I've been thinking about using fresh silt from a creek that runs through my property as a fertilizer for my fruit and vegetable garden. Is this a good idea? What should I test for before using it? Also, would solarizing the silt be sufficient to eliminate any harmful bacteria?

I wonder if harmful bacteria are really a concern? It seems like moving it might end up being more hassle than it's worth. But if you're worried, testing it would be a good idea. I mean, bacteria are pretty much everywhere, especially if you're using creek water for your plants anyway! Personally, I have access to about 10 yards of nice topsoil each year which saves me a lot since I deal with clay soil.
Before you scoop up that silt, check your local laws. Taking materials from a creek can sometimes get you into trouble without proper permission. Also, keep in mind that solarizing can kill not just harmful bacteria but beneficial microbes as well, so you might end up losing out on its good properties.
I actually dig out silt from my ponds whenever they dry up. I mix it with organic debris and it works wonders for my garden beds. Just be aware that you might be introducing weeds from upstream! Overall, I find it enriches my soil and reduces the amount of commercial fertilizer I need to buy, which is a big plus!
That’s awesome! Do you have any pics of your garden? It sounds like you're really making the most of it!
