A family have claimed their children suffered hallucinations and ended up in hospital after a Perth café fed them brownies laced with marijuana.

The owner of Bada Bing Cafe has been charged by the local council after two young children and their mother ate the brownie.

The family claim they went to Woodlands café on March 2.

Afterwards, their five-year-old daughter Emily described things as “jumping” and her vision became impaired, they claimed.

After they went to hospital, Sharon began developing similar symptoms, while their three-year-old son Thomas was drowsy.

Tests showed Sharon and the two children all had traces of marijuana in their system, according to the ABC.

Michael, who did not eat the brownie or have any symptoms, said he returned to the cafe the next day and bought another brownie.

“(I) put it straight in the freezer and then a week or so later the police came and took that away,” he told ABC radio on Tuesday.

Analysis of one brownie confirmed the presence of THC and other cannabinoids, a spokeswoman for the City of Stirling council said.

Business owner Nathan Sharp, trading as Bada Bing Cafe, was charged by the council with two counts of selling food that was unsuitable on March 2 and 3.

He is due to face Perth Magistrates Court on July 19.

“We can assure our residents and the community that we have done a thorough investigation,” the council spokeswoman said.

“This appears to be an isolated incident and the city believes it has addressed any potential risk to the community.”

Proprietor Simona Sharp said the cafe had “co-operated with WA Police who had confirmed that their investigation has been completed and no charges would be laid” by police.

“It came as a total shock to us that a Perth family is alleging that they became ill after eating at our café,” Simona Sharp said in a statement.

“We of course have, and continue to fully investigate this allegation.
