One of the most affected agricultural sectors is the meat industry. Mexico has gone from a small-key player in the pre-1994 U.S. export market to the 2nd largest importer of U.S. agricultural products in 2004, and NAFTA may be credited as a major catalyst for this change. The allowance of free trade removed the hurdles that impeded business between the two countries. As a result, Mexico has provided a growing market for meat for the U.S., leading to an increase in sales and profits for the U.S. meat industry. This coincides with a noticeable increase in Mexican per capita GDP that has created large changes in meat consumption patterns, implying that Mexicans can now afford to buy more meat and thus per capita meat consumption has grown.
