Shigella in Berries: Phoenix Safety Guide (2026)

Shigella Outbreaks in Phoenix & Arizona History

Arizona has experienced several produce-linked Shigella outbreaks, with berries—including strawberries, raspberries, and blueberries—identified as common vehicles for contamination. The FDA and CDC have investigated multistate Shigella illnesses traced to fresh produce distributed through Arizona retailers and farmer's markets. Contamination typically occurs at harvest, during packing, or through cross-contamination during transport. The Arizona Department of Health Services (ADHS) works with local county health departments to identify cases, trace supply chains, and issue public health alerts when outbreaks are confirmed.

How Phoenix Health Departments Respond to Shigella Alerts

When a Shigella outbreak is suspected, the Maricopa County Department of Public Health and ADHS coordinate investigations with the FDA and CDC. Health departments conduct epidemiological interviews with ill persons to identify common food sources, then work backward through distribution channels to pinpoint contaminated products and implicated growers. Quarantine and recalls are issued through the FDA's official channels, and public health advisories are released to healthcare providers and the media. Real-time monitoring of these agencies is critical—delays in consumer awareness can mean more exposures.

Consumer Safety Tips & Real-Time Protection

Wash berries thoroughly under running water just before eating, even pre-packaged varieties; use a soft brush for firmer berries. Purchase from reputable retailers with strong traceability practices, and check FDA.gov and FSIS recall databases regularly for active alerts. Store berries at 40°F or below and discard any that show mold or soft spots.
