Thanks everyone for your support and concern.
I'm actually going to see if I can get an assessment for neurodiversity. A few people have suggested I may be on the autism or ADHD spectra. Let's see... But one of the symptoms of either can be rigidity of thinking. And I cannot hammer it into my skull that there is room for a grey area on some of this.
Take the Quaker case in the US which I wasn't aware of (thanks Scampi I think who shared it.) I would be shooketh if they don't find somewhere down the line a QA Manager who can point to an audit saying "we raised this but were told we'd have to shut the plant too long / it would cost too much / we can't do it this year / it's still on the list and nobody has got back to me*"
* delete as applicable.
Pepsico own Quaker. This is their code of conduct:

"Acting with integrity is the right thing to do, and only makes our business stronger"
Or look at another of the biggest food companies in the world. Unilever. Who recently messed up their packaging and had a public recall?
Purpose, values & principles | Unilever
"Unilever is committed to providing branded products and services which consistently offer value in terms of price and quality, and which are safe for their intended use. Products and services will be accurately and properly labelled, advertised and communicated."
Now how did you end up with the wrong packaging if you resourced your systems to deliver on those aims... 
So is it my brain that's wrong or the food industry?
Perhaps we need something like "B Corp" a standard people could apply to "QFS Corp" if you will where there is a specified minimum percentage of profits which are put back into food safety and quality improvements? But it's so easy to ignore what needs to be done for years if you want.
I brought this up recently in our leadership team. The UK chilled food industry is full of plants which are 20, 25, 30 years old when chilled manufacturing exploded in the UK. Over the years the money hasn't gone into repair and maintenance every year. It's an easy thing to cut. Over time, drains fail. Walls fail, floors certainly fail. I've even seen some plants (mostly not chilled thankfully) with "rain catchers" to divert roof leaks. What is the plan to either really invest in these plants or build new?
