LOUISVILLE, Ky. (WDRB) -- Have you checked your refrigerator? People in Kentucky and Indiana are finding recalled salad bags in their fridge, and some people have already eaten it.

WDRB sat down with an infectious diseases specialist with Norton Healthcare to learn about the deadly illness linked to the salads. The listeria outbreak has sent 12 people to the hospital, and one patient died.

Many people are tossing out bagged salad linked to a deadly listeria outbreak. If you have already eaten it, do not panic.

"Most likely if you've already consumed product and you're not ill, you're not going to get ill," said Doctor Paul Schulz, an infectious diseases specialist with Norton Healthcare. He says you can always call your doctor if you are still concerned.

"If you're young and otherwise healthy, you might get what we call gastroenteritis, nausea, vomiting, maybe diarrhea, it's folks that are immune-compromised who are at risk for infection," said Schulz.

That includes pregnant women. The Centers for Disease Control and Prevention say 12 people have been hospitalized in six states. One patient died.

The investigation began in September, but the source was not known until this month. The affected salads came from a Dole plant in Springfield, Ohio and have been sold in Kentucky and Indiana.

Dole Voluntarily recalled salads sold under these brands:

  • Dole
  • Fresh Selections
  • Simple Truth
  • Marketside 
  • Little Salad Bar
  • President's Choice

Recalled bags have a code on them that start with the letter "A." Some stores have started restocking Dole salad bags that come from processing plants that are not part of the recall.

Bagged or not, doctors say the biggest piece of advice they can give is to wash your produce, even if the bag says it has been thoroughly washed.

"Even if you buy it bagged and it says this has been washed three times, still washing it yourself would be a good idea, because you just never know when something might have slipped past the normal procedures and you can avoid illness by washing on your own," said Schulz.
