European E. coli Outbreak from Sprouts (2011)
A deadly E. coli outbreak in Germany sickened over 4,000 people and killed 53, ultimately traced to fenugreek seeds used to grow sprouts. Authorities initially misidentified the source, and the investigation took weeks.
The recall of sprout seeds across Europe halted sales and led to widespread public caution about raw sprouts.
The outbreak prompted tighter testing protocols for seed lots and highlighted the risk of sprout cultivation where contamination can multiply rapidly.
Sprout seeds are a known vector for bacterial contamination because the warm, moist conditions used to germinate them also allow pathogens like salmonella to thrive. This recall underscores that even raw seeds carry risk and require rigorous screening.
