Sixteen products containing cucumbers sold at Kroger stores in nine states have been recalled. The Food and Drug Administration announced the recall Wednesday, May 28, as part of an ongoing investigation into cucumbers possibly contaminated with Salmonella.

(NEXSTAR) — Additional salads and vegetable trays sold at Kroger stores in nine states have been voluntarily recalled in response to a multistate salmonella outbreak connected to cucumbers.

Salmonella causes symptoms from diarrhea and fever to severe, sometimes life-threatening infections in vulnerable groups. U.S. consumers are being urged to thoroughly inspect their deli, salad, and produce purchases, as healthy individuals are at risk.
