Those white wiggling things are most likely tiny insect larvae that were hiding on or inside the berries. This can happen with fresh berries, especially softer fruits like raspberries, blackberries, and strawberries. A salt-water soak can make some small larvae come out, which is why people sometimes notice them afterward.
Should you throw the berries away?
- If the sight of larvae makes you uncomfortable: It’s perfectly reasonable to discard them.
- If the berries are fresh and you want to keep them: You can rinse them thoroughly under cool running water, remove any damaged or moldy berries, and eat them soon or cook them.
A few larvae in fresh produce are unpleasant, but they don’t automatically mean the entire batch is unsafe. The bigger concerns are:
- Mold
- Fermented or sour smell
- Slimy texture
- Spoiled or leaking berries
For next time:
- Rinse berries just before eating (washing too early can make them spoil faster).
- Store them dry in the refrigerator.
- Inspect and remove soft or damaged berries.
If you tell me which berries you soaked (strawberries, raspberries, blueberries, blackberries, etc.), I can tell you what those larvae most likely were and how common they are.
