In the United States, 16 people were infected with Listeria, one died, and one pregnant woman miscarried

According to ABC on November 10, the US Centers for Disease Control and Prevention announced that through an investigation of six states that reported listeria outbreaks, it was found that the outbreak had infected 16 people, hospitalized at least 13 people, and one pregnant woman had aborted
due to listeria infection.
In addition, according to the news released on November 9 local time, Maryland reported 1 death
.

The U.
S.
Centers for Disease Control and Prevention reports that most of those infected had eaten meat or cheese from deli counters in recent days, and the center is working to identify specific products
that may be contaminated.

The U.
S.
Centers for Disease Control and Prevention also reported that 11 of the 16 cases were of Eastern European descent
.
Currently, cases
have been reported in California, Illinois, Maryland, Massachusetts, New Jersey and New York.

Listeria is known to be the causative agent of listeriosis, and infection generally occurs after
eating contaminated food.
Every year, about 1,600 people are infected with Listeria and 260 die.

Among them, pregnant women, people over 65 years old, and immunocompromised people are at the greatest
risk of infection.

The U.
S.
Centers for Disease Control and Prevention reminds people to avoid infection by washing refrigerators and related containers that have been exposed to deli meat or cheese, and avoiding meat and cheese
from deli counters.

Listeria is a foodborne pathogen
that can cause diseases such as abortion, sepsis, and meningitis in animals and humans.
Newborns, the elderly, pregnant women, and immunocompromised patients are at high risk of Listeria infection
.
In developed countries, the incidence of clinical listeriosis is about 2/100,000~15/100,000, and the mortality rate is 13%~34%.

There are approximately 2,500 cases of listeriosis in the United States each year, including 500 deaths
.
Therefore, although listeriosis cases are not as common as other foodborne diseases, it is still the second deadliest foodborne infectious disease
after salmonella infection.
Listeria can make humans and animals sick, and the main manifestations of sepsis, meningitis and mononucleosis after infection are 20%~30
%.
It is widely present in nature, people eat meat, milk eggs, aquatic products and vegetables have different degrees of pollution, the World Health Organization (WHO) on Listeria monocytogenes food poisoning report pointed out, 4% ~ 8% of aquatic products, 5% ~ 10% of milk and dairy products, more than 30% of meat products, more than 15% of poultry are contaminated
by the bacteria.
Listeria monocytogenes present in food poses a great threat to human safety, and the bacteria can still grow and reproduce in an environment of 4 °C, and is one of the
main pathogenic bacteria threatening human health in refrigerated food.

Studies have shown that about 10% of human digestive systems grow Listeria
.
However, veterinarians are the bulk of clinical cases of Listeria, and meningoencephalitis infection in ruminants is the most evident
case.

Listeria is quite pathogenic, can infect the fetus in the abdomen through the woman's genitals, causing meningitis, so pregnant women are usually not recommended to eat soft cheese that has not been sterilized at low temperature, such as: Bry, Camembert, Feta cheese, XoBlanco cheese, etc
.
In addition to Listeria, these microorganisms hidden in food can cause food poisoning!
