On two recent occasions in the last week, a reader found a worm in her toilet. She found the worm after she used and flushed the toilet in both instances. The worm in the toilet is quite small – it is only about a half an inch long (about 1.5 centimeters) – and it has a white and grey body. (It isn’t really either color, so the worm is more of a whitish, grayish color, with both end tips of the worm being a darker, almost black color.) Understandably, the reader was worried about finding a worm in her toilet, so she went to the doctor to be tested for parasites. She was given Albenza by the doctor as she awaited her test results. In the meantime, she asked us to weigh in the matter, hoping that we can identify the small worm in the toilet she found.
