Thrush and maggots

So this morning my farrier called me to tell me he was cleaning my horse’s feet out and noticed believe it or not there were maggots in it! It is the hind right foot and there is a small wound there on the heel of the hoof. I went out to look at him and called my vet to come out. My vet checked it out and it looks like thrush that had gotten into the heel of the foot and infected. He cleaned it out, packed it and we are starting antibiotics.

I just feel like the worst horse mom ever for not even noticing. He has always been prone to thrush and as soon as I see the first sign of it I always start treatment. This just didn’t look like thrush though. He has flaky heels and it just looked like that. The vet told me to keep the packing on for three days then flush the wound everyday with iodine. He and the farrier also talked and agreed on a game plan for future prevention. I am also supposed to start applying hooflex everyday.

I also wanted to start him on a hoof supplement. Anyone have any recommendations? Or any experience with thrush and maggots? I usually use Thrush Buster for the thrush but if anyone has any other ideas let me know. Also, he lives in a stall during the day and a totally dry, mud-free pasture at night so I have no idea as to why he gets thrush so easily.

You caught it and are treating it, so don’t feel too badly. The flies are horrendous this summer, and I’m sure there are a lot of horses with summer sores–down here in the swamp, they’re fairly common. I know of one vet who treats them with oral ivermectin bosules (meant for cattle); I don’t recall the exact dosage, but it might be something to look into. Of course, just keep the wound clean & covered, and that should help quite a bit.

For thrush, I personally believe White Lightning is your best bet. A lot of thrush treatments just help a little bit & perpetuate the problem, but White Lightning actually clears it up. A few treatments a week for a month or so and you should be good to go.

Personally, I spray my horse’s hooves with an ACV/tea tree oil combo to keep him from getting thrush, but I believe the most important things you can do are make sure the hooves are properly trimmed & balanced, ensure the diet includes recommended amounts of vits/mins, and allow the horse lots of room to move around(since movement=blood flow=healthier hooves). Anything you apply topically is just a tiny factor in overall hoof health and most topicals do little to nothing. I personally don’t think Hooflex is going to help at all with this situation.

I have heard good things about Thrush Off and No Thrush powder, and they might help a little (or help with prevention later), but it sounds like you really need the big guns on this case (White Lightning).

Best of luck!

If it makes you feel better, when I worked for a university veterinary hospital we were doing a lot of work with maggots for medicinal use-- treating deep infections of the hoof, often associated with laminitis. They probably were helping clean it up it a bit. :wink:

The farrier and vet discussed how to prevent thrush in the future? What about you? Were you involved in that conversation? Or is that their job alone?

The only time I’ve seen maggots in a thrushy foot was when when the horses lived in an environment that was a little on the damp side, moreso on the filthy side. These horses’s feet hadnt’ been picked in a very VERY long time.

If you’re dealing with thrush regularly, you may wish to consider bumping up overall cleanliness & moisture removal in your stables and paddocks. You also may have to consider daily packing of the feet, regardless if you think there’s an active infection going on or not. Packing crevices of feet where moisture and anaerobic bacteria likes to hide (and thrush) gradually makes them bigger. Bigger crevices mean more air, less chance for bugs who like humid, tight places to grow.

If your horse has contracted heels, what is the farrier doing about that?

And by packing, I dont’ mean hoof packing. I mean drag-a-ball-of-cotton-through the cracks 'till it comes out clean. Only after you’re sure you’ve removed all the thrush, do you pack more cotton as deeply as the horse allows and saturate it with the thrush medicine of choice. I personally like Today or Hetacin K for mastitis in cows.

Simply slapping ointments on the outside of the foot won’t prevent thrush or maggots, and hoof supplements take a year to affect the horn to grow out. If they work at all. This is going to take daily attention and daily work.

The use of maggots in medicine, shouldn’t ease your mind that in any way, shape or form that this is ‘okay’. Maggots eat necrotic tissue. In other words issue that is dead. And for medicinal purposes, the maggots are raised in a sterile, or as close to sterile environment as possible. That’s a far stretch from what’s occurring naturally with your horse.

Frankly, I’m a little grossed out and horrified. I am thrilled you are too. Which means this won’t happen again to horses in your care anytime soon.

I think I have tried every hoof supp under the sun and hands down the best results I get is from Dumor Hoof. I do keep both the horses I have on it at the initial double dose always. They are big guys.

Maggots are pretty easy to boil out of wounds (unless very deep punctures) with peroxide. If you have a stubborn one or two hiding deep then go out at night with a flashlight. Pour peroxide on and let it boil a bit. Light the wound with the flashlight and the little buggers should be there. Pull them out with tweezers quick. Repeat until they are all gone.

Thrush can happen even in fairly clean environments. The anaerobic bacteria that causes it is eveywhere pretty much (not just in filthy environments) and only need moisture. We fought thrush last year with all the flooding in the spring for a couple months.

Just about everything works on thrush from Coppertox, to iodine, to bleach. But on horses that tend to get cracks and layers of nasty frog I prefer Durasole. It seems to penetrate into the frog much better.

