Costco Cucumber Salmonella Outbreak

Washington State health officials are working with state, local and federal public health partners to investigate the source of six Salmonella infections.

The six cases include residents of King (1), Snohomish (1), Thurston (1), Yakima (2) and Pierce (1) counties. All were infected with the same strain of Salmonella bacteria. The last confirmed case reported illness on Sept. 15.

Five of the six people reported buying and eating English cucumbers from various Costco stores in Washington. The cucumbers linked to the illnesses were sold in three-packs of individually wrapped cucumbers.

This outbreak has been linked to a current outbreak in Canada that has sickened 45 people. The investigation is still ongoing.

Symptoms of Salmonella include:

  • Diarrhea
  • Abdominal cramps
  • Fever of 100-102 F
  • Bloody diarrhea
  • Vomiting
  • Headache
  • Body aches

Symptoms typically appear 6-72 hours after eating contaminated food and last for 3-7 days without treatment. If you or a family member experienced symptoms, contact your local health department.
