Brazil's beef exports to China, worth approximately $4 billion annually, are under threat due to a suspension following the confirmation of two atypical mad cow disease cases. The suspension, now lasting over six weeks, has led to concerns and consternation among Brazilian authorities and meatpackers, including JBS and Marfrig. Despite assurances of transparency and no further detections of the disease, the ban's duration is uncertain, causing potential economic impact. This situation is mirrored by similar bans on Irish and British beef, highlighting China's increased focus on food security and import safety. The suspension is seen as a negotiation tactic by some, aiming to secure better pricing and trade terms. Meanwhile, Chinese importers are making necessary adjustments by sourcing beef from other countries like northern Europe and Kazakhstan, but experts expect the ban on Brazilian beef to be lifted this year.
