A recent case of mad cow disease on a Marabá property has led to the suspension of beef exports to China, in accordance with a 2015 bilateral agreement. The disease, identified in a nine-year-old cow that grazed on grass, is believed to be atypical, posing less risk than the classic type. This incident is expected to impact Brazil's beef market, with China accounting for approximately 60% of fresh beef exports. The article discusses the potential repercussions on meatpacking plants, particularly those with a strong focus on the Chinese market, and highlights the need for strategic planning among these entities. It also mentions the broader context of global beef market dynamics, including an anticipated record in Chinese beef imports and a predicted decline in U.S. production, and offers recommendations for different stakeholders to mitigate the effects on liquidity, pricing, and animal marketing.
