The levels of lead in the eggs that were so high, if a child was to regularly eat one or two of them, they could become severely cognitively impaired.
That was the sort of shooting gun for me that really got me interested in this. And as part of my reporting, I went down to Wales on a number of occasions and truly just knocked on people's doors and tried to get a sense and a feel as to whether or not the farmers or the people living in these parts of Wales near old lead mines, which I found on maps, had ever experienced anything like Horse's 9. And it became very clear to me very quickly that yes, actually, there were people who reported a number of things from animals dying to not being able to grow vegetables.
And in the most severe case I found, I found a mother whose daughter's gums actually turned green. She went to the doctor and the doctor identified lead poisoning and that really was the start of it. And I, this has been a very long story, I will stop here. But I was initially interested in why animals were dying and then it's moved considerably into looking at food and then obviously the most important thing for me has been trying to understand the impact of this on people.
