The doctor tells the court:

One of the types, she said, came from the supermarket with plastic over the top. The other pack she said she got from an Asian food shop a number of weeks prior.

She said they were in a packet but she’d opened the packet and put them in a container.

She said she couldn’t remember but perhaps if she drove past the shop she could recognise it.

She did say they had a strong smell.

I said I was trying to make sure there was no public health issue.

She told me that she came because her children needed to be checked out because there’d been a lunch and there was concern that they may also be infected.

She said that she had given the children some of the meal the following day but had scraped off the mushroom paste.

She told me she had made a beef wellington and she had made the beef wellington with a mushroom paste.
