Washington, DC – Agriculture Secretary Ann Veneman says her department's mad cow probe has "made a lot of headway in the last five weeks." Veneman testified before a Senate Committee Tuesday. She said that protection systems have been enhanced, consumer confidence in the beef supply remains high and that work is being done to reopen foreign markets to US beef. Meanwhile, South Korea still isn't convinced. They've rejected the latest US safeguards against BSE, saying they will not lift a ban on American beef until the meat is "scientifically proven" safe. Some 30 countires have such bans. 10% of the Wyoming Livestock industry's business comes from International trade.
