I wouldn't just arbitrarily throw anything out, but would go a few extra lengths to ensure proper sanitization. I would soak and scrub everything in PBW very well, then soak overnight in StarSan. Make sure you are properly measuring the StarSan and not just dumping a bunch of concentrate in water. No sense in wasting it, but you have to make sure the concentration is correct so the PH is low enough to kill the nasties.
