"We can't kid ourselves Jamie. We do actually slaughter animals, there's no nice way of saying it - that is what happens - and there is an element ... of people that think about their food like that."
Slater believed most people understood "the system" and how agriculture worked as they got older.
"I know that in the younger generation, the under 20s ... there is probably a larger element of that viewpoint but I think - without talking down to people like that - you mature as you get on in life and you understand how life works better and accept it."
"Of course that [viewpoint's] always going to be there, but I really don't believe it's one of those things that will mean the death knell ... of our industry - far from it."
Slater has been in the role for 27 years, and will end his tenure in the second half of 2021.
