Sounds like bacterial spot or similar. Is there something about it in the FAQ?

My experience has been Hole in Tomato = Worm in Tomato.

When I'm picking tomatoes, I throw away any with holes. I have had the unpleasant experience of cutting into a tomato with a big, nasty worm inside (not noticing the hole). YUCK!

Tomato fruitworms (aka corn ear worms). The larvae of a moth that bore into the fruit while quite small and then live inside the worm as they mature. BT (Dipel) dust is an effective and organic control for them. These are NOT the same thing as tomato hornworms but are often confused with each other.

Here is a link that might be useful: Tomato Fruitworms

Birds make holes sometimes. They are usually deeper than wide but not always. I even found a box turtle eating at a low growing fruit. A friend has problems with squirrels

You can test it by placing screens around the tomatoes (plants or individual fruits) that would prevent some pests.

Question: I'm hesitant to throw my wormy tomatoes in the compost heap for fear that the larvae will somehow infest my compost and be carried into my garden later. Is it better to dispose of the infested tomatoes away from my compost/garden?

I found a couple tomatoes crawling iwth teeny tiny baby slugs. ICK! They left small holes behind...

lisalu, would the temps inside the compost heap kill the worms? It can get pretty hot in the middle. Even if the worms weren't completely wiped out, would their eggs be viable under those conditions? Might they even be helpful (breaking down organic matter, etc.)? I'm not sure myself...my only experiment with active composting didn't work out so well. Just food for thought, I guess.

We had some ugly brownish/grayish caterpillars in our tomatoes this weekend (BIG YUCK!!) I don't know what kind they were but they were much uglier than even the cornworms. I lost 4 huge (over a pound each) oxhearts to them. WAAAH
