There is no worry with ANY* organisms on equipment that is small enough to be boiled. Hoses, taps, fittings, etc that can fit in a boil pot will be free of any contaminants after boiling. The problem comes with larger vessels that can't be boiled. Then you have to rely (hope) that a sanitizer can do its job.
* OK thermophylic organisms might not be eradicated through boiling, but they are not typically a problem in the brewery.
