A food dehydrator is under the spotlight in relation to an alleged mushroom poisoning in Victoria.

Three people are dead and another is in critical condition in hospital awaiting a liver transplant after eating the deadly lunch.

A former daughter-in-law of some of the victims made the lunch, and is now being investigated.

Australian correspondent Murray Olds says the dehydrator is among the latest developments.

"They found one at a tip not too far from Leongatha, where the deadly lunch was served up. Now it's undergoing forensic examination."
