The upswing in the US has had a positive effect on Danish trade, helped by the weak Euro. Pork is one of Denmark's biggest exports. The Danske Slagterier association estimates that figures for 2000 will be over DKr24bn, a DKr3bn increase on the previous year.   "2000 was a good year,, said Karsten Flemin, a market analyst for Danske Slagterier, to Jyllands Posten, "and the outlook for 2001 is good, after the critical years of 1998 and 1999. Demand has increased and prices have risen. Unfortunately, much of pork's gain can be attributed to mad cow disease abroad and consumers' reduced interest in eating beef."
