How Much Of A Health Risk Is Listeria Really?

From the consumer’s vantage point, it seems like Listeria contamination in major food brands is on the rise these days. Are the outbreaks actually increasing, or are we just more aware of them? That may not be such an easy question to answer at this juncture, but safety measures in food manufacture will surely be intensified as a result...

Listeria is a particularly ugly pathogen since the number of people who die from it relative to the number infected is quite high. From 2011 data, it seems that about 1600 people are infected from listeria each year, and 260 die. In contrast, only about 380 people die from the 1 million cases of Salmonella in the country each year.

  How Much Of A Health Risk Is Listeria Really?

Listeria is a particularly ugly pathogen since the number of people who die from it relative to the number infected is quite high.

Listeria Blog

The Listeria blog supplements Marler Clark's Web site www.about-listeria.com, a site that provides information about Listeria monocytogenes, the symptoms and risks of infection, testing and detection of Listeriosis, and how to prevent the spread of the Listeria bacterium.

CDC

Listeriosis, a serious infection usually caused by eating food contaminated with the bacterium Listeria monocytogenes, is an important public health problem in the United States. The disease primarily affects older adults, pregnant women, newborns, and adults with weakened immune systems. However, rarely, persons without these risk factors can also be affected. The risk may be reduced by recommendations for safe food preparation, consumption, and storage.

FoodSafety.gov

Listeria is unlike many other germs because it can grow even in the cold temperature of the refrigerator. Listeria is killed by cooking and pasteurization.

Mayo Clinic

Listeria bacteria can be found in soil, water and animal feces. Humans typically are infected by consuming: •Raw vegetables that have been contaminated from the soil or from contaminated manure used as fertilizer •Infected animal meat •Unpasteurized milk or foods made with unpasteurized milk •Certain processed foods — such as soft cheeses, hot dogs and deli meats that have been contaminated after processing. Unborn babies can contract a listeria infection from the mother via the placenta.

MedicineNet

In most people, Listeria infection symptoms and signs mainly include the common symptoms of food poisoning such as fever, nausea and vomiting, diarrhea, abdominal pain and cramping, back pain.

MedlinePlus

Listeriosis is a foodborne illness caused by Listeria monocytogenes, bacteria found in soil and water. It can be in a variety of raw foods as well as in processed foods and foods made from unpasteurized milk. Listeria is unlike many other germs because it can grow even in the cold temperature of the refrigerator.

NHS

In most people, listeriosis is mild and causes symptoms including a high temperature (fever), vomiting and diarrhoea. These symptoms usually pass within three days without the need for treatment. However, in rare cases, the infection can be more severe and spread to other parts of your body, causing serious complications, such as meningitis. Common signs of severe listeriosis include a stiff neck, severe headache and tremors.

Patient

Listeria spp. are not very pathogenic to healthy adults, who are likely to experience only mild infection, causing flu-like symptoms or gastroenteritis. However, listeriosis can occasionally lead to septicaemia or meningitis. Pregnant women, the elderly and people with weakened immune systems (including those treated with oral corticosteroids) are more susceptible to listeriosis.

StatPearls

Listeria monocytogenes is a facultative, intracellular, gram-positive rod that is responsible for causing the infection listeriosis. Listeria causes severe infection in the elderly, neonates and the immunocompromised with only a self-limited gastrointestinal infection in the immunocompetent.

TextbookofBacteriology

Listeria monocytogenes is a Gram-positive rod-shaped bacterium. It is the agent of listeriosis, a serious infection caused by eating food contaminated with the bacteria. Listeriosis has been recognized as an important public health problem in the United States. The disease affects primarily pregnant women, newborns, and adults with weakened immune systems.
