The toxicologist explains the testing of the fatal beef -wellington -lunch to Erin Patterson Mord Trial

The defenders of the accused murderer Erin Patterson have proposed that a person could survive the fatalities poisoning for the death of death, even after eating the same food as someone who got seriously ill.

Ms. Patterson is accused of having murdered three relatives by serving them a beef -wellington food that contained toxic mushrooms for the death cap.

Ms. Patterson has not guilty.

Victoria's chief toxicologist Dimitri Gerostamoulos returned to the second certificate in the witness box on Friday, which was questioned by Colin Mandy SC of defense.

The defense provided Dr. Gerostamoulos in question about all factors that led to diseases caused by die mushrooms, and confirmed to the court that medical knowledge was based on animal studies.

“There are many variables that had to be taken into account for this fatal dose,” said Dr. Gerostamoulos, including age and health of the subject.

He said a fatal dose was 0.1 mg per kg body weight.

Mr. Mandy showed a study in which some people showed that mushrooms consumed the death limit, which reacted with different severity, which was divided into four classes.

He informed the court that in the first class one person may not develop liver or kidney problems, although they ate the same meal as people who reacted more.

The public prosecutor then set up a hypothetical scenario that two adults die the same amount of a meal with mushrooms with death caps and one of the adults.

The public prosecutor Sarah Lenthall asked Dr. Gerostamoulos, what would happen to the other person who had eaten the food.

Dr. Gerostamoulos informed the court that they would probably get seriously ill, but could survive, and quoted a case of 2024 when a Victorian man survived the fatalities of the fatalities after a stay in the intensive care unit.

Toxin test results shown in court

The Court was again led by tables in the laboratory tests, whereby the level of the toxins is present in rehearsals from each of the lunch guests.

Samples taken by Don Patterson and Ian Wilkinson tested positively for toxins that were found in the mortality cap.

However, rehearsals from Gail Patterson and Heather Wilkinson tested negatively for these toxins.

The four lunch break was all tested between 25 and 32 hours after lunch.

Two rehearsals were removed 51 hours after lunch by Erin Patterson and were not positively tested on death caps.

These were blood and serum samples, liquids that determined the defense that were faster than the urine toxin.

Ms. Patterson's children were also tested and not found in any of her systems.

Test found toxins in beef -wellington residues

Also on Friday, Dr. Gerostamoulos the process of extracting samples from remaining foods, which it is for a sometimes difficult but routine task for toxicologists.

In the tests, attempts were made to recognize toxins that are present in the death -cap mushroom, known as Alpha and Beta Amanitine.

On Thursday, he announced the court that Beta -Amanitine was found in rehearsals of mushroom paste and beef about a month after lunch on July 29.

The court heard that remnants of two different places in Erin Patterson's house were collected, but were placed in a pocket.

Dr. Gerostamoulos said it was not an ideal way to get the rehearsals.

The court also heard from a plant scientist who had analyzed the remains of lunch separately.

David Lovelock, who specializes in plant virology and bacteriology, told the court that he had used a technique that is known as DNA barcoding to test the lunch for the welling tone beef and the deficit of a dehydrator for food.

At the beginning of the trial, the court of Patterson heard both a black dehydrator for Sunbeam food bought and from, from which rehearsals were taken.

The tests in the dehydrator were more than 99 percent positive for the dying cap, but Dr. Lovelock has not found any evidence of the food on offer.

The attempt goes on.
