How does Listeria monocytogenes get into food? – USDA
Animals can carry Listeria monocytogenes (Lm) in their intestines without becoming sick. As a result, the bacteria may be spread to meat and dairy products. Listeria monocytogenes (Lm) is killed by cooking or by other heating methods, such as pasteurization, used to produce ready-to-eat foods. However, ready-to-eat food can become contaminated after processing within the processing plant or along the route from the plant to your plate. Outbreaks of listeriosis are associated with ready-to …

Listeriosis is a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes. An estimated 1,600 people get listeriosis each year, and about 260 die. The infection is most likely to sicken pregnant women and their newborns, adults aged 65 or older, and people with weakened immune systems.

Listeria monocytogenes – an overview | ScienceDirect Topics
Listeria monocytogenes is a ubiquitous microorganism responsible for listeriosis, a rare but severe disease in humans, who can become infected by ingesting contaminated food products, namely dairy, meat, fish, and vegetables. Although it can occur in healthy humans, listeriosis mainly affects the elderly, immunocompromised, persons pregnant women, and newborns, with a high case-fatality rate (20-30%). This article will summarize what is currently known about

What is Listeria monocytogenes and how does it cause food poisoning?
A person with Listeriosis usually has a fever, muscle aches, and gastrointestinal symptoms such as nausea or diarrhoea. If the infection spreads to the nervous system, symptoms such as headache, stiff neck, loss of balance, confusion or convulsions can occur. With brain involvement, Listeriosis may mimic a stroke.

Aerosol and Airborne Transmission of Listeria Monocytogenes: A … – USDA
Non Technical Summary It is widely assumed that Listeria monocytogenes can be transmitted to processed foods by means or airborne or aerosol transmission. Airborne bacteria may best be defined as bacteria which are attached to dust particles, while aerosolized bacteria may be defined as bacteria which are suspended in liquid, which then become airborne by physical actions which develop droplets. However, there is very little scientific data to support this assumption, or to provide the …

Can Listeria be transmitted from Person to Person? – Epainassist
Listeria monocytogenes is found in wastewater, in food, in animal feces, and even in the feces of healthy people. The listeries can be reproduced at low temperatures and even at low temperatures that means, also in the refrigerator. Can Listeria be Transmitted From Person to Person? There are different ways of transmission of listeriosis.

How Listeria crosses the placental barrier to infect the fetus
A study conducted by the group directed by Marc Lecuit (Avenir Inserm / Group Microorganisms and barriers host the Pasteur Institute), at the Inserm unit U604 directed by Pascale Cossart, has uncovered how the bacterium responsible for Listeriosis (Listeria monocytogenes) can cross the placenta of pregnant women to cause serious fetal infections —even death—, premature birth and infections …
