Snohomish County Woman Hospitalized after consuming Listeria tainted Pasta

Snohomish County Health Department officials have confirmed that a Snohomish County resident is among those affected in a multistate outbreak of Listeria monocytogenes, a serious bacterial infection linked to contaminated food products.

The woman, whose identity is being withheld for privacy, was hospitalized earlier this month and is now recovering. She is the first person in Washington state connected to this outbreak, which is linked to prepared pasta meals.

A total of 27 people infected with the outbreak strain of Listeria have been reported from 18 states. California 3, Hawaii 2, Florida 1, Illinois 1, Indiana 1, Louisiana 2, Michigan 2, Minnesota 1, Missouri 1, North Carolina 1, Nevada 1, Ohio 1, Oregon 3, South Carolina 1, Texas 3, Utah 1, Washington 1. Sick people’s samples were collected on dates ranging from August 1, 2024, to October 16, 2025. Of 26 people with information available, 25 have been hospitalized and 6 deaths have been reported. One death from each of the following states: Hawaii, Illinois, Michigan, Oregon, Texas, and Utah. One pregnancy-associated illness resulted in a fetal loss.

Listeriosis, the disease caused by the bacteria, can feature a range of symptoms, including fever, muscle aches, nausea, abdominal pain and diarrhea. Listeriosis is especially harmful to people 65 years or older, people with a weakened immune system, and women who are pregnant. In severe cases, it can cause debilitating headaches, confusion, seizures or loss of balance.

Federal health agencies and public health officials have been investigating Listeria monocytogenes infections since August 2024 linked to the prepared meals. So far, the Centers for Disease Control and Prevention (CDC) reports 27 cases across 18 states, with six deaths. The U.S. Food and Drug Administration (FDA), the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS) are also investigating.

Listeria bacteria are found in the environment and can spread from contaminated food to surfaces. Listeria can grow on foods kept in the refrigerator for several days.

To prevent Listeriosis infection:

• Avoid unpasteurized (raw) milk or foods made from unpasteurized milk.
• Thoroughly cook raw meat, such as beef, pork, or poultry.
• Wash raw vegetables thoroughly before eating.
• Keep uncooked meats separate from vegetables and from cooked foods and ready-to-eat foods.
• Wash hands, knives, and cutting boards after handling uncooked foods.
