(WFXR) — The Centers for Disease Control and Prevention (CDC) is investigating Dole salad mixes after linking two listeria deaths to packaged salads produced by Dole.

Dole issued recall notices in late December and early January with “best if used by” dates from Nov. 30, 2021 through Jan. 9, 2022.

Products being recalled include mixed greens, garden salads, Caesar kits, and many other types of salads in bags or clamshells.

You can also look in the upper right-hand corner of the package for the product lot code. Packages with a product lot code that begins with the letter “B,” “N,” “W,” or “Y” are part of the recall.

The CDC reported on Tuesday, Feb. 1 that that 17 people got sick and 13 people ended up in the hospital across 13 states, including Maryland and North Carolina.

The CDC says if you had Dole salad mixes during the start of the year, you’ll want to clean your fridge out really well as Listeria can survive in the refrigerator and can easily spread to other foods and surfaces. You can follow these steps to clean your refrigerator or any items that may have touched the recalled products.
