What you likely saw is tiny insect larvae (often fruit fly larvae or similar pests). This can happen with berries because they grow close to the ground and have soft skins that insects can lay eggs on before harvesting.
đź§ Why they came out in salt water
Soaking berries in salt water doesn’t create anything—it just:
- Makes hidden larvae or insects come out of the fruit
- Reveals contamination that was already there
So yes, the “white wiggling things” are almost certainly pre-existing insects, not something caused by the salt water.
🍓 Should you throw them away?
✔️ Safe to keep (with cleaning) if:
- The berries are otherwise firm and not moldy
- Only a few larvae were seen
- You rinse them thoroughly after salt soaking
❌ Better to discard if:
- You see many larvae repeatedly
- There is mold, bad smell, or mushy texture
- You feel uncomfortable eating them (food safety also includes comfort)
đź§Ľ How to clean berries properly
If you choose to keep them:
- Mix water + salt (or vinegar solution)
- Soak 10–15 minutes
- You’ll see insects come out
- Rinse thoroughly under running water
- Pat dry and refrigerate
⚠️ Health risk?
In most cases:
- Accidentally eating a few fruit fly larvae is not dangerous
- The main issue is hygiene and disgust, not toxicity
đź§ Bottom line
It’s common in fresh berries. If it looks mild, cleaning is fine. If it looks heavily infested or you feel uneasy, discarding them is the safer choice.
If you want, tell me what type of berries they were (strawberries, blueberries, etc.), and I can tell you how likely this is to happen and how to prevent it next time.
