Why Fish and Green Onion Can Be Risky
It might sound odd, but mixing green onions with fish — especially raw or lightly cooked — can pose a higher risk of food poisoning. Why? Green onions can harbor bacteria if not cleaned thoroughly, and when combined with fish proteins (particularly those in oily varieties), it may create a breeding ground for harmful microbes if not handled properly. The risk increases in warm environments or when freshness is compromised.
The Bacteria Reaction Explained
| Ingredient | Risk Factor | Resulting Issue |
|---|---|---|
| Green Onion | May carry soil-borne bacteria if underwashed | Increases contamination risk when raw |
| Fish (especially raw or oily types) | Highly sensitive to bacterial activity | Can cause food poisoning symptoms if contaminated |
Popular Dishes That Deserve Caution
Some of our favorite fish dishes might be hiding this risky duo. Here are a few examples where extra care should be taken:

Food Hygiene Tips for Fish and Veg
| Practice | Reason |
|---|---|
| Wash green onions thoroughly under running water | Removes soil and bacterial residue |

Final Thoughts on Cooking Smart
Love fish? Love green onions? Here’s how to keep them in your meals without the food safety fear:
- Always cook green onions when serving with fish
- Use alternative toppings like citrus zest or cooked garlic
- Keep fish cold until ready to cook
