Two out of three major meat packers in Brazil, Minerva and Marfrig, are redirecting Chinese beef orders to Argentina and Uruguay following a voluntary suspension of Brazilian beef exports by the Ministry of Agriculture due to a potential case of 'mad cow' disease. The decision to suspend exports is part of a bilateral agreement with China, and Beijing has not set a deadline for the resumption of exports. The suspension has caused economic disruption in the production chain. Atypical cases of the disease, which do not pose a risk to humans or other cattle, are spontaneously occurring in old animals. The Association of Breeders of Mato Grosso is calling for a review of the bilateral agreement, arguing that it leads to unnecessary export suspensions.
