Which of the following is a foodborne pathogen commonly linked to deli meats and soft cheeses?

• A. Staphylococcus aureus
• B. Salmonella
• C. Listeria monocytogenes
• D. Vibrio

Answer: (C)

Listeria monocytogenes is notable for its ability to grow at refrigeration temperatures and persist in ready-to-eat foods. Deli meats and many soft cheeses are often consumed without cooking, so if they are contaminated, the bacteria can multiply slowly in the fridge and cause illness. Listeriosis can be especially severe for pregnant people, newborns, older adults, and those with weakened immune systems, making this pathogen a classic concern with deli meats and soft cheeses.

Staphylococcus aureus is more commonly tied to toxin production from improper handling of foods like meats, mayonnaise-based dishes, and dairy, rather than being a primary link to deli meats and soft cheeses. Salmonella is frequently associated with raw or undercooked poultry, eggs, and some produce or unpasteurized products. Vibrio is typically linked to seafood, especially raw or undercooked shellfish and seawater exposure.
