A case of 'mad cow disease' has been identified in a bovine in Marába, Pará, leading to an embargo on Brazilian meat exports to China. The governor of Pará, Helder Barbalho, expects the results from a Canadian laboratory to confirm the case as unusual and for exports to China to be reinstated by the end of March. Despite the local market impact, Barbalho believes the price of meat will decrease due to the Chinese market's increased offer. He praises the Ministry of Agriculture and Livestock's handling of the situation, stating it demonstrates Brazil's commitment to its rules.
