Tomato plants: safe or not?

Earlier this year, we had a break in the sewer line from our house, and there was a bit of leakage in the flowerbed out front.

It’s all been repaired now, and there’s no problem.

However, we also now have a dozen tomato plants coming up in the near vicinity of the pipe. We’ve never grown tomatoes there.

We know that tomato seeds are hardy things, that tomato plants thrive in sewage treatment plants, and that natural fertilizers are, um, natural.

The question is whether anything bad that might have leached out of the pipes three months ago, before the repair was made, could have a detrimental effect on tomatoes that have not yet blossomed or formed. Assuming that we don’t mind having tomatoes in the front yard, will they be safe to eat?

Should we let them grow, take them out, or transplant them elsewhere?
