potentially carry bacteria such as Salmonella, E. coli, or Listeria.
The important point is that the vegetable itself isn’t inherently “dirty.” The risk comes from contamination and from what happens between the farm and your plate.
Because raw green onions are not heated before eating, any harmful microorganisms present on the surface may remain there.
What Could Happen If Contaminated Produce Is Eaten?
Foodborne illness can cause symptoms such as:
- Nausea
- Vomiting
- Diarrhea
- Stomach cramps
- Fever
For most healthy adults, foodborne illnesses are usually temporary. However, certain people—including young children, older adults, pregnant women, and people with weakened immune systems—can face a greater risk of serious complications.
That is why proper food handling matters.
How to Wash Green Onions Properly
One of the easiest ways to reduce the risk is to wash green onions thoroughly before eating them.
Start by removing damaged or wilted outer portions and trimming the roots.
