You will be fine. Yes, Star San will shine copper up nicely. It might have pulled some oxalate off of the copper. This will not harm you. The metallic odor could be many things. It is probably the star san cleaning the copper. This is not toxic.

Subject: Star San and Copper safety?
Last night I was bottling some homebrew and I had a tub of star san for sanitizing bottles and hoses. While I was siphoning into the bottling bucket I left the copper hose connector from the spigot soaking in the star san for about 10 or 15 minutes. After I removed it from the star san it was a bright copper colour (like a shiny new penny). I then reassembled the bottling bucket spigot and proceeded to bottle, giving every bottle a quick star san rinse immediately before filling. When I was done I noticed the star san had a slight metallic odour and when cleaning up I noticed that the copper hose connector had the same odour (but much stronger) as did my hands after touching it. Did I leach copper or some other toxic compound into the star san? Did I then contaminate every bottle with the final rinse before bottling? I didn't notice any change in Star San colour but it could have been missed due to that suds. I've heard about yeast precipitating out metals, but this is a hefeweizen and we will be drinking the yeast. Should this be something I concern myself with (and dump the batch) or am I over reacting?
I appreciate any feedback you can give. Thanks,
