E. Coli in Romaine Lettuce: San Diego's Food Safety Guide

Romaine Lettuce E. Coli Outbreaks & San Diego's History

E. coli O157:H7 contamination in romaine lettuce has caused multi-state outbreaks tracked by the CDC and FDA, with California—including San Diego County—experiencing significant cases. The 2018 and 2019 outbreaks highlighted how contamination typically originates in growing regions, often traced to contaminated irrigation water or soil. San Diego County Health and Human Services Department (HHSD) has documented cases during these periods, coordinating with the California Department of Public Health (CDPH) and FDA to identify contaminated sources. Shiga toxin-producing E. coli (STEC) can cause severe hemolytic uremic syndrome (HUS), particularly in children and elderly populations.

How San Diego Health Departments Respond to Contamination

The San Diego County HHSD Environmental Health Division works directly with the FDA's San Diego District Office to investigate contamination sources and issue public health alerts. When contaminated produce is identified, rapid communication goes to hospitals, healthcare providers, and retailers through official channels. The County Disease Control and Prevention Branch epidemiologists track case clusters, interview patients about food sources, and coordinate traceback investigations with the FDA. Local restaurants and food service facilities receive compliance alerts, and HHSD inspectors may increase monitoring at establishments serving affected products. Real-time coordination with state and federal agencies ensures swift removal of contaminated stock from San Diego retailers.
