TBH I wouldn't do it - there's been so much out there that suggests that the same part of the immune system that responds to worms has now been made redundant (due to us eliminating them) and so has shifted its attention to other things, like severe allergies and Inflammatory Bowel Diseases.
I'd leave it, unless you actually suspect worms.
Yep, I've read that too. Funny to think that worms could actually be good for us....
