Probably related to the corn shortage we had this year. There was some serious drought in the heartlands that led to a lot of reduced corn crops. You'll probably see food prices go up a bit next spring...all food prices since corn is in damn near everything.
The bigger thing is that you'd better hold on to your beef. The drought seriously crippled a lot of cattle ranches as they couldn't afford enough feed for the cattle (grass was too dry, so they had to feed almost exclusively from purchased stock, which is VERY expensive). Pork will also likely increase, but I don't think it will be as significant as beef (pigs will eat just about anything people will, so you have more flexibility). Same with poultry as they can feed off of other things than corn.
Perhaps. Brazil and the EU are the second and third highest producers of beef, with the first being the US.
Shockingly, pork is nearly monopolized by China (at least as of 2010), so if anyone's going to try to edge the US out of the pork export game, they would be the ones.
