The lab report is negative for the Sydney pub accused of serving a family faeces-laced gelato, the hotel says.
The Coogee Bay Hotel, which is accused of serving a family gelato laced with frozen faeces, says laboratory tests on an ice-cream tub has failed a find any excrement.
Meanwhile, staff at the hotel have all agreed to a DNA test in its efforts to clear the pub's name.
The Whyte family from Queens Park claim they were served contaminated ice-cream free-of-charge on October 5 after complaining they could not hear the televised NRL grand final over the pub's loud music.
The Whytes say independent testing commissioned by them found the dessert contained "properties similar to human excreta".
The NSW Food Authority is investigating the matter.
The eastern Sydney hotel today said its lab tests on the chocolate gelato tub had found no contamination.
"Laboratory testing of the ice-cream tub was returned today and shows no faecal contamination," a brief statement from the hotel said.
All staff, including then head chef Adam Wood, had offered to be DNA tested if required, the hotel said.
Dismissing the test and the staff's DNA promise as stunts, Whyte family lawyer Steven Lewis said the hotel should just apologise for the dodgy dessert.
The hotel's test on the ice-cream tub was irrelevant because "Mr and Mrs Whyte had a test of what was in her mouth", he said.
"What the hotel is testing is what happens to be in their fridge." But following the hotel's lead, he said both Stephen and Jessica Whyte had offered to undergo DNA testing, to quash any suspicion of sabotage.
"It is a stunt by the hotel, but not withstanding, Mr and Mrs Whyte will agree to give a DNA sample," Mr Lewis said.
"There is nothing to suggest the staff on duty that night were responsible for putting the faeces in the ice-cream - it was frozen.
"What are they going to do? DNA test their staff going back a year."
The allegations, first aired on the weekend, have triggered a storm of claim and counter-claim between the Whytes and hotel.
The hotel's management has accused the Whytes of demanding $1 million "shut-up money", a claim the family vigorously denies.
The scandal was further muddied by revelations Mr Whyte's brother-in-law was marketing manager for Keystone Hospitality, owner of Sydney's Cargo Bar and Bungalow 8.
Ms Whyte said she thought a staff member was behind the incident and urged the pub to release CCTV footage.
In its statement, the hotel said it was "very keen" for the footage to be released, but said it had been advised against doing so by the Food Authority.
However, the footage showed restaurant manager Cherilyn Kennedy had not served the ice-cream, as had been reported, the hotel said.
The hotel also confirmed chef Adam Wood resigned prior to the Whyte family incident.
He was due to finish at the end of September, but temporarily stayed on to help out the newly re-launched restaurant.
"Contrary to media reports today, executive chef Adam Wood did not resign over the Whyte's alleged incident," the statement said.
"He tendered his resignation three weeks before and as a goodwill gesture agreed to stay on throughout the re-launch period until the 17th October 2008.
"Adam has left the hotel on good terms."
