Actually with BARF you should give also some vegetables to your dog. And good BARF food has the same things as you mentioned e.g. cow stomach with greens inside it (dunno it's English name) As for worms..you should always give your dog anti worm pills, he/she is always up to no good, e.g. drinking from puddles. Also buy quality barf food.

The person you are responding to is talking about hard to detect parasites, not just worms. Given that they are hard to detect, I don't think it is reasonable to assume that buying "quality barf food" will solve this issue.
