The Washington State Department of Health and Public Health—Seattle & King County, with CDC and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA-FSIS), continue to investigate an outbreak of Salmonella I 4,[5],12:i:- infections linked to pork products in Washington.

As of August 27, 2015, 152 people infected with the outbreak strains of Salmonella I 4,[5],12:i:- have been reported from Washington.

24 ill people have been hospitalized. No deaths have been reported.

Epidemiologic, laboratory, and traceback findings have identified pork produced by Kapowsin Meats as a likely source of this outbreak of Salmonella I 4,[5],12:i:- infections. This investigation is ongoing.

On August 27, 2015, Kapowsin Meats issued an expanded recall of approximately 523,380 pounds of pork products that may be contaminated with Salmonella I 4,[5],12:i:-.

Recalled pork products include whole pigs for barbeque and fabricated pork products including various pork offal products, pork blood, and pork trim.

Pork products were produced on various dates between April 18, 2015 and August 26, 2015.

Products subject to recall bear the establishment number “Est. 1628” inside the USDA mark of inspection.

This recall expands the August 13, 2015 Kapowsin Meats recall of approximately 116,262 pounds of whole pigs.

Consumers should check their homes and freezers for the recalled pork products and should not cook or eat them. Retailers should not sell these products and restaurants should not serve them.

CDC’s National Antimicrobial Resistance Monitoring System (NARMS) laboratory conducted antibiotic resistance testing on clinical isolates collected from 10 ill people infected with one of the outbreak strains.

All 10 isolates (100%) were multidrug resistant. This included resistance to ampicillin, streptomycin, sulfisoxazole, and tetracycline.

Antibiotic resistance may be associated with increased risk of hospitalization, development of a bloodstream infection, or treatment failure in patients.

CDC’s NARMS laboratory continues to conduct antibiotic resistance testing on additional isolates, and results will be reported when they are available.
