For the OP's benefit, I'll make this explicit:

chomp; basically removes from $_ a terminating string equivalent to $\; chomp $foo; does the same, but to $foo rather than $_. See perldoc -f chomp.

However, you have no use for chomp here. You're getting "rows" of data which has been parsed for you and are now hashrefs, not strings!
