Health officials say the outbreak has been isolated so far to just the one store.
FSIS confirmed four people were infected with Salmonella, three of whom reported eating the Lynnwood Costco’s rotisserie chicken salad early last month.
This is not the first time Costco has had a problem with its chicken salad. Last December, at least 19 people in seven states were sickened with E. coli after consuming the same product.
One of those sickened was a 19-year-old woman who was hospitalized for months, lost her large intestine, and now requires dialysis and a kidney transplant to live.
In that outbreak, the likely culprit was found to be celery and onions in the salad, which was shipped to a number of Costco stores.
Salmonella infection, or salmonellosis, one of the most common bacterial foodborne illnesses reported in the United States. Symptoms include diarrhea, abdominal cramps, and fever within 12 to 72 hours after eating contaminated products.
The illness typically lasts four to seven days, and most people recover without treatment. However, the diarrhea may be so severe that some patients require hospitalization. Elderly people, infants and persons with compromised immune systems are most susceptible to the infection.
