NPIP/Biosecurity Workshop

The Nation Poultry Improvement Plan (NPIP) is a voluntary program administered by the USDA, the various states, and the poultry industry.  Begun as a national program in 1935, it was designed to improve the poultry industry by controlling and eradicating Pullorum disease and fowl typhoid from poultry flocks, improving the selection of breeders and sanitation practices.  Participation was, and still is, voluntary; the incentive to participate being the use of official NPIP logos on advertising and containers and the ability to ship product across state lines or internationally easier.  Although still a voluntary program, state and federal regulations make it difficult for a poultry business of any size to operate without participation.

            The program has been so successful that Pullorum and fowl typhoid infections are rare, and many states, such as South Carolina, are proud to claim the status of an U.S. Pullorum-Typhoid Clean State.  To retain Clean status, laws are necessary that require all poultry entering the state to be “U.S. Pullorum-Typhoid Clean” or equivalent or enter the state with an interstate veterinary inspection certificate (iCVI) showing a negative Pullorum-Typhoid test within 30 days.  All SC poultry going to exhibitions must be “U.S. Pullorum-Typhoid Clean” or tested negative within 90 days.  There is no NPIP or state requirement for poultry moving to immediate slaughter.

            Because of the success of the NPIP, only commercial primary breeder flocks need to be tested every year.  Commercial multiplier flocks supplying eggs to “U.S. Pullorum-Typhoid Clean” hatcheries have been allowed to reduce annual testing to a zero level.  All hatching eggs and day-old poultry moving in commerce must be “U.S. Pullorum-Typhoid Clean”.  Started poultry (birds that have been fed and watered) may retain their NPIP status up to 6 months of age if they are housed on a NPIP participating farm.

            An Authorized NPIP Testing Agent is a person licensed by the state plan to perform Pullorum-Typhoid tests that can be performed in the field or to obtain samples for laboratory testing only within the state of South Carolina. 

Becoming an Authorized NPIP Testing Agent (SC NPIP Tester) is an optional part of the SC NPIP & Small Flock Workshop.  For those interested, read this study material in order to take the test during the workshop.