Once the hoof is unhealthy…well it amounts to a bit of a battle until you grow out healthy hoof. As Texarkana mentioned, think about laminits possibly being the root cause. Fighting a nasty case of hoof rot on a cow just now. She was very sick a few months ago with a high fever. I do see now that her hooves are growing out that her high fever caused some laminitis while she was ill. She not very happy with me at the present time but we have several weeks of work left to do. She is just going to have to be unhappy for a bit longer.

Keep in mind that anything caustic (like bleach) is going to kill both the thrush AND healthy hoof tissue, giving the other bacteria/fungus/etc. in the environment something to feast on (aka a thrush smorgasboard). It’s a vicious circle. Best to just clear it up with something that kills all the bad stuff but does zero damage to healthy hoof tissue.

Oh, and yes maggots are disgusting and we should take their presence very serioursly (like the OP is doing), but, as I said earlier, the flies are so bad this year and it’s surprising how quickly a wound can become a summer sore. I never saw one until I moved to Florida, but I have seen them on several well-cared-for horses down here–any little wound they have, the flies will lay eggs in it and before ya know it you have maggots. Not saying they’re acceptable or no big deal, but they’re more common than I would have thought. As long as it’s being properly treated, no foul on the OP’s part in my opinion.

Hoof supplements are tough. It will take about six months to even have a guess if it is doing anything and just because a supplements seems to be helping one horse it might do nothing for the next horse. Have you looked at your horse’s entire diet to make sure there are no holes there first?

I had good luck with Right Balance hoof supplement for my horse.

how often are your stalls cleaned? It doesn’t help if all the wet material from the stall isn’t removed and your horse has to stand around in it all day. Even though I’m at a full service barn they only clean once a day-so I started making sure to do another cleaning anytime I’m out there.

Of course I was also involved in the conversation with the vet and farrier as well. I was the one who facilitated this coversation. I thought it was important for myself, the farrier, the vet and the barn owner to all be on the same page as far as treating the issue now and preventing it in the future. For now the plan is to leave the packing on for 3 days and then it will be removed and I will flush it with the medication the vet left everyday. In two weeks the vet wants the farrier to work on the hooves. In addition, both the farrier and vet noticed how hard the sole and frogs of his feet were and told me to apply the Hooflex ointment on all hooves everyday.

I am not sure how I can improve cleanliness and such beyond what I am doing right now. He is boarded at one of the nicest and also most expensive barns in my city. His stall is always dry and gets cleaned twice a day. He goes outside in a grass pasture that is never, ever wet. In fact, we haven’t had rain where I live for nearly a month. In addition, I ride him almost everyday and pick his feet out before and after every ride. I believe this infection set on quickly and I did not intially notice it because it was on the heel/bulb of his hoof, not a normal location for thrush. He also has very flaky heels and the vet believes that is how the thrush set in.

I am also aware that the hoof supplement would not work immediately but I am willing to try it to prevent future issues and see if it improves the overall quality of his hooves.

With any horse that is “prone” to thrush, a full evaluation of the horse is needed.

What is the horse’s environment like? Are stalls deeply bedded and cleaned thoroughly every single day? If not that needs to start. Drying the foot out is important and lots of dry clean shavings will do that. Where is the horse turned out? Although mud can’t usually be avoided, a sacrifice paddock filled with muck and manure is not a suitable t/o situation!

After environment is dealt with, you need to assess your farrier’s trimming and shoeing practices. Contracted heels, narrow feet, and deep crevices will trap debris and moisture, which contributes to thrush.

Next you evualate diet. Are there any vitamins/minerals missing? Your horse should have high quality hay and a full grain ration or rb or a multi-vitamin. Poor nutrition will contribute to thrush.

Finally look at the topicals you are using to TREAT the thrush. Products like Thrush Buster are ok for occasional use but IME have never made a dent in a serious case of thrush. My go to soak is CleanTrax, although White Lightening seems to be more available and will also do the job. Tomorrow (cow mastitis treatment) will get into deep infected grooves and clear up thrush. Goldbond foot powder is my favorite daily maintenance as it is DRY so it will dry out the hoof!

As for maggots, I believe I saw a study with medical maggots (do they even exist?) and using them to eat dead tissue on the horses hooves in severe thrush cases.

:confused: You want the sole and frogs to be nice and tough/hard, not mushy. Heck, since we are in monsoon season here, I’ve been applying Keratex Hoof Gel to my horse’s hooves several days a week to protect them from the moisture so they will stay nice and hard and not get all soft.

Can you post pics of the hooves?

I have a new discovery, which I found when trying to figure out how to fix up the feet of my 2 rescue ponies. They had horrible thrush and white line disease. It is called Banixx and this stuff WORKS and is totally NON-offensive. No smell, no sting. I couldn’t believe it really did anything until my ponies’ feet were healed!

I’ve had a vet pack sterile maggots into a hole in my horse’s hoof after it was surgically debrided (chronic abscess/keratoma?). These fly larvae stayed packed and bandaged in the hoof for about 2 weeks. Their job was to eat all the leftover diseased tissue and it worked perfectly!

