Illnesses linked to Costco chicken salad in Washington

Less than a year after Costco recalled chicken salad that sickened people across seven states another outbreak linked to the club store’s rotisserie chicken salad has been revealed — more than a month after the suspect food was sold.

Only one Costco store was implicated as of Sunday when the USDA’s Food Safety and Inspection Service (FSIS) issued a public warning about Salmonella illnesses associated with the rotisserie chicken salad from store number 1190 in Lynnwood, WA.

“Based on epidemiological evidence, four Salmonella I 4,[5],12:i:- case patients have been identified with illness onset dates ranging from Sept. 2 to Sept. 6,” according to the FSIS notice.

“Traceback investigation indicated that three of these case patients consumed rotisserie chicken salad purchased on Aug. 26, Aug. 31 and Sept. 2 from this Costco location.”

The suspect chicken salad was produced Aug. 26 through Sept. 2 and sold in various sized containers directly to consumers at Costco’s Alderwood store in Lynnwood,WA.

“FSIS and the company are concerned that some product may be frozen and in consumers’ freezers. This product should be thrown away or returned to the place of purchase,” according to the public health alert. No product has tested positive for this strain of Salmonella.

“Clinical isolates associated with this investigation were tested for antibiotic-resistance, and three isolates from Washington State were found resistant only to tetracycline and susceptible to other antibiotics commonly used to treat salmonellosis.”

Anyone who ate the implicated chicken salad and developed symptoms of Salmonella infection should immediately seek medical attention and alert their doctors about the possible exposure to Salmonella I 4,[5],12:i:-.

The most common symptoms of salmonellosis are diarrhea, abdominal cramps and fever within 12 to 72 hours after eating contaminated food. The illness usually lasts four to seven days.

Most people recover without treatment. In some persons, however, the diarrhea may be so severe that the patient needs to be hospitalized. Older adults, infants, and persons with weakened immune systems are more likely to develop a severe illness. Individuals concerned about an illness should contact their health care provider.

Costco’s 2015 chicken salad outbreak
In the fall of 2015 at least 19 people across seven states were sickened with infections from E. coli O157:H7 traced to Costco rotisserie chicken salad.

Among people for whom information was available, illnesses started on dates ranging from Oct. 6 to Nov. 3, 2015. Five people were hospitalized. Two people developed hemolytic uremic syndrome (HUS), a type of kidney failure. No deaths were reported.

The Food and Drug Administration conducted a traceback investigation of the FDA regulated ingredients used in the chicken salad to try to determine which ingredient was linked to illness. However, the traceback investigation did not identify a common source of contamination.

On Nov. 20, 2015, Costco reported to public health officials that the company had voluntarily removed all remaining rotisserie chicken salad from all stores in the United States.

On Nov. 26, 2015, Taylor Farms Pacific Inc., voluntarily recalled the celery and onion diced blend used in the Costco chicken salad and many other products containing celery, because they might have been contaminated with E. coli O157:H7.
