What is Listeria infection?

It is a bacterial infection, also known as listeriosis, which is transmitted through foods contaminated with listeria, a bacteria that is especially dangerous for pregnant women, immunosuppressed people, and older adults.

Listeria infection typically occurs by eating sausages contaminated by a poor production process, products made with unpasteurized milk, raw, unsanitized vegetables, or contaminated meats.

In pregnant women, who are more susceptible to contracting a listeria infection, it may not cause major problems for them. Still, it can be fatal for the baby, causing spontaneous abortion, intrauterine fetal death, premature birth, or infection with fatal consequences after birth.

It can also be devastating for people with the following characteristics:

Older adults.
Individuals with a depressed immune system.
With HIV/AIDS.
In chemotherapy sessions.
Diabetics.
Kidney failure.

The most serious complications of a listeria infection can be septicemia or meningitis.
