Bash shell unwanted file expansion at the space character

I'm trying to process a bunch of subdirectories that have spaces in the name.
The following bash script is expanding $thisfile at the space, so the file command fails as it never gets the full path/filename
How can this be fixed.

Oddly,
  echo $thisfile
does not expand $thisfile

Thanks

==============================
find . -print | while read thisfile
do
file $thisfile
done
