As someone who works in a dairy manufacturing facility, you really aren’t making sense.
You’re describing fairly straightforward industrial processes.
There is bacterial growth in every single food manufacturing facility in the world. It’s unavoidable.
That’s why there is constant, and I mean constant cleaning. Stainless steel or silicon are used for any surfaces that the product touches, there is a TON of QA testing done specifically for allergens and bacteria. All factories are held to regulatory standards, I can’t imagine this operation would be any less safe and compliant.
Be careful when dual booting. I’ve had to manually rebuild my partition tables way too many times because Windows doesn’t like to play nice. That was dual booting from the same disk though so ymmv with a dedicated nvme.
