Considering the overall topography of the area, this is hardly either
surprising or shocking. Examine, for instance, the standard procedure
for obtaining urine samples from men for bacteriological purposes 
(careful washing followed by "mid-stream" sampling, and yet commonly
~1000 bacteria/ml are found in healthy individuals). In your case a
"mid-stream" sample is probably out of the question...
