What are the symptoms of listeriosis?

Question

Hello doctor,

As a mom, I am worried about the recent news on listeria outbreaks. I have heard it can cause a serious illness called listeriosis, but I am not clear on all the details. What exactly is listeria, and how does it spread in food? I know the Centers for Disease Control and Prevention provides updates, but what should I be looking out for? What are the symptoms of listeriosis, especially in children or pregnant women? How can I protect my family from this type of food poisoning? If you could clarify these points, it would help me understand the risks and take proper precautions.

Thank you.
