Aluminum foil in my food!?

Help, I made some pasta salad the other night and covered it with foil. Today I looked and there were tiny little holes in the top of the foil. I didn't think much of it (I thought they were coffee grounds my mom had spilled, they looked like little black spots.) I ate some today but I thought it was kind of dry, so just now I went to add more sauce to it..and I noticed something. There were some aluminum foil flecks in the pasta. Also, it seems that some foil had rubbed off on the noodles.. like I don't know, some noodles had a silver coloration to them. It seems like it was just a few noodles and veggies on the surface and I spot-removed the noodles that looked like they had a problem, but now I'm worried. What if I ate some of the tainted noodles without noticing before? What if there' still some aluminum lurking in my pasta? :( Has anyone had this problem before?
