Where is listeria commonly found?

Listeria is a type of bacteria, specifically Listeria monocytogenes, that can cause a serious infection known as listeriosis. This bacteria is commonly found in certain food products, particularly those that are of animal origin. The correct response highlights that Listeria is frequently associated with milk products, soft cheeses, and uncooked meats.

Soft cheeses and unpasteurized dairy products can harbor Listeria if they are made from contaminated milk. Moreover, deli meats and uncooked meats can be contaminated during processing or handling. Listeria is particularly dangerous for pregnant women, newborns, elderly individuals, and those with weakened immune systems, making awareness of these sources vital for food safety.

The other options focus on less common associations with Listeria, as processed snacks, candy, bottled water, and soft drinks are not typical sources of this bacterium. While these items may carry other risks in terms of food safety, they do not commonly harbor Listeria compared to the products noted in the correct answer.
