I love food and the public but my body can't handle it anymore
I think you're out of luck preparing or serving food. Obviously butchery is also very physically demanding. Depending on how much you can handle physically, you could consider sales, leading to a management position. 

Another career that would take networking skill to "get into" would be writing about food. 

As a blogger, you'd need strong writing skills and photography skills, but your career "ceiling" would be of your own making. I'm not aware of any well known blogs that center on butchery, that could be an option, but you'd really need to work hard at it to make a living at it. Take a look here for a bunch of books on the subject, and here for internet sources.

To work for somebody else as a food writer, they're mostly going to be looking for candidates with an apprenticeship background or formal education. Again, your butchery background could be a bit of an "in" if you're slick about it.

I can tell you from experience that you can learn A LOT about food writing by throwing yourself into this site. It will also help you to define exactly where your expertise lies. You'll find that the community gives excellent feedback, both positive and negative.
