Or you could just use 'grep -s'.
From 'man grep':

       -s, --no-messages
              Suppress  error  messages  about   nonexistent   or
              unreadable  files.   Portability  note:  unlike GNU
              grep, traditional grep did not conform to  POSIX.2,
              because traditional grep lacked a -q option and its
              -s option behaved like GNU grep's -q option.  Shell
              scripts intended to be portable to traditional grep
              should avoid both -q and  -s  and  should  redirect
              output to /dev/null instead.

grep-aholics might also be interested in:

       -r, --recursive
              Read  all  files under each directory, recursively;
              this is equivalent to the -d recurse option.

I used to always use find -exec grep {} \; until I switched to 
GNU grep 2+, which has the -r option.
