Signs & Portents: Who is Mincing Your Meat?

Who is Mincing Your Meat?
What the hell is that supposed to mean? I drive past this sign several times a week and every time I see it I am more and more confused as to what the company are trying to infer.
Obviously they are purveyors of quality meat derivatives to the discerning customer. I understand that much.
But 'Who is mincing your meat'... why did they decide to have that emblazoned across a sign by the roadside at (what I assume must have been) some reasonable expense to themselves.

It seems quite innocent at first glance...but think about it they haven't said, 'is your meat being minced by people who adhere to industry standard hand hygiene regulations'. They said 'who is' not 'How is'. Are they inferring that a certain type of people are preferable as meat handlers. Which type of people are they talking about. Are they a bit racist?? Do they mean that my meat is guaranteed to have been minced only by stout hearted remain voters. Or only by conservative party members who can recount their ancestry back five generations, or only by good Catholics?

This question has been puzzling me for a while during my morning commute to work. I found myself humming a little tune about it which I have transcribed below for your amusement:-

[to the tune of something rousing and patriotic, to a marching band with snare drums and lot of brass]

Who is Mincing Your Meat?
Whose making it GOOD?
Are they the hands of an honest tommy
or the filthy paws of some foreign johnny.
Is your meat being manhandled by a card carrying commie oh
Who is Mincing Your Meat?

Anyway, I don't know who is mincing my meat. It come from Aldi so it's probably being minced by a huge machine where cows go in one end and then a 'mercy button' is depressed and mince comes out in shiny  packages at the other end. Who is pressing the button? Probably some nameless corporate drone working for minimum wage. Maybe I should email Foxholes farm and Shop and apologetically explain that I (like most people) am not on first name terms with the person who is operating the mincing machine.
Suggestions in the comments please.
