The luxury Melbourne hotel at the centre of a salmonella outbreak is working "day and night" to resolve the issue.
Twenty-three confirmed cases of salmonella poisoning have now been linked to high tea at The Langham on July 11 and 12, with 66 people becoming ill and 14 of them admitted to hospital.
Results from the hotel's food samples are still days away, but since there have been no new cases, the bacteria is likely no longer there, Victorian Health Department spokesman Bram Alexander says.
But the number of confirmed cases could increase, with more diners expected to come forward.
The Langham managing director Ben Sington said news reports that the hotel had been fined or failed health inspections in the past were untrue.
"In February 2014 it was asked to make improvements, which it immediately did," Mr Sington said in a statement on Thursday.
"The hotel was duly inspected in March 2014, receiving a complete bill of health."
He said that 2014 request was unrelated to the current situation, which the hotel was working "day and night to resolve".
The hotel had worked closely with authorities, cleaning its kitchen and removing suspected contaminated food, Mr Alexander said.
"Because of the work done to clean up the kitchen, it's probably one of the best places to eat because it's one of the cleanest," Mr Alexander told AAP on Thursday.
A pregnant woman celebrating her baby shower was among those struck down, with doctors delivering her baby five weeks early.
The newborn suffered breathing problems as a result of a traumatic birth.
