Why are burger eaters surprised?
As a vegan of 30 years, I am appalled that all the burgers 'tainted' by horse meat have been pulled off the shelves.
So all those animals were bred and slaughtered to end up in what? Landfill? And all due to burgers having a form of animal the consumer was not expecting.
What goes into the average hamburger, pie, or sausage, might horrify the average person if they actually knew what parts of animals end up in these cheap foods.
If consumers think this industry is completely 'clean', then they are deluding themselves.
