It is amazing how this is a story that was caused by politician choices and the lack of supply and demand economics within a legislative body.
1.The shortage is projected for Europe, but the cause is blamed on American corn prices; this is not only due to the drought but also the allocation of corn to ethanol requirements. If one goes to the farming statistics kept by the U.S., (
http://www.ers.usda.gov/data-products/feed-grains-database/) the amount of corn produced has been increasing. But, because of political motivations, we need to burn portions of it, thus driving up the price.
2. The cost of raising pigs, legally, has gone up. In Florida there was an amendment to ban a method of raising pigs, those facilities had to adopt a new method, thus driving costs up.
