Ophidascaris robertsi is a roundworm usually found in pythons. The Canberra hospital patient marks the world-first case of the parasite being found in humans.

The patient resides near a lake area inhabited by carpet pythons. Despite no direct snake contact, she often collected native grasses, including warrigal greens, from around the lake to use in cooking, Senanayake said.

The doctors and scientists involved in her case hypothesise that a python may have shed the parasite via its faeces into the grass. They believe the patient was probably infected with the parasite directly from touching the native grass or after eating the greens.

Moral of the story: make sure you wash all the snake shit off your produce and hands before eating.
