I have been following Hulda's suggestions in her book and
passied tape worms and small rounds worms. Today I passed
a round worm that was about 18 in. long. What could that
be? Thanks for responses. Bev
I belive this 18 inch worm you passed is called the "large roundworm." I have passed many of these worms that were atleast 1 foot and longer. In my book, "Guess What Came to Dinner", it says this is the most common intestinal parasite. The worm resembles the common earthworm in appearance.
