Now that I googled around a bit, I wonder just how much would make it into an egg.
@aart piqued my curiosity with her statement about it mostly staying on the skin and not entering the blood (since my understanding was that it DID enter the blood).
Check this out....
"The amount of fipronil taken into the body across the skin depends on the product formulation. Researchers applied a dose of 79% fipronil to the skin of rats and found that less than 1% of fipronil was taken into the body after 24 hours. When test animals have eaten fipronil, between 15 and 33% (goats) and 30 to 50% (rats) of the ingested dose was absorbed by the body. The rest of the fipronil was eliminated in the feces and urine."
So I know that doesnt address egg laying animals, and that maybe for egg layers a significant amount might come out in the eggs versus the urine or feces, but it does beg the question about how eating an egg from an animal that only absorbed 1% of the product would be any worse than the drop I get on my hand when I dose my dog. Or what I get from petting him over the next few weeks, etc...
All about each persons risk aversion level I suppose. Whatever floats your boat.
Anther anecdote, somewhat more related to birds.
"Fipronil was found to be highly toxic to some birds, but practically non-toxic to ducks."
