Under the National Poultry Improvement Plan, the Pullorum-Typhoid Clean classification is required for all poultry types except ostrich, emu, rhea, and cassowary. This statement is true.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (A)

The main idea is that NPIP requires Pullorum-Typhoid Clean status for most poultry to prevent transmission of Salmonella pullorum and S. gallinarum from breeders to offspring. There is an exception for ratites—ostrich, emu, rhea, and cassowary—where this standard requirement does not apply and these species follow separate health certification pathways. This is why the statement is true: all typical poultry types need PT Clean status, except these four ratite species.
