blackberries--tiny thready white worms

Someone else told me her blackberries had little worms in them, so I looked in mine, and I found 1 or 2 tiny, thready white worms squirming in the core of some (not all) berries. I looked only in ripe berries. They don't look like any of the economic pests listed for berries, but they're so tiny it's hard to tell what they are. I think I may have seen similar tiny wormy creatures in damaged strawberries. Does anyone know what they are? And what (if anything) to do about them in an organic garden?

Very likely fruit fly larvae. I have some in my blackberries every year, and there are certainly fruit flies around the berry patch.

The yellow sticky cards might catch a few adult flies; keep fallen fruit picked up. Promptly refrigerating/freezing berries can prevent more larvae from hatching, otherwise pick/rinse larvae off of harvested fruit. Chilling seems to bring them to the berry surface.

RE: blackberries--tiny thready white worms

I have the same little white worms in the center of some of my California blackberries. I noticed them last year and they are back this year. I have not noticed any fruit flies around the plants. Is there some way to get rid of them and is the fruit edible?
