Exports of Brazilian cattle to China have been suspended due to a case of mad cow disease, leading to a decrease in cattle prices in Brazil and Paraguay. The Mercosur Steer Faxmeat Index fell by 8 cents to US$ 3.61 per kilo carcass, and the average price in Brazil's main exporting states dropped to US$3.20 per kilo carcass. In Paraguay, the price for male slaughter cattle fell by 35-40 cents to US$3.20 per kilo carcass. Meanwhile, prices in Argentina stabilized after a significant increase, and in Uruguay, prices for special export steers are recovering.
