Intestinal myiasis occurs when fly eggs or larvae that were previously deposited in food are ingested and survive in the gastrointestinal tract. Some infested patients are asymptomatic; others have abdominal pain, vomiting, and diarrhea. This is a case of 36 year old male farmer who presented with history of passage of worms in his stools. The patient also reported mild pain in abdomen, regular constipation and passage of flatus since last 15 years. These complaints had increased since last 3 months. On examining his multiple stool specimens plenty of cysts of Giardia intestinalis were seen. The larvae which were seen in this case were examined, and they were identified as larvae of “Sarcophaga spp. ”The patient probably ingested larvae of the fly by contaminated water or raw vegetables or fruits from his own farm. The present case report highlights the possibility that worms or larvae in stool can be of flies and these should be closely examined in case of such complaints. Though cases of intestinal myiasis are rare, these cases keep occuring in developing countries like India.
