According to records from the USDA Economic Research Service, the U.S. imported 140.9 million pounds of beef from Brazil last year. Mar 29, 2019
In 2018, Brazil was the world's largest exporter of beef (6,393,406,700 pounds), providing close to 20 percent of total global beef exports, outpacing India, the second-largest exporter, by 527,000 metric tons (1,161,836,321 pounds) carcass weight equivalent (CWE). Jul 1, 2019.
The US does not even rank in the top 15 countries that import from Brazil.
Brazil has the world's second-largest cattle herd—232 million head—and its production is largely based on grass.
USDA's Foreign Agriculture Service (FAS), programs that subsidize and improve pastures and crossbreeding are primary drivers of the overall increase of cattle production in 2019 (another significant factor is improved pasture conditions in major production regions).
Between 1990 and 2018, the Brazilian cattle herd expanded by 56 percent. Brazil's beef production last peaked in 2014, when it reached 9.7 million metric tons CWE. During Brazil's 2014-16 recession, coupled with devaluation of Brazil's national currency, the Brazilian real, beef output continued to grow, though at a slower pace, while higher local-currency denominated prices compensated for higher production expenses.
