I one read an article which said that you should never eat bar snacks (peanuts pretzels etc left for general consumption on a bar) because they were likely to contain large traces of urine from people (mainly men) dipping into them after using the lavatory. Perhaps K.P. could use it an advertising campaign.

I am aghast at the number of people who do not wash their hands, but more worried about attitudes to public health in general. We are in the midst of a flu epidemic, but people are under pressure to return to work when they are still likely to spread the disease to others, and it is positively frowned upon to take time off to visit the doctor's - world's gone mad.
