Which of the following foods is NOT at high risk for transmitting listeriosis?

Potato chips are considered a low-risk food when it comes to transmitting listeriosis. This is primarily because potato chips undergo a process of frying that typically eliminates pathogens, including Listeria monocytogenes, which causes listeriosis. Additionally, potato chips are dry and do not provide a suitable environment for bacteria to grow.

In contrast, soft cheese, hot dogs, and raw vegetables are known to be at higher risk. Soft cheeses, especially unpasteurized varieties, can harbor Listeria, while hot dogs may become contaminated if not heated properly. Raw vegetables can also be contaminated through soil or water and may not undergo cooking processes that would eliminate bacteria. Thus, potato chips stand apart as a snack food that does not bear the same level of risk for listeriosis transmission.
