Difficulty making both ends meat

There has been much in the media in recent weeks about the presence of horse meat in our burgers, mince and other processed foods. This does not concern me unduly. The French have always eaten horsemeat, and other than smelling of garlic is doesn't seem to have done them any harm.
On it's heels comes the news that ASDA SmartPrice corned beef might contain vets drugs.
This doesn't concern me either, as I rarely eat corned beef, and if I do it just means I'll get a decent nights sleep for a change. Probably.
It might concern me if my children were likely to eat drug contaminated meat, although this is as likely as an honest politician. The girl child appears top have turned into a vegetarian. I don't know why, but I suppose i have to live with it. The boy child is much more frustrating. He will eat processed chicken nuggets, made from reconstituted chicken and mechanically recovered crap pressed into loose chunks with bits of pork, fat and the lips and tongues etc, then covered in breadcrumbs so it looks nice. But he resolutely refuses to eat fresh chicken breast.
Even more frustrating is his stance over sausages. These are loosely speaking made of meat, the origin of which is debatable, breadcrumbs, spices and in some cases wood shavings. He will happily eat the middle of the sausages, but will not eat the ends. I have explained that the ends are exactly the same as the middle but to no avail. I have explained that the ends are entirely arbitrary, in that up until someone (or these days a machine) twists the sausages into separate links, that part of the sausage is exactly the same as the rest of the sausage. Does he understand this? Yes. Does he agree this is the case? No. Would it matter then if the people at Walls and Richmond filled the ends with wood pulp? After all, in the current recession they must be finding it as hard of the rest of us in making both ends meat.
