Supressing Errors in MARC::Record

I have a script that fetches MARC records from my library's holdings via Z39.50.  Every once in a while a record doesn't have a MARC Record attached to it and I get the following error:

Can't call method "rawdata" on an undefined value at zrss.pl line 47, <STDIN> line 1.

Here's what I have on and around line 47:

        #create new record object
        my $rec = $rs->record($i);  
        
        #read in raw MARC to record
        my $mrec = MARC::Record->new_from_usmarc($rec->rawdata());

I would just like to skip those items without records or suppress this error and just go on to the next record, is this possible? 

Thanks.
