NANP Board Domain I – Food And Nutrition Practice Exam

Listeria is commonly associated with which foods?

Ground beef Soft cheeses Fresh produce Ready-to-eat deli meats

Correct Answer:

Ready-to-eat deli meats

Explanation:

Listeria can grow at refrigerator temperatures, so foods eaten without cooking are common sources. Ready-to-eat deli meats fit this pattern because they’re typically consumed without a cooking step, or only lightly heated, allowing any contamination to persist and multiply during chilling. This makes them a well-known vehicle for listeriosis, especially for pregnant individuals, older adults, and those with weakened immune systems. While soft cheeses and unpasteurized dairy can also harbor Listeria, the frequent consumer pattern of eating deli meats without heating is why they’re the most commonly associated option in this context.
