Federal immigration raids in beef-producing regions of Republican states have prompted a forceful reaction from industry associations in Texas, Oklahoma and Kansas, and unusual pushback from Republican officials just weeks out from the midterm elections. The associations warned the Trump administration’s immigration enforcement actions “will lead to higher beef prices” at a time when prices of groceries and fuel are already top concerns for voters.

The most recent Immigration and Customs Enforcement raids occurred in Kansas, near the border with Texas and Oklahoma, and appeared to come without warning or, according to both Kansas senators, cooperation with local authorities. “When ICE operates in Kansas, it needs to coordinate with our local law enforcement,” Senator Roger Marshall of Kansas, a strong ally of President Trump who is locked in an unexpectedly tough re-election fight, said in a statement on Wednesday.

The enforcement activity began Wednesday morning in an area of southwest Kansas that is sometimes called the golden triangle of beef. Local officials said they were not given advance notice and received no information about the number of arrests. People were pulled over on the main road to one of the meatpacking plants, causing shifts to be adjusted because of employees who were either already detained or afraid to drive to work.

The U.S. cattle herd is at its smallest level since the 1950s. Drought has persisted across cattle country. Tariffs and the war in Iran have raised the price of feed, fertilizer and diesel fuel. In June, Texas confirmed the arrival of the New World screwworm. “We need some help, and these ICE raids do not help,” said Sid Miller, the Texas agriculture commissioner and a Republican.
