Brussels pulled Brazil's export papers this week, and the fallout stretches from São Paulo feedlots to a Luxembourg courtroom. As of September 3, Brazilian beef, poultry, fish, eggs, honey, horses and animal casings can no longer enter the 27-nation bloc, after regulators decided Brasília could not prove its farms keep antibiotics out of the food chain from birth to slaughter. Brazilian officials call the timing suspicious and the criteria unfair; European farm groups call it overdue. Both reactions are shaping a standoff that could last months for some products and years for others.
