NBC is running from its reality show "Ultimate Slip 'N Slide" ... after a bunch of folks on the crew experienced explosive runs themselves.
The network put the show on ice after members of the production staff experienced diarrhea ... apparently from some sort of parasite called Giardia.
The show was being shot in the San Fernando Valley and almost reached the finish line with 1 week of production left, but it was too much. After multiple crew members got sick, production was indefinitely shut down.
Neither of the hosts -- Bobby Moynihan and Ron Funches -- came down with the runs.
An environmental lab tested the water used in the competition, along with restrooms and other facilities, and initially results came back negative, but they got a positive result last month. So, with 7 weeks in the can (sorry) and one week left to go, the door was slammed shut ... this according to PEOPLE.
The show was set to premiere August 8 after the closing ceremony of the Olympic Summer Games.
