Which serotype was linked to a dry dog food outbreak in 2012?

• A. Typhimurium
• B. Enteritidis
• C. Infantis
• D. Newport

Answer: (C)

When investigators traced illnesses from 2012 back to a dry dog food product, the specific Salmonella serotype identified was Infantis. Matching the strains found in patients with the strains found in the contaminated pet food confirmed the outbreak source. This shows how typing Salmonella serotypes helps connect human cases to a particular exposure, and highlights that dry pet foods can harbor Salmonella and spread it to households through handling. Other serotypes, such as Typhimurium, Enteritidis, and Newport, are commonly linked to different foods or sources, so they don’t fit the 2012 dry dog food outbreak as this one does.
