The case count has continued to grow as state health officials work with Public Health — Seattle & King County along with other local, state, and federal partners on the disease investigation. The federal Centers for Disease Control and Prevention (CDC) sent its team of “disease detectives” to the state to help. Investigators are interviewing the most recent cases and comparing information to early cases, which were first reported in the spring.
Disease investigators are searching for possible contamination and exposure sources from a wide range of possible venues, including restaurants, markets, slaughter facilities, and farms/ranches. Salmonella bacteria are commonly found in animals used for food, and proper storage, handling, preparation, and cooking can help prevent the illness known as salmonellosis.
Most of the illnesses have been confirmed with the outbreak strain of Salmonella 4,5,12:I:- bacteria, and early testing shows a connection to a slaughter facility in Graham, WA. Samples were collected at Kapowsin Meats in Pierce County last week. Testing confirms the outbreak strain was present. The business, which is regulated by the United States Department of Agriculture Food Safety and Inspection Service, has cooperated with the investigation. There may be other sources and disease investigators are searching for the origin of the Salmonella bacteria in the outbreak.
The 134 cases include residents of Clark (2), Cowlitz (1), Grays Harbor (1), King (84), Kitsap (1), Mason (2), Pierce (12), Snohomish (24), Thurston (2), and Yakima (5) counties.
In May 2015 public health officials in Kenosha, Wisconsin investigated an outbreak of Salmonella linked to food purchased over Mother’s Day weekend (May 9-10) at the Supermercado Los Corrales in Kenosha. More than 70 people were reported to be ill. Thirty five patients were laboratory confirmed with Salmonella 4,5,12:I:-. Patients were infected with an indistinguishable strain. The outbreak strain was isolated in pork carnitas. The meat and food preparation areas of the facility were closed during the investigation.
