What is Listeriosis, Probable?

**Listeria monocytogenes** was first identified in animals in 1926 by E.G.D. Murray. It was recognized as a cause of human disease in the 1930s, gaining significant public health attention with large foodborne outbreaks in the late 20th century. It remains a crucial food safety concern due to its severe impact on vulnerable populations.

Symptoms

  • Fever and muscle aches
  • Nausea, vomiting, or diarrhea
  • Headache, stiff neck, confusion, loss of balance, or convulsions (if infection spreads to the brain or spinal cord)
  • In pregnant women: often mild, flu-like symptoms, but can lead to miscarriage, stillbirth, or serious infection in the newborn.

Transmission

Listeriosis primarily spreads through the consumption of food contaminated with **Listeria monocytogenes**. This includes 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.

Contagious Period: Varies by disease

Prevention

  • Practice safe food handling: wash hands, separate raw and cooked foods, cook to proper temperatures.
  • Avoid unpasteurized milk and soft cheeses made from unpasteurized milk.
  • Thoroughly cook raw meat and poultry.
  • Reheat deli meats and hot dogs until steaming hot, especially for pregnant women and immunocompromised individuals.
  • Wash raw fruits and vegetables before eating.
