The article highlights the significant impact of China's suspension of Brazilian beef imports, following two atypical mad cow disease cases, on Brazil's agricultural sector, particularly reducing the price of fat ox to a two-month low. The suspension has led to a decrease in beef exports, affecting both domestic and international markets. The situation is further complicated by China's economic challenges, including slow GDP growth, energy crisis, and issues with conglomerate Evergrande. The suspension has forced Brazilian producers to face challenges, with reduced demand and increased costs. The article also mentions the potential return of other countries to the market, such as Iran, and anticipates a further decrease in beef prices due to increased costs for slaughterhouses. Additionally, the prices of other proteins, like frozen chicken and pork, have seen a decline due to the overall market downturn.
