In a statement, Cal-Maine president and CEO Sherman Miller attributed the company's soaring profits to "the ongoing epidemic of highly pathogenic avian influenza which has significantly reduced the nation's egg-laying capacity."
According to the United States Department of Agriculture, "U.S. egg inventories were 29% lower in the final week of December 2022 than at the beginning of the year," while "more than 43 million egg-laying hens were lost to the disease itself or to depopulation since the outbreak began in February 2022."
Sanders (I-Vt.)—who took on agricultural monopolies while campaigning for president in 2016 and 2020—questioned Cal-Maine's narrative in a tweet arguing that "we must break up Big Ag and enact a windfall profits tax."
Sanders wasn't the only congressional critic of Cal-Maine's latest profits.
"While working families paid record prices for eggs, Cal-Maine raked over 700% more in profits—without reporting a single case of avian flu," Sen. Elizabeth Warren (D-Mass.) tweeted on Thursday. "We need to crack down on corporate price gouging to provide Americans with relief at the grocery store."
Rep. Katie Porter (D-Calif.), who is running for U.S. Senate, wrote on Twitter last week that "corporate greed is driving inflation."
"We need more competition to drive down prices," she added. "In the meantime, I'm demanding answers from Cal-Maine directly."
In February, Warren and Porter wrote letters to the heads of the five biggest U.S. egg producers expressing their concern over the "massive spike" in prices and "the extent to which egg producers may be using fears about avian flu and supply shocks as a cover to pad their own profits at the expense of American families."
The advocacy group Farm Action earlier this year implored the Federal Trade Commission to investigate "apparent price gouging, price coordination, and other unfair or deceptive acts or practices by dominant producers of eggs such as Cal-Maine Foods."
