When I run the code I showed, I get different output:

use Data::Dumper;
my %SeqRec = (foo => 'bar');

print ("content of hash is " . Dumper \%SeqRec);

content of hash is $VAR1 = {
          'foo' => 'bar'
        };

Your output is at least missing the closing bracket. If you want to debug this, please show the full code you're running.
