We knew it was coming (and not just beef).
Remember last year when a lot of farms were culling herds due to the drought (and ethanol diversion to fuel laws) were driving up the price of feed grains. All the main stream media was talking about eventually when the surplus ran out prices would climb quickly due. Well that would be about now.
Also factor in the endless printing of money by the Fed with nothing to back it. This printing is the engine of the stock market boost and other things some people see as "recovery", when it's actually increased prices due to the constant and seemingly endless devaluation of the dollar one run of the printing press at a time.
There is a price to be paid for all of this (cutting of meat production, grain, printing, etc....) and it is starting to become apparent to more people.
