Think about the thousands of years beer has been brewed. Now think of only the couple hundred years we have known about germs. Beer has been brewed in woods and plains and deserts without soap, without star-san or iodophor. In spidery, mildewy scary trappist cellars (sours or not). I tend to think most people over concern themselves with sanitation. Sure, you want things to be clean and do what you can to avoid contamination, but as long as you didn't just scratch your ass with said spoon, *personally* I wouldn't lose any sleep over it.
