Which organism is not included in NPIP testing and monitoring?

• A. Salmonella enteritidis
• B. Newcastle Disease
• C. Salmonella typhi
• D. Mycoplasma meleagridis

Answer: (B)

NPIP testing targets specific poultry pathogens that have direct implications for food safety and flock health, mainly certain bacterial agents such as Salmonella species and some Mycoplasma pathogens. Viral diseases fall outside this program’s scope and are managed through other surveillance and control efforts. Newcastle disease is a viral illness, so it isn’t part of NPIP testing and monitoring. The other organisms listed are the kinds of pathogens NPIP focuses on because of their relevance to product safety and poultry health: Salmonella enteritidis and Salmonella typhi are Salmonella strains of concern for eggs and poultry products, and Mycoplasma meleagridis is a Mycoplasma organism associated with poultry health that NPIP includes in its monitoring.
