Toxic neckties?

This story caught my eye – guess I’ll think about dry-cleaning my ties from now on:

A small study of neckties worn by doctors at a Queens hospital found almost half the 42 ties tested harbored microorganisms that can cause illness.

Of the 42 physician neckties sampled, 20 contained one or more microorganisms known to cause disease, including 12 that carried Staphylococcus aureus, five a gram negative bacteria, one that carried aspergillus and two ties that carried multiple pathogens.
