Glass Onion's posted reply said "They may have a beef with high fructose corn syrup."
"Have a beef" = To have an argument or concern with something.
I don't think the OP said there were hidden sugars in meat though? If it's one of those packaged pre-cooked or ready-to-cook meats and has flavoring .... say, like "Honey Teriyaki Beef" or something ... then yeah, that would have sugar in it. But by law it would have to be listed in the ingredients.
