Tiny White Worms Inside Cherry Tomatoes?

I have found tiny white worms living inside my cherry tomatoes. The tomato looks perfect from the outside, but when you cut it in half you can see it moving around in all of my tomatoes. I haven't noticed them until yesterday so I have been eating these things, what are they? Are they harmful? And how do I get rid of these things? I am so grossed out. Please help!
