In 1993, the North American Free Trade Agreement (NAFTA) was passed.
            
 Included was a gradual removal of tariffs on various goods traded between
            
 Mexico, Canada and the United States.  The  first implementation of these
            
 tariff removals began on January 1, 1994. According to the U.S. information
            
 service, "Under the NAFTA, all non tariff barriers to agricultural trade
            
 between the United States and Mexico were eliminated. In addition, many
            
 tariffs were eliminated immediately, with others to be phased out,
            
 resulting in full implementation of all agricultural provisions by the year
            
 2008."  (Economic Perspectives, June 1996)
            
       It may be worth noting, in the aftermath of the recent outbreak of
            
 mad cow disease in a northwestern United States dairy herd that among the
            
 tariffs removed, making trade easier and more profitable for Canada, were
            
 restrictions and tariffs on agricultural products, including cattle.  The
            
 infected cow was traced to a dairy cow producer in Canada.  Since 1989, a
            
 U.S.-Canada Free Trade Agreement had been in effect; all the provisions
            
 incorporated in that, including tariffs, had been incorporated into NAFTA
            
 all tariff affecting agricultural trade between those two signatories to
            
 NAFTA had been removed by January 1, 1998.  (Economic Perspectives, June
            
       A similar process was instituted, under NAFTA, regarding Mexico.  All
            
 non tariff measures affecting agricultural trade between the U.S. and Mexico
            
 were eliminated in that  first round, on January 1, 1994.  Tariffs were to
            
 be eliminated in phases, with some tariff removed almost immediately.    On
            
 January 1, 1996, the third round of tariff cuts with Mexico went into
            
 effect. Duty-free U.S. access increased 3 percent under Mexico's tariff-
            
 rate quotas covering corn, dried beans, poultry, barley, animal fats, eggs,
            
 and potatoes.  (Economic Perspectives, June 1996)
