It’s good to have the occasional reminder that food safety is an issue everywhere.

See this item, by By Donald G. McNeil Jr. for NYT Health: Vitenam: With Rabies Deaths on the Rise, a Menu Item Gets a Closer Look.

Summarizing very briefly: Dogs can carry rabies. Few dogs in Vietnam are vaccinated against it. Lots of dogs are eaten in Vietnam, and it is apparently possible for the virus to spread from dogs to humans that way.

Education is clearly a factor here (eating a sick animal is not a good idea, and rabies produces visible signs). Technology is also a factor (Vietnamese have limited access to modern anti-rabies vaccine). As far as I can tell from this story, factory farming, however, is not part of the problem.
