The New York Post reports that workers at the trendy Manhattan restaurant, Freemans, were forced to hand over stool samples to the Department of Health — after a pregnant customer reported she contracted a foodborne illness at the eatery.

The Lower East Side brunch hot-spot — which boasts celebrity clients and hour-long waits — was investigated for an outbreak of norovirus, a Department of Health spokesman said.

During the probe, workers were asked to do their business in a cup to prove they were free of the virus, which causes vomiting and diarrhea sources said.

“They came and checked everything yesterday…They tested everyone… [They took] stool samples,” a worker told The Post with a sheepish grin on Thursday.

The virus is contracted through fecal matter and person-to-person contact and effects roughly 20 million people every year.

A spokesman for the restaurant claimed the health department found no sign of norovirus.

“The Dept of Health did look into this at Freemans and have concluded their findings and ended their investigation and found no link or transmission of any kind at the restaurant,” said restaurant rep Eden Grimaldi.

“Freemans remains open, with an A rating,” Grimaldi added.
