I am planning to do something controversial, eating eggs immediately after worming with Ivermectin.

It's safe. They actually inject Ivermectin into embryos chicks in eggs to inoculate them against infectious bronchitis, so they wouldn't very likely do that if it harmed development. https://www.researchgate.net/publication /359476970_Evaluation_of_ivermectin_antiviral_activity_against_avian_infectious_bronchitis_virus_using_a_chicken_embryo_model

I was searching the Googs forever looking for an answer to this, I love this thread! I have a question - can these same eggs be used for hatching? Does anyone have experience with that? I have someone wanting to purchase fertile eggs, but I don’t want to sell them if they will end up unviable or deformed. Thanks!

I can't speak to Ivermectin, I rotate dewormers, and didn't have the same level of experience I do today, so my ability to make accurate observation might be suspect.

I will say that I just finished a round of Fenben (SafeGuard) on my whole flock (chicks, ducks, goats, bunnies) in response to a concerning fecal (my cats and dogs are seen by the vet, clean floats and monthly treatment), anywhow, where was I?

Decaffeintated.

I've NOT seen any studies, though I've not looked specifically for them. BUT! I noted a distinct decline in shell quality (easily cracked) in my flock during the Fenben treatment. Its 6 days today after the last dosing, and I'm starting to see improvement (some of the eggs I throw back to them now bounce on my clay soils instead of cracking). Cause/Effect or simple Coincidence?? I won't know until I next treat with Fenben.

But its somehting to be alert for.

I'm conceding that Ivermectin residual will be present in my eggs for the next few weeks. What I am wanting to determine is effect on the human that consumes eggs with Ivermectin residual. Is it harmful? This is my question.

It's now 12:12 pm here. I did some yard chores, Cleaned up some poop in the run, and I am feeling normal.

There are mentions in articles about humans taking Ivermectin with a doctor's prescription that they may experience dizziness, I assume from the sedative effect it is supposed to exert on the parasites it's treating. So far, I'm no more dizzy than usual.

The problem with this experiment is that it may not have any immediate effect but how do we know it doesn’t have any effect further down the road?

One word. Well, maybe four. Chickens have short lives. If it does cause long term health issues, then they would be moot due to chickens not living the two or three decades it would take for them to appear. Due to this, labs would not bother running long term experiments.

It probably doesn't have any effect on DNA or all the chickens wormed with Ivermectin over the years would certainly have caused genetic issues by now.

Thanks for all this info everyone. I appreciate your willingness to be a Guinea pig @azygous and for the input of medical professionals as well.

Hubby and I are human docs. I've read extensively on Ivermectin. It's widely considered to be one of the safest drugs we have. They did studies with Beagles and gave pregnant Beagles very high doses during their whole pregnancies and never had an issue with the puppies. I wouldn't expect any issues, especially since chickens treated with it are treated using normal doses.

After discovering my flock has depluming mites, I ordered Ivermectin 1% and Saturday, I treated every chicken in my flock. Since then, I've agonized over egg withdrawal protocols and searched high and low for information on why we observed this little ritual after we worm our chickens. Nothing out there tells me why we have to do this. What will happen to me if I eat these eggs? If I can't find a scientific or medical or even common sense answer to my question, I am forced to conclude a proscription against something may boil down to hysterical nonsense.

Therefore, in the absence of scientific studies on what happens to humans that eat eggs following worming with Ivermectin, I am going to conduct, if not an actual scientific study, at least an experiment using myself as the study subject. And this is a real time thread as I plan to march into the kitchen right now and cook some eggs and eat while reporting the experience as it unfolds.

It's is 10:06 am, and I just took my first bit of three scrambled eggs. I am now consuming them.

So a few years ago my husband insisted on eating duck eggs too soon after ducks had antibiotics but I forget the antibiotic name. He was fine. He is still fine.
Today I treated my hens with Valbazen and I read it’s a 14 day period plus second dose in 10 days makes it actually a 28 day withdrawl . Im not eating the eggs but I will let you know what happens to my husband.

Thank you for this thread and for BYC! I hope I am not asking a question that was already discussed but is there a difference in treating chickens topically vs. ingest vs. other methods? I just did a routine topical treatment with Ivomec. It was 7-8 drops at the base of the neck with feathers parted, so direct skin contact. I was curious if withdrawal periods or traceable amounts vary depending on delivery method?

Its complicated.

And yes, delivery method and drug both affect the dynamics. That said, withdrawal periods are offered (and studied) for specific drugs used in accordance with the label instructions. Used off label, there isn't a lot of publicly accessable research on a lot of the drugs, particularly for the establishment of withdrawal periods.

With the usual disclaimer I'm not a doctor, I clearly remember in biology class (OK I was top of class decades ago) that things go in to the body through the skin or ingested, or breathed in, but once in, they're in. So it wouldn't matter that they got it topically, they still got the ivermectin. Now the absorption rate and percent might be different, so that could affect any egg withdrawal period you're doing.
