Onions Recall History: Tracking Contamination Risks & Outbreaks

Common Reasons for Onions Recalls

Salmonella contamination is by far the most frequent reason for onion recalls in the U.S., accounting for the majority of enforcement actions by the FDA and state health departments. Unlike leafy greens or berries that can be contaminated post-harvest, onions are typically contaminated in the field through contaminated irrigation water, soil, or animal contact. Secondary pathogens like E. coli and Listeria monocytogenes have also triggered recalls, though less frequently. Mold and aflatoxin contamination can occur during storage when humidity and temperature conditions are not properly controlled.

Notable Onion Outbreaks & Seasonal Patterns

The largest onion-associated Salmonella outbreak in recent history sickened hundreds of people across multiple states, prompting FDA investigations into growing operations and supplier networks. Outbreaks tend to cluster in summer and early fall months (July–October) when onions are harvested and distributed fresh, though storage onions from earlier harvests can pose risks year-round. Texas, California, and Washington are major onion-producing states, and import sources—particularly from Mexico and Peru—have been implicated in several multistate outbreaks. The CDC epidemiologically links illness clusters to specific farms and distributors, working with FDA to issue recalls and conduct traceback investigations.
