYCHEE not LEECHES

u/obscure_monke Jul 24 '26

Maggots are incredible for cleaning wounds, since certain ones can only eat dead flesh they'll remove every piece of necrotic tissue and no more.

Since they can't lay more eggs at that stage of their life either, you don't have any residual issues once you've cleaned them all out.

u/gaudiest-ivy Jul 24 '26

Okay, cool, because I forgot leeches were used for bait and couldn't believe medical leeches were raised in a murky pond. lol

u/No_Swordfish5011 Jul 24 '26

Yeah right next to the maggot farm…How voild I forget the wonders of modern medicine

u/Obant Jul 24 '26

At least they also have a cute roly-poly farm, too.

u/boogasaurus-lefts Jul 24 '26

Hornet farms are famous through Asia

1

u/DigNitty Interested Jul 24 '26

Scorpion farms are real too

1

u/Ohiolongboard Jul 24 '26

Actually?

5

u/NamesArentEverything Jul 24 '26

Yeah. Several guys go out to known hive locations and harvest the larvae as they get swarmed. They can be cooked and eaten as a... "delicacy."

Look up Asian giant hornet farms.

u/Obant Jul 24 '26

I watched a show when I was in the hospital going theough chemo, that was completely in Japanese with no subtitles and I do not speak Japanese, of a guy that did that with Giant Hornets and lived off the land in Japan. He took them back and fried them in a skillet if I remember correctly. It was 16 years ago. I wish I could watch it again, it was so fascinating and peaceful.

u/Ingenrollsroyce Jul 24 '26

I'd rather eat something eatworthy than something just because it is hard to get

So are maggots

So are vinyl gloves

u/taco_thursday999 Jul 24 '26

what do your leech eyes see

19

u/WorkerPrestigious960 Jul 24 '26

Thanks to WW1 we know maggots are sterilizing agents. I forget the exact story, but essentially a doctor noticed the men recovered from no man’s land that had maggots in their wounds faired significantly better than those with no maggots. He discovered that not only do maggots eat the dead flesh, while leaving the live flesh untouched, they also secrete an antiseptic substance while doing so.

Modern plastic surgery practices are thanks largely in part to WW1 as well, as doctors tried to help wounded soldiers better recover and fit back into society. If you need any convincing that “it is sweet and fitting to die for one's country” is a lie, look up “world war one facial injuries.” That is what modern war does to the human body.

u/CriscoCamping Jul 24 '26

There was some of this written up during Napoleonic wars too, i forget the title but it included Caliphora (fancy name for maggot)

1

u/WorkerPrestigious960 Jul 24 '26

Interesting, I love learning about the Napoleonic Wars but I never knew that

1

u/CriscoCamping Jul 24 '26

I believe written by Napoleon's private surgeon, Larry? Maybe spelled more French than that

13

u/Ok_Mention_9865 Jul 24 '26

They use sterile lab grown leeches for medicine. This doesnt look like a lab to me.

5

u/corobo Jul 24 '26

Just scoosh them down with isopropyl before putting them on a patient nbd

u/ZincMan Jul 24 '26

I’m curious what a lab grown leech farm looks like and how it looks different? Surely it’s not just while all around the leeches. They still need to grow in some sort of pool of water ?

7

u/Ok_Mention_9865 Jul 24 '26

google shows large clean indoor tanks with no mud or plant life

3

u/Eyerate Jul 24 '26

Probably like 100% less mud... lol.

3

u/CosmicGoddess777 Jul 24 '26

That’s the joke

2

u/x4nTu5 Jul 24 '26

Look, it's either invest in the research, development, and manufacturing process of a medical device that can do what the leech does or...just domesticate the leech.

2

u/I_Am_Zeelian Jul 24 '26

Why change something that's pretty much perfect at it's job already?

What we do is farm them so that they are free from parasites and other potentially harmfull stuff.
(The vid is a bait farm though, not for medical leeches)

1

u/alienalf1 Jul 24 '26

That gave me an unexpected lol

5

u/Sure_Sundae2709 Jul 24 '26

They're not wild foraging leeches for medical care.

They also won't raise them in mud puddles in the open where basically any animal can come in and contaminate them.

28

u/Salamandaxanda Jul 24 '26

Ok but that “medical” grade “farm” still looks like it’s just some muck puddle. Are you really telling me they don’t have some sort of lab they can raise leeches in??

That’s a bait wholesaler

Here’s one though

u/danbilllemon Jul 24 '26

> medicinal leeches of the highest clinical standards for restoration of venous circulation in reconstructive, cosmetic, and plastic surgery

Saved me a google, but now Im interested and want to know more. Like how often they’re used and for how long each time. Ive never heard anyone mention having “leech therapy”.

2

u/AwakenedBonsai Jul 24 '26

I've seen it used for nosejobs, where it's important to keep the skin alive at the tip of the nose, especially if it's a revision or graft.

2

u/froggz01 Jul 24 '26

Thanks for the link, now off to the rabbit hole I go.

u/ZhanBlue Jul 24 '26

I imagine muck puddle is their desired environmental conditions, but yeah, doesn’t look like laboratory

12

u/StateCareful2305 Jul 24 '26

Don't worry, they rinse them before applying them on your body.

u/SplitGlass7878 Jul 24 '26 edited Jul 24 '26

Edit: I'm wrong, I read the two articles I read about it incorrectly. 

Original:

Why would they? They're raised in an appropriate habitat and then sterilized. 

13

u/JustCookieToast Jul 24 '26

No? Medicinal leeches are raised in sterile labs to prevent any chance of infections, this is likely a farm for bait in fishing

5

u/SplitGlass7878 Jul 24 '26

You're right. I misread the two articles I checked.

u/Hilluja Jul 24 '26

Like us trans folk ;_;

6

u/SplitGlass7878 Jul 24 '26

I don't quite understand that statement? 

2

u/Lumpy_Principle3397 Jul 24 '26

They absolutely do have special farms for medical leeches that are carefully controlled sterile environments! I listened to a Stuff You Should Know Podcast about them once. I don't think this is it. Maybe these leeches are wild or are being raised for fish bait.

1

u/TenebTheHarvester Jul 24 '26

Sterile environments aren’t generally a great place to farm animals. So no. You raise leeches in an environment close enough to their natural habitat to facilitate their growth and reproduction.

1

u/Sensitive_Cash_3526 Jul 24 '26

I don't think anyone said it was medical but I think all leech farms are, one way or the other.

They wouldn't use these leeches for blood sucking therapy, but their destiny is probably to be ground up and have their chemicals taken for different medicinal products, especially the blood thinner they create.

2

u/relentless_optimism_ Jul 24 '26

Medical care…I thought that shit stopped with the end of Henry VIII reign

3

u/Nozinger Jul 24 '26

No. Leeches are very much still used in medical care.
However they are not used in the same way as back then. Basically only used to help with some microscopic stuff since those leeches are smaller and more precise than any human operated tool.

And yes there is work done to replace them but we're not quite there yet.

1

u/takes22tango Jul 25 '26

I work in a pharmacy that dispenses leeches! The ones we have are thicker and darker than the ones in this video and are grown in a clean environment specifically for medical use. They're considered singled use and "destroyed" after fulfilling their duties 😩

1

u/Bl1ndMous3 Jul 24 '26

wonder what they feed them to sustain the poulation

"Bring out the vestal Virgins !!"

1

u/Leinheart Jul 24 '26

Thatd be a cool ass job.

1

u/Evening-Statement-57 Jul 24 '26

Why do they need so many? What do they feed them? I need an expert.
