WASHINGTON, Sept 8 (Reuters) - The Biden administration plans to take a tougher stance toward meatpacking companies it says are causing sticker shock at grocery stores. Four companies control much of the U.S. meat processing market, and top aides to President Joe Biden blamed those companies for rising food prices in a blog on Wednesday. As part of a set of initiatives, the administration will funnel $1.4 billion in COVID-19 pandemic stimulus money to small meat producers and workers, administration aides said in the blog post. They also promised action to "crack down on illegal price fixing." Four companies slaughtered about 85% of U.S. grain-fattened cattle that are made into steaks, beef roasts and other cuts of meat for consumers in 2018, according to the most recent data from the U.S. Department of Agriculture (USDA). The big four processors in the U.S. beef sector are: Cargill (CARG.UL), a global commodity trader based in Minnesota; Tyson Foods Inc (TSN.N), the chicken producer that is the biggest U.S. meat company by sales; Brazil-based JBS SA (JBSS3.SA), the world"s biggest meatpacker; and National Beef Packing Co (NBEEF.UL), which is controlled by Brazilian beef producer Marfrig Global Foods SA (MRFG3.SA). Tyson Foods, which sells beef, pork and chicken, rejected the White House"s assertion that consolidation in the meatpacking sector is driving up prices. The company blamed the pandemic and the U.S. labor shortage for limiting production. Its shares ended 1.4% lower at $76.17. "Tyson"s scale allows it to operate efficiently, which keeps costs down for consumers," the company said. Cargill, JBS and National Beef made no comment.

"Issuing inflammatory statements that ignore the fundamentals of how supply and demand affects markets accomplishes nothing," said Mark Dopp, chief operating officer for the North American Meat Institute, an industry group that represents meatpackers.

The administration sees those companies collecting too much profit after the stimulus helped prop up demand for their products. "We"ve helped sustain this market, and it"s frustrating to see these companies turn around and raise prices," Bharat Ramamurti, deputy director of the White House"s National Economic Council, said in an interview.

Rising inflation has posed a serious threat to Biden"s efforts to get a grip on the COVID-19 pandemic - his top priority as president - and engineer an economic recovery from the recession it caused. The Biden administration has responded partly by ramping up efforts to crack down on what it sees as anticompetitive and monopolistic behavior that could be increasing prices. A meeting of a new White House Competition Council created by Biden is set for Friday. The USDA and the Department of Justice have already been conducting an investigation into price-fixing in the chicken-processing industry. read more "The goal of that over time is to bring these prices down," said Ramamurti. U.S. lawmakers are seeking increased oversight of the beef sector as concerns about anticompetitive behavior increase after the pandemic and a cyberattack on JBS USA. read more The administration is "encouraged" by bipartisan legislation that could aid more price negotiation in the meat market, it said in the blog.
