According to Trey Malone, assistant professor of agriculture, food and resource economics at Michigan State University’s College of Agriculture and Natural Resources, JBS is the second-largest producer of beef, pork and chicken in the U.S. If it were to shut down for even one day, the U.S. would lose almost a quarter of its beef-processing capacity, or the equivalent of 20,000 beef cows.

Malone also said the disruption could further raise meat prices ahead of summer barbecues. Even before the attack, U.S. meat prices were rising due to coronavirus shutdowns, bad weather and high plant absenteeism. The U.S. Department of Agriculture has said it expects beef prices to climb 1% to 2% this year, poultry as much as 1.5% and pork between by from 2% and 3%.
