If you're referring to the "pink slime" discussions, that has largely been discontinued, as has the use of ammonia washing. On top of that, it is hardly the same stuff, and I think that's really why McDonald's has been so overwhelmingly popular abroad. Being able to eat a McArabia in Dubai or having fried chicken wings in China I imagine is the result of rigorous market research on what's popular in those environments. They use their quality as the main selling point to get people in the door, and that's definitely contributed to their image.
