I try to not eat anything from Mexico.. If veg is from there I pass on it.. Only eat if nothing else is avail.. Besides that their Vegetables are just as high as USA grown.. Somtimes higher..
I also try not to eat anything from Mexico, considering the filthy personal hygiene of the agricultural workers. And the fact that they use human waste for fertilizer. However, virtually all blackberries I'm seeing in markets now come from Mexico. Don't know why. Commercially made guacamole also seems to be made exclusively in Mexico. Why can't we make it here?
A lot of the produce that we get from Mexico is grown by Mennonite and Mormon colonies that moved down there for the cheaper land.
