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.

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.

Even more produce products sold in multiple states, including Ohio, were recalled by the FDA due to a high threat of potential salmonella contamination.

Grocery store product recalls happen more than many customers realize and often affect millions of people and hundreds of stores across different states.
