WASHINGTON – Salad greens from Dole and Fresh Express packaging plants have been recalled after three deaths and 22 hospitalizations due to listeria contamination. It’s massive recall: 400-plus products under various salad-kit brands:

> Dole.

> Kroger.

> Giant Eagle.

> Little Salad Bar.

> Market District.

> Marketside.

> Signature.

> Simply Nature.

> Weis.

Among symptoms: Fever, headache, diarrhea. The kits, of varied mixtures of greens, are sold in plastic bags ranging from 5 to 32 ounces. The U.S. Centers for Disease Control said the strain of bacteria matches a strain linked to 16 listeria illnesses over the past seven years. Dole suspended operations for “an extensive cleaning and sanitation protocol.”
