To date, whole genome sequencing has identified a total of nine individuals across multiple states infected with this Listeria outbreak strain, including one death in Maryland that occurred in 2023. The Maryland Department of Health will not release additional information about the individuals to protect their privacy. 

L. monocytogenes is a type of disease-causing bacteria, part of the Listeria family, that can grow in unsanitary food production conditions, leading to contamination of the food. When people eat food contaminated with L. monocytogenes, they may develop a disease called listeriosis. It can survive and grow even under refrigeration, and can easily spread to other foods and surfaces. Pets can also spread the bacteria in the home if they eat food contaminated with L. monocytogenes.

Listeriosis can cause a range of symptoms that vary depending  on the severity and form of the illness. It can be serious and life-threatening, particularly for pregnant women, newborns and young children, older adults, and persons with weakened immune systems. Mild symptoms include fever, muscle aches, nausea, vomiting, and diarrhea, which often persist for 1 to 3 days. For the more serious form of the disease, symptoms may include headache, stiff neck, confusion, loss of balance, and convulsions. Although people can sometimes develop listeriosis up to 2 months after eating contaminated food, symptoms usually begin within several days. People should immediately consult with a healthcare provider if they suspect they have developed symptoms that resemble a listeriosis infection. 

Consumers at higher risk for Listeria illness should not eat any soft cheeses that are made with unpasteurized milk. Although pasteurization of milk kills Listeria, soft cheeses made from pasteurized milk can still become contaminated after the pasteurization process and cause Listeria illnesses.

This represents the best information currently available to the Maryland Department of Health.
