All Deli meats have a theoretical risk of acrrying the listeria bacterium. However, the risk is very small, so I personally have made the decision to eat deli meats. Even soft cheese. But that is just my decision.
Heat destroys the bacteria, so cooked soft cheeses and deli meats are fine (like blue cheese in a pasta sauce or cooked ham or bacon).

In Europe, they don't even advise people against eating those things because the risk is so small these days with our hygiene standards.

I would however make sure I buy and eat it from reputable sources, where it has been well chilled, eg. not left in the sun at a BBQ.

Theoretically you could contract listeria from eating raw vegetables. So really, we shouldn't even eat salads.
You should always make sure you wash any vegetables you use very well.
