The E. Coli outbreak linked to a rotisserie chicken salad sold by Costco that’s sickened 19 customers in seven states has been traced back to a single ingredient: celery that comes from a supplier in California. That farm has now issued a recall for a slew of products that could contain tainted celery sold at 13 additional retailers across the country.

The Food and Drug Administration issued a notice that Taylor Farms Pacific of Tracy, CA is issuing a recall for items that may contain the celery in question. Along with Costco, 7-Eleven, King Sooper, Pantry, Raleys, Savemart, Tonys, Albertsons, Safeway, Vons, Starbucks, Target, Walmart and Sam’s Club are all included in the list. Click here for a complete list of the products being recalled.

The items vary — some are simply diced celery mixes, while others are pre-made salads — potato, pasta, tuna, chicken, etc. — or kits to make your own salad containing the possibly tainted veggies.

This strain of E. Coli can cause an illness that could develop into a form of kidney failure, the FDA notes, which is most likely to occur in young children and the elderly, so it’s important to remain vigilant. If you’re worried you’ve become ill from eating the products, contact your health care provider.

Thus far, 19 people have been infected with E. coli in California, Colorado, Missouri, Montana, Utah, Virginia, and Washington.

Customers who have any of the recalled products should toss them straight in the garbage. You can call 209-830-3141 for any further information Monday to Friday, between the hours of 8am-5pm (PST).
