Being NPIP guarantee that your flock is free from typhoid and pullorum free at the time of testing. These diseases can come in at any time after testing so it is not always 100% fool proof.
 
I buy all my birds from NPIP sources and have sold hatching eggs and birds without any problems within state and out of state. Had one tester done on all of my birds, all tested negative for those two diseases.
 
People now are testing flocks for MP/MG free. Even roughly 80 percent of the birds will have it.
 
So how that I am not being responsible? I am being responsible on my end, ensuring my flock are healthy, free from T and P and bottom line, it is buyer's beware. We all take risks more than others while others will not. It is not any different than bringing your birds from the shows or never show them, somehow, somewhere it will happen and NPIP is false security. And I will not have the government in the livestock division telling me what I can raise and not raise.
 
Ask many breeders about NPIP status, they will do everything they can to keep the diseases out of their flock but once they leave their flock, there is absolutely nothing they can do about it.
 
Would I go NPIP? No.
 
Does USPS check for NPIP status? No, it is not their responsibility to make sure your birds have been tested. Had two postal inspectors saying no, they do not check NPIP status, nor have the man power to make sure it is updated but it is the primary responsibility of both parties of seller and buyer to determine the health of the birds. Sure I have sent two EE;s to NY about seven years ago and never had any issues, as well as the chicks and one other started birds without the NPIP papers. I've had two breeders that has NPIP and they never included papers with it. Neither does Ideal Hatchery either.
 
It is the most responsible thing for us breeders to maintain the health and buy from reliable sources for our flock. Maybe we should work on getting our flock MG/MS/LLV negative as well as Avian Flu negative. A simple bloodwork from your own vet can get it done without the NPIP papers if you want to take that route. I've done it and was pleased with our avian vet and be able to work closely with him regarding to all chicken diseases and the chances and risks involved. I can sell a bird if the seller wants bloodwork done on it (at their cost) and it will be done.
 
Common sense prevails. You can practice your own bio security without the NPIP papers.
