Shigella in Leafy Greens: Memphis Food Safety Guide
Shigella contamination in leafy greens has posed a recurring public health concern in Memphis and across Tennessee. The Shelby County Health Department and FDA work to trace contaminated produce back to source farms and distributors. Understanding the risks and knowing how to respond can protect your family from foodborne illness.
Shigella Outbreaks Affecting Memphis
Shigella sonnei and Shigella flexneri have been linked to contaminated leafy greens shipments that reached Memphis retailers and foodservice operations. The CDC and FDA collaborate on trace-back investigations to identify the point of contamination—typically at the farm, processing facility, or during transport. Memphis residents who purchased affected spinach, lettuce, or mixed greens during outbreak windows faced heightened infection risk. The Shelby County Health Department issues advisories when local cases cluster and contaminated products are identified in local supply chains.
How Memphis Health Departments Respond
The Shelby County Health Department coordinates with the Tennessee Department of Health, FDA, and CDC to investigate Shigella cases and issue consumer alerts. When a contaminated produce batch is identified, the department works with local retailers, restaurants, and institutional food services to remove affected items and notify customers. Health inspectors conduct environmental sampling at farms and processing plants implicated in outbreaks. Public alerts are posted on the Shelby County website and coordinated with state epidemiologists to prevent secondary transmission.
Consumer Safety & Real-Time Alerts
Wash leafy greens thoroughly under running water for at least 20 seconds, even pre-packaged varieties. Store greens separately from raw meats to prevent cross-contamination, and discard any produce that appears wilted or discolored. The CDC recommends cooking greens to 165°F if you're immunocompromised or in a high-risk group.
