Health authorities sanitized a Noosa cafe for five hours after an employee triggered a Hepatitis A alert.

Queensland Health is urging anyone who dined out or used the toilet at the Beach Chalet Shop at Sunrise Beach between October 10 and November 1 to see a doctor.

People can be vaccinated within two weeks of exposure to the virus to reduce the risk of developing Hepatitis A.

Despite the highly contagious nature of the disease, Beach Chalet Shop owner Ivan Mather said the whole thing had been blown out of proportion.

“This will blow over,” he said. “Because it is just ridiculous.”

Two days ago, Mr Mather said he was advised over the phone by a state nurse that the employee had contracted Hepatitis A.

The employee no longer works at the cafe.

Mr Mather said he voluntarily closed the shop.

“I want to make that clear. I did it voluntarily,” he said.

He said Noosa Council health department staff was satisfied the cafe could be re-opened for business.

“They were here for four to five hours, supervising and sanitizing,” he said.
