What Are the White Wiggling Things?
In many cases, the tiny white creatures are fruit fly larvae, particularly those of the spotted wing drosophila, a small fruit fly species that lays its eggs inside ripening fruit.Insects & Entomology
Unlike many other fruit flies that prefer damaged or overripe fruit, spotted wing drosophila females have a specialized egg-laying organ that allows them to pierce healthy, ripening berries.
The eggs hatch into tiny larvae that feed inside the fruit.
These larvae are usually:
White or cream-colored
Very small (only a few millimeters long)
Difficult to notice without close inspection
When exposed to salt water, changes in the environment may encourage some larvae to emerge from the fruit.Water & Marine Sciences
Why You Usually Don’t Notice Them
The truth is that fresh fruits and vegetables grow outdoors.
Even with modern farming methods, it’s impossible to completely eliminate insects from agricultural fields.
Farmers work hard to reduce pest damage through monitoring, crop management, and approved pest-control methods, but nature cannot be entirely controlled.
Many insects are harmless visitors to fruit crops.
Others occasionally lay eggs inside fruit before harvest.
Because larvae are so tiny, consumers rarely notice them during normal eating.Insects & Entomology
Does This Mean the Fruit Is Unsafe?
Finding larvae can certainly be unpleasant.
However, in most cases, their presence does not automatically mean the berries are unsafe to eat.
Food safety experts generally distinguish between:
Natural insect contamination.
Harmful bacterial contamination.
Mold growth.
Chemical contamination.
Fresh produce naturally contains tiny amounts of insects or insect fragments simply because it is grown outdoors.Produce
Food safety regulations in many countries recognize that eliminating every insect from fresh produce is not realistically possible.
