What is Listeriosis, Confirmed?

*Listeria monocytogenes* was first identified in animals in the early 20th century and later recognized as a significant human pathogen. The bacterium was named after Joseph Lister, a pioneer in antiseptic surgery. Large foodborne outbreaks in the latter half of the 20th century significantly raised public health awareness regarding Listeriosis.

Symptoms

  • Mild/Flu-like (can occur in healthy adults or pregnant women): Fever, muscle aches, nausea, diarrhea.
  • Severe/Invasive (if it spreads to the nervous system): Headache, stiff neck, confusion, loss of balance, convulsions.
  • In pregnant women: May cause mild maternal symptoms but can lead to miscarriage, stillbirth, premature birth, or life-threatening infection in the newborn.

Transmission

Listeriosis is primarily transmitted through the consumption of food contaminated with *Listeria monocytogenes*. Common sources include raw or undercooked meats, unpasteurized dairy products, soft cheeses, deli meats, and raw produce. Pregnant women can also transmit the bacteria to their unborn or newborn babies.
