SAO PAULO (AP) — President Donald Trump’s threat to boost import taxes by 50% on Brazilian goods could drive up the cost of breakfast in the United States. The prices of coffee and orange juice — two staples of the American morning diet — could be severely impacted if there’s no agreement by Aug. 1.

Brazilian President Lula da Silva vowed to trigger Brazil's reciprocity law if negotiations with the U.S. fail.

The proposal is a blow to U.S. meat companies also facing tighter cattle supplies due to a halt of livestock imports from Mexico over New World screwworm, a flesh-eating pest spreading south of the border.
