    This document will be of interest.
    Note "lifetime withdrawal" means never eat eggs from that hen again because of persisting residue OR lack of information on product in laying hens

    What the vets are saying is that per farad any pesticide not specifically labeled for poultry is considered extra label use. Extra label use in laying hens of pesticide is unpermitted
    But I will ask the vets on the chicken vet group for the specific info for fipronil
    Additionally per US regulations Sevin has been banned from the use in laying hens since 2010

    And that says
    Meaning if the label does not specify poultry it cannot be used on them without "lifetime" withdrawal

    Thanks for the link... that's the only one I found, and I don't read it as "banned", I read "Terminate Uses or Eliminate Certain Application Methods", but not banned... [​IMG] To me there is a huge difference between banned and "not labeled" or "not approved".

    I understand that vets cannot prescribe extra label use of pesticides, but that does not mean that when we use something like carbaryl or fipronil that we can never eat the eggs or meat of that bird.

    With pesticides there is no off label use permitted if it does not specify a food animal species it cannot be used on them
    It is not my interpretation of the law all the vets on that page agree I suspect if you yourself wrote to farad as the website says you can they would tell you more details
    Terminate use means banned in epa terms regarding a legal product and livestock

    I do know both Sevin and fipronil linger in the animals including repro tract in excess of 8 weeks per residue testing not sure if they discovered how long it stays but all the avian vets and farm vets agree the use of those products = never bring able to sell eggs or meat from those birds because of the rules
