Former President Donald Trump helped meatpacking companies speed up the production lines inside their plants to process more animals, despite worries it could lead to more injuries for workers. But so far, the Biden administration has delivered a very different message: Not so fast.

The pork industry suffered a setback this week when President Joe Bidens Agriculture Department said it would comply with a court ruling invalidating key parts of a Trump-era meatpacking rule. As a result, some pork facilities will have to back down the speed of their lines.

The Trump rule had allowed certain plants to jack up their speeds above the traditional cap of 1,106 hogs per hour. But a federal judge in Minnesota ruled in March that USDA officials under Trump instituted that rule in an arbitrary and capricious manner, failing to take worker safety into account. The judge gave hog processors and the USDA 90 days to sort things out.

The pork industry lobby asked the Biden administration to appeal the ruling, arguing it would hurt meat production to slow the plants. But it now appears unlikely the administration will do that.

The USDA posted an alert Wednesday telling pork plants to be ready to slow their lines down by June 30. The agency said that it was committed to worker safety and ensuring a safe, reliable food supply, and that it planned to comply with the Minnesota ruling.

The move was cheered by the United Food and Commercial Workers, a union representing 33,000 workers in pork plants. The UFCW and the progressive advocacy group Public Citizen filed the Minnesota lawsuit, arguing the Trump rule was dangerous.

The safety of Americas frontline food workers must never again take a backseat to corporate profits, the unions president, Marc Perrone, said in a statement.

Worker groups and the meat industry have fought for years over line speeds. Meat producers claim they can increase production safely, but unions and occupational health experts say the faster speeds lead to more hazards in a field known for repetitive-motion injuries and other damage.
