Study on Ivermectin residual in eggs, links

You don't. You get the Ivermectin for cattle and swine.

I use the pour on 1/4 ml for bantams, 1/2 ml LF.

this is a great post!

I can't open the link to the study about Ivermectin residual in eggs. Do any of you know what it says regarding how long to not eat the eggs? I've seen references online for throwing away eggs for as little as zero days to as much as an entire month. I hate to throw away any more eggs than I have to!

We've dewormed our chickens about every 2-3 months with pyrantel pamoate or fenbendazole (Safe-Guard/Panacur), and did a 3-day-in-a-row with the fenbendazole 2 months ago. We've never used Ivermectin, so I think we should introduce it into the program.

I am going to use the injectable ivermectin, but orally. Our chickens are laying almost every day at this time.

Thanks,

Toni

Toni, why do you have to worm your chickens so frequently?

 

[theperdews]

I have read that chickens should be dewormed every 3 months. We free-range our chickens, and they go into our horse pasture and pens in addition to the yard. Horses are never 100% free of worms, and I believe some of the worms are cross-species worms. Therefore, we assume that there is constant re-contamination potential since our chickens are free to roam during the daytimes. We also watch their combs, and when they begin to get lighter in color, we deworm. Sometimes, this is about at the 3 month time period, and their combs do get darker after deworming again.

Do you use diatomaceous earth and apple cider vinegar, too?

 

[theperdews]

I have read many mixed results with DE so am not worried about trying it. No on apple cider vinegar use previously.

Couldn't access the article, but did go poking around online. What I found so far (for chickens, not sheep, which are better researched) is that the ivermectin in eggs is almost exclusively in the yolk. I'll try to see sometime soon if there is any info on withdrawal time.

Might want to add: http://www.inchem.org/ to the list (covers just about everything under the sun).

I'd eat the eggs, myself. Actual (not relative) risk is negligible. If one is applying pour--on, without wearing gloves, the transdermal dose (through skin of hands coming into contact with the med/treated birds) is going to be the primary source of exposure (not the eggs).

Greatest danger to chooks/humans from this med, (clinical ED-50, levels) is that it kills so many parasites so quickly that the `rotting' `worm' waste systemically poisons the host:

The main effects noted in field and community-based trials with ivermectin in humans infected with Onchocerca spp. have been those arising from the death of the parasites, the so-called Mazzotti reaction, which is characterized by arthralgia, pruritus, fever, hypertension, tachycardia, headache, and ocular changes. Neither in these studies nor during ivermectic treatment of other parasitic diseases in humans in Africa, South America, the Caribbean, and certain other areas has a subset of atypically sensitive individuals been detected. Furthermore, the adverse effects experienced by the small number of persons accidentally exposed to doses (often of veterinary preparations) higher than customary human doses are in keeping with those noted in several test animal species.

I'd eat the eggs, too. Doesn't look to be a very harmful molecule. Metabolites would likely be harmless. I do wonder about flavor, though. Also, I tend to be rather insensitive to molecules I don't usually eat (no allergies). Others who receive my eggs are sensitive, however.
