The meat in Vietnam always seemed sketchy. Especially the sidewalk restaurants with the millions of flies flying around the warm glass cases with the meat. My meals improved quite a bit when I started ordering all my meals without meat.
I also didn't like how the Vietnamese cut a lot of their meat. It's like the only knives available are cleavers. Most of the meat that I ate had bones and skin and tendons. I wasn't used to that.
They are definitely trying to spread the word about food safety and hygiene. This is a billboard that I saw out there (north of Dong Hoi).
