Ok, so when I went to the workshop in Oakland there was a talk by an entomologist who specializes in poultry parasites. She said that fipronil has not been approved for use on chickens and she recommended NEVER eating the eggs or the meat of a chicken that has had fipronil used on it.
She stated that for cattle, the withdrawal time for eating the meat or the milk is 200 days, so that's where I got that figure from. I also found on parasitipedia.net that the withdrawal time for cattle is "3-4 months."
I decided to go with the 200 days figure as far as eating the eggs, because based on this website, the effect on humans as far as chronic consumption of fipronil is not likely to cause any harm to us. It is far more likely to cause poisoning to the chicken, though, since chickens are super sensitive to this chemical, more sensitive than mammals.
So basically it shouldn't be used on chickens at all but since it's consumption is not likely to harm me I am not going to follow the advice to NEVER eat the eggs or meat again. I certainly will not be using fipronil again in the future though.
Here is the website; it's has lots of information: http://parasitipedia.net/index.php?option=com_content&view=article&id=2686&Itemid=2991
it does not go through the bloodstream . did they say why? or just that it has not ben tested in the meat or eggs?
