sed in perlby GauCho (Initiate)

GauCho has asked for the wisdom of the Perl Monks concerning the following question:
Hi All, i have a problem with using sed in a perl script. Requirement: Read a csv file (file1) containing certain pattern, match the pattern in another text file (file2) and delete it where ever its occurring.
in the end only dad/fry = 000 should remain in file2.
I cannot install any package, so have to use the default perl options.
Since my file1 contains special character "/" , i have escaped it in my code.
my sed command is working fine if I try to run it without loop, i.e for one pattern only. As soon as I add it in loop, it fails.
The above works fine.
i tried to encorporate in a loop
error<c> sed: -e expression #1, char 10: extra characters after command sed: -e expression #1, char 0: no previous regular expression
