Australia mushroom poisoning: how a family lunch ended in tragedy

In late July, four relatives attended a family lunch at the home of Erin Patterson, a 48 year-old mother of two from Leongatha in Australia. Within days of the lunch, three of the guests were dead, with a fourth left fighting for his life in hospital. A beef wellington that was served for lunch on the day is suspected to have contained poisonous death cap mushrooms. But why were they in there? Australian police must now decipher whether it was simply a tragic accident or if there is something more sinister at play? John Ferguson of The Australian explains the details of the case.This episode was originally published in August 2023. In November, Erin Patterson was charged by Australian Police with three counts of murder and five counts of attempted murder. Her trial will take place in 2024.
All four guests were admitted to hospital the next day with poisoning from death cap mushrooms, also known as amanita phalloides, that were added to the beef and pastry dish.
Mr Wilkinson survived after a liver transplant.
Erin Patterson's husband, Simon Patterson (50) was also invited to the lunch but declined.
The jury was told on Tuesday that prosecutors had dropped three charges that Erin Patterson had attempted to murder her husband, whom she had been separated from since 2015.
Two weeks before the poisoning, Erin Patterson had invited her husband and his relatives to lunch while she was attending a Korumburra Baptist Church service where Mr Wilkinson was the pastor.
Simon Patterson initially accepted the invitation.
'She said the purpose of the lunch was to discuss some medical issues that she had and to get advice about how to break it to the kids,' Ms Rogers said.
'The accused said that it was important that the children were not present for the lunch,' Ms Rogers said.
The Wilkinsons were surprised by the invitation because they had never been to Erin Patterson's large five-bedroom house.
When Heather Wilkinson was taken to hospital the next morning, she told Simon Patterson she had been puzzled by Erin Patterson eating from a different plate than those served to the guests.
'I noticed that Erin put her food on a different plate to us. Her plate had colours on it. I wondered why that was. I've puzzled about it since lunch,' said Heather Wilkinson, according to the prosecution.
Simon Patterson told his aunt that his wife might have run out of plates.
Ms Rogers told the jury that Erin Patterson fabricated an ovarian cancer diagnosis to explain why her children did not attend the lunch.
'After the lunch, the accused announced that she had cancer and asked for advice on whether to tell the children or to keep it from them,' Ms Rogers said.
'They had a discussion about it being best to be honest with the children. They prayed as a group for the accused's health and wisdom in relation to telling the children,' Ms Rogers said.
Defence lawyer Colin Mandy told the jury his client never had cancer and that the guests had been poisoned by mushrooms she had served, but that the poisoning was accidental.
'The defence case is what happened was a tragedy. A terrible accident,' Mr Mandy said.
Ms Rogers told the jurors that she would not provide a motive for the poisonings.
'You might be wondering now why would the accused do this? What is the motive? You might still be wondering this at the end of this trial,' Ms Rogers said.
'You do not have to be satisfied what the motive was or even that there was a motive.'
Two days after the lunch, Erin Patterson went to hospital complaining of diarrhoea and nausea.
By then, medical staff had diagnosed her guests as suffering death cap poisoning.
Erin Patterson told authorities that she had cooked with a mixture of fresh mushrooms bought from a supermarket and dried mushrooms bought from an Asian food store.
Mr Mandy said his client had lied to police when she said she had not foraged for wild mushrooms.
'She did forage for mushrooms. Just so that we make that clear, she denies that she ever deliberately sought out death cap mushrooms,' Mr Mandy said.
Doctors insisted that Erin Patterson's two children, then aged nine and 14, be tested because their mother said they had eaten beef Wellington leftovers.
Erin Patterson said the children were safe because she had scraped the pastry and mushrooms from the steak.
She explained the children did not like mushrooms.
'The accused became teary and said she didn't want to involve the kids,' Ms Rogers said.
'She did not appear to be concerned so much about the children's health, but rather about stressing them out,' Ms Rogers said.
Ms Rogers said Erin Patterson had not eaten poisonous mushrooms and had not fed her children the lunch leftovers.
Health authorities treated the poisonings as an isolated incident and no mushrooms were recalled, the prosecutor said.
The trial is expected to continue for six weeks.
Erin Patterson is charged with three counts of murder and one of attempted murder.
Murder carries a maximum penalty of life imprisonment and attempted murder carries a maximum 25 years in prison. − AP
