Nigel, in your clip you pointed out:

When the ban was introduced, officials were keen that food manufacturers should focus on overall hygiene rather than relying on a single chemical decontamination step to eliminate microorganisms.

That is partially food safety, but also an overall approach to hygiene, namely be hygienic at every step, rather than not care too much but tey to sort it just as the food leaves the door.

I would readily admit we are not exactly great at that, but it is not simply a question of whether the food is safe in the end.