But maggots establishing themselves and on their own in your horse’s hoof - that is unusual. Does your horse move around much or is he just confined to a stall?

I’ve got to think there is something really, seriously wrong in the foot if a horse that has his feet picked regularly and doesn’t live in a bog pops up with maggots. Is he really seriously contracted in the heels? Are his feet too long? Does he perhaps have a lingering pocket of infection from a foreign object?

It takes a couple days for eggs to hatch and develop into maggots, I think? Which would mean this isn’t something that could just pop up overnight…

I wondered about a foreign object in the hoof as well. My horse once had a really terrible case of thrush that I just could NOT get resolved. He was not being turned out at the time (rehabbing a suspensory injury), so I thought that was how it came about - even though I picked his feet out twice a day, and his stall was cleaned three times a day. He was never lame on the hoof, even when it was so disgustingly infected that I could smell it from outside his stall.

I ended up having my vet cut out all of the infection while my horse was sedated for an ultrasound. The vet’s opinion was that my horse had likely stepped on a piece of metal or other foreign body, which punctured the frog and lodged deep in the hoof. The hoof likely then sealed around it, with an entry area that would have been so small that I would not have noticed it. We never did find the foreign object, which the vet surmised must have disloged on its own at some point after the infection started.

It was seriously so disgusting that I wanted to vomit. My horse was at a top notch facility with extremely large, extremely clean/dry stalls, and I personally picked his feet out twice a day, so I do think these things can happen despite very good care. But I think there is usually some reason for it…like a foreign body. What about getting an x-ray of the hoof to see for sure?

thrush comes from wet and or dirty enviroment
and if one doesnt treat it with respect then it can become secondary

its a bacterial infection which some horses are more susceptible to than others
Thrush in horses is a foul smelling bacterial infection affecting the feet. It should not be confused with canker, which is an altogether more serious infection. Fortunately, canker is rare as it is a difficult condition to cure, whereas thrush usually resolves with correct management.

Careful stable and hoof management is essential if thrush is to be prevented. As the bacteria are killed by oxygen, regular use of the hoof pick will allow air to the foot and reduce the ability of the bacteria to take hold.

Keep stables clean with plenty of good-quality, dry bedding. If horses are in for long periods, bank the beds during the day to allow them to stand on an area of clean, dry concrete.

Some horses are more susceptible to this condition than others, and foot conformation can lead to a predisposition to thrush. For example, a deep cleft in the frog may become packed with sand after working in an arena. If not carefully cleaned, this could lead to irritation and allow bacteria to enter.

The prime cause, however, is one of hygiene — standing in droppings and urine. The damp conditions of a dirty stable provide the perfect environment for the anaerobic bacteria, (those needing a low-oxygen environment) which cause thrush to flourish.

Diagnosis and treatment

The most obvious sign of thrush is a foul-smelling, black discharge from the frog, which itself may have softer spots and appear irregular in shape. The horse is unlikely to be lame unless the decay has invaded the sensitive inner tissues.

If a horse has thrush the underlying cause needs to be identified and removed. The horse should be moved to a clean, dry environment and the feet cleaned daily.

The farrier or vet will need to remove the decayed tissue, and depending on the severity of the condition, this may need to be done over more than one visit. The feet may need to be bandaged or dressed with topical medication. Every vet and farrier has their favourite remedy, most of which aim to dry out the feet.

Thrush will never resolve unless the hoof hygiene is good — it is the equine equivalent of athlete’s foot. A damaged frog is the perfect entry point for the bacteria that cause tetanus, so ensure that the horse has adequate protection against this.

please understand that thrush can become secondary infection if left alone or not treated on a daily basis till gone and can be very painful to a horse or any equines
please understand that you must call for a vet and farrier and have xrays done if nessacary to see any changes of the foot/feet

I feel like his environment is very clean. He is boarded at a top-notch hunter/jumper facility where the stalls are cleaned twice a day. They are always bedded deeply as well. Heck, the stalls look so clean and dry I’d sleep in it! Also, the pasture he is turned out in is always dry. I don’t think I’ve once seen mud it in.

Diet wise, he always has access to good-quality hay. He is also fed Purina Strategy and has access to a mineral block.

I will look into other types of thrush treatment and try other things. It is just this issue presented so differently to any thrush I’ve ever seen before. In regard to his shoeing job, I had one guy do maybe 2 or 3 visits for me who I was unhappy with because he was putting him in too-small shoes and made the crevaces too deep. I switched and this guy does a great job. He is a drafty breed so he does have larger hooves.

I will try and post pictures of the other feed but I can’t take pictures of the infected foot until the packing comes off Friday. My vet is also coming to check up on him then so I will ask about the possibility of a foreign object. Thanks for the help everyone. I’ve felt awful these couple days thinking I am such a terrible horse owner because I didn’t catch this sooner.

mate its actually cleaning his feet out on a dialy basis that will prevent it
once a day yeah really it should be done before he goes out and when he comes in and any other time he is used before and after
