CATO, N.Y. — Federal agents forced open the doors of a snack bar manufacturer and took away dozens of workers in a surprise enforcement action that the plant’s co-owner called “terrifying.”

Video and photos taken at the Nutrition Bar Confectioners plant Thursday showed numerous law enforcement vehicles outside the plant and workers being escorted from the building to a Border Patrol van. Immigration agents ordered everyone to a lunchroom, where they asked for proof the workers were in the country legally, according to one 24-year-old worker who was briefly detained.

The reason for the enforcement action was unclear. Local law enforcement officials said the operation was led by U.S. Homeland Security Investigations, which did not respond to requests for information. Nutrition Bar Confectioners co-owner Lenny Schmidt said he was also in the dark about the purpose of the raid.

“There’s got to be a better way to do it,” Schmidt told the Associated Press on Friday at the family-owned business in Cato, N.Y., about 30 miles west of Syracuse.

The facility’s employees had all been vetted and had legal documentation, Schmidt said, adding that he would have cooperated with law enforcement if he’d been told there were concerns.

“Coming in like they did, it’s frightening for everybody — the Latinos … that work here, and everybody else that works here as well, even myself and my family. It’s terrifying,” he said.

Cayuga County Sheriff Brian Schenck said his deputies were among those on scene Thursday morning after being asked a month ago to assist federal agencies in executing a search warrant “relative to an ongoing criminal investigation.”

He did not detail the nature of the investigation.

The lack of explanation raised questions for state Sen. Rachel May, a Democrat who represents the district.

“It’s not clear to me, if it’s a long-standing criminal investigation, why the workers would have been rounded up,” May said by phone Friday. “I feel like there are things that don’t quite add up.”

Worker describes raid

The 24-year-old worker, who spoke to the AP on condition of anonymity because he feared retribution, said that after he showed the agents he is a legal U.S. resident, they wrote down his information and photographed him.

“Some of the women started to cry because their kids were at school or at day care. It was very sad to see,” said the worker, who arrived from Guatemala six years ago and became a legal resident two years ago.

He said his partner lacked legal status and was among those taken away.

The two of them started working at the factory about two years ago. He was assigned to the snack bar wrapping department and she to the packing area. He said he couldn’t talk to her before she was led away by agents and didn’t know Friday where she had been detained.

“What they are doing to us is not right. We’re here to work. We are not criminals,” he said.

Schmidt said he believed immigration enforcement agents are singling out any company with “some sort of Hispanic workforce, whether small or large.”

The raid came the same day that immigration authorities detained 475 people, most of them South Korean nationals, at a manufacturing site in Georgia where Korean automaker Hyundai makes electric vehicles.

Without his missing employees, Schmidt estimated production at the food manufacturer would drop by about half, making it a challenge to meet customer demand. The plant employs close to 230 people.

“We’ll just do what we need to do to move forward to give our customers the product that they need,” he said, “and then slowly recoup, rehire where we need.”

Dozens held

New York Gov. Kathy Hochul, a Democrat, said the workers detained included parents of “at least a dozen children at risk of returning from school to an empty house.”

“I’ve made it clear: New York will work with the federal government to secure our borders and deport violent criminals, but we will never stand for masked ICE agents separating families and abandoning children,” she said in a statement.

The advocacy group Rural and Migrant Ministry said 50 to 60 people, most of them from Guatemala, were still being held Friday. Among those released late Thursday, after about 11 hours, was a mother of a newborn who needed to nurse her baby, said the group’s chief program officer, Wilmer Jimenez.

The worker who was briefly detained said he has been helping to support his parents and siblings, who grow corn and beans in Guatemala.

He said he took Friday off but plans to get back to work Monday.

“I have to go back because I can’t be without work,” he said.
