National Poultry Improvement Plan (NPIP)

​Illinois NPIP Flock Owners and Approved Poultry Testers:

August 19, 2020
The manufacturer of pullorum antigen has increased the availability of antigen to approved testers.  All testing requirements for poultry being imported or sold within the state are now reinstated.  To remain active in the Plan, all members of the National Poultry Improvement Plan must conduct an annual test as soon as possible.  If you need assistance in locating an approved tester, please contact the Bureau of Animal Health and Welfare at 217-782-4944.

What is the NPIP?

The National Poultry Improvement Plan was developed in the early 1930s by a State-Federal-Industry partnership to coordinate State programs aimed at eliminating Salmonella Pullorum from commercial poultry.

Adult birds infected with S.Pullorum normally show no outward evidence of infection, but they are disease carriers for life. Hens can become infected by eating contaminated feed, infected eggs, or manure from other infected chickens. The disease can be eliminated from flocks by blood-testing adult breeding birds, utilizing effective biosecurity techniques and good sanitation.

Since its initial goal of eliminating Salmonella Pullorum, the Plan has also included the following egg-transmitted diseases to eliminate from commercial poultry flocks: Salmonella Gallinarium (Fowl Typhoid), Salmonella Enteritidis, Mycoplasmas (M.Gallisepticum, M.Synoviae and M.Meleagridis).

Avian Influenza (AI) is a worldwide viral infection of poultry. An influenza virus has the ability to mutate or change its genetic character. An infected bird may show a wide range of signs: from no apparent signs, mild to moderate illness, to death. Because of the different symptoms of influenza, three levels of host disease are described: nonpathogenic, low-pathogenicity, and high-pathogenicity avian influenza. Because of the ability of the AI virus to mutate, the NPIP has added AI to its list of diseases to keep out of commercial poultry flocks.

How to become a member of the NPIP

For initial enrollment in the plan, an authorized poultry tester will test all of the adult birds (4 months of age and older) in your flock for Salmonella Pullorum-Typhoid up to a maximum of 300 birds.  A Bureau of Animal Health, Animal and Animal Products Investigator will meet with you to complete a Hatchery/Flock Agreement.  After the flock agreement and testing have been completed and reviewed by the Bureau, a NPIP flock number will be issued for the flock.

Once in the program, the flock owner may move, show or sell birds for a year. To remain in the program requires the flock owner have a portion of their flock tested once a year for Pullorum-Typhoid. A list of private authorized poultry testers in Illinois is available for a flock owner to contact to do their annual flock test. A flock can be removed from the program for failure to have their flock retested in a timely manner.

At this time there is no cost to get into the NPIP program. There may be a nominal charge to have an authorized tester do the annual retest in your flock.

To begin enrollment, please complete the fillable pdf NPIP  Enrollment Form ​and submit it to the Bureau of Animal Health and Welfare for processing.
