Listeria: Are You at Risk?


Sept. 29, 2011 -- Are you at risk from listeria, the deadly bacteria now in the news?

The death toll is rising in the ongoing outbreak from contaminated cantaloupe. It's now the largest outbreak of food-borne illness in more than a decade.

Suddenly the spotlight is on listeria. What is it? Where is it found? Who's at risk? What can we do about it? What are the symptoms of listeriosis, and how is it treated? Here's WebMD's FAQ.

What Is Listeria? Listeria monocytogenes leads a double life. It's commonly found in the environment, where it feeds on decaying plant matter. It's found in soil, animal feed, groundwater, and sewage. It can also be carried in the guts of cattle and poultry.

But when listeria gets into humans, it changes form. It becomes a bacterial parasite that lives inside -- and feeds on -- human cells. The disease caused by listeria is called listeriosis.

Because it's spread from cell to cell, it avoids the antibody arm of the immune system. Fortunately, the human cell-mediated immune system usually is very good at seeking out and destroying listeria-infected cells.

People with lowered cell-mediated immunity -- the elderly, cancer patients, people taking immunity-suppressing drugs, and pregnant women -- are particularly vulnerable to listeriosis.

How Do People Get Listeriosis? By far the most common way people get listeriosis is by eating foods contaminated with listeria.

However, newborns can be directly infected during birth. For every 100,000 U.S. births, there are 8.6 neonatal infections. Listeriosis is one of the most common causes of neonatal meningitis.

What Makes Listeria Dangerous? "Listeria is a very uncommon cause of illness," Patricia Griffin, MD, chief of the CDC's enteric disease epidemiology branch, tells WebMD.

That said, mild gastrointestinal illness from listeria probably is quite common. Listeriosis -- when listeria escapes the gut and invades the bloodstream -- is rare. The CDC now estimates there are only about 800 listeriosis cases a year in the U.S.

Whether listeria causes illness, Griffin says, depends on a combination of three things: a person's susceptibility, how much listeria a person has been infected with, and the virulence of the particular listeria strain.

Another thing that makes listeria dangerous is that it can survive for a long time, even at refrigerator temperatures.

"Listeria can live in microfilms," Griffin says. Microfilms are sticky mats of bacteria that don't easily wash away.

Microfilms may be one reason why listeria can survive and thrive for years in food processing plants.

But what makes Listeria most dangerous is that once it has entered the bloodstream, it gets into the lymph system and into the brain. Encephalitis and meningitis are major causes of death and disability in people with listeriosis.
