The saying "illness comes from the mouth" is true.

According to media reports, the U.S. Centers for Disease Control and Prevention recently announced that by investigating six states that reported listeria outbreaks, the outbreak has led to 16 infections, at least 13 hospitalizations and one miscarriage of a pregnant woman due to listeria infection, while one death was reported in Maryland, according to news released on Nov. 9 local time.

The Centers for Disease Control and Prevention reported that most of those infected had eaten meat or cheese from the deli counter in recent days, and the center is currently working to identify specific products that may have been contaminated.

Listeria monocytogenes is a parthenogenic anaerobic bacterium that is the causative agent of listeriosis, and it is one of the most deadly foodborne pathogens, primarily using food as a vector of infection.

Patients infected with Listeria monocytogenes are very dangerous and have a mortality rate of up to 30% if treatment is delayed or left untreated, however, if the disease is managed with timely treatment, patients are largely able to recover completely.

It is widely distributed in nature, its ability to survive in the 0-45 ℃ environment, even in the refrigerator refrigeration environment can still grow and reproduce, so it is also known as "latent refrigerator killer".
