Mr Mandy is now showing images of toxicology results from the testing of the samples.
Each sample is labelled, such as "beef" or "pastry", but Dr Gerostamoulos agrees that there could be elements of other items in the contents. For example, the "beef" sample may contain small amounts of pastry.
There is also discussion of a "confidence threshold" for each sample. Mr Mandy asks whether that means there could be a smaller amount of that substance which does not reach the threshold.
Dr Gerostamoulos says "there may be" and explains that food analysis "can be challenging."
