Where was it imported from? Um!............... three guesses.
Urban legend and monkey sandwich story.
The USA is a major exporter of chicken meat and does not import any chicken meat whatsoever.
The contrary is true: China imports enormous quantities of chicken feet and pork trotters from the US and Europe.
Pound for pound, is rat meat worse for your health than chicken?
Probably better. Less added hormones in it.
This is defitely a hoax of some kind. America actually began importing some chicken and some meat products from China a few years back but it has been fright with issues with meat containing banned chemicals. China still uses DDT to spray crops and also uses phosphorous to keep the DDT on the crops. It is true fox, dog and rat meat are used for making faux beef products but I doubt they would try to export that stuff.
