Robot Butchers? Technology coming to your table


Recently, an article came across my desk from one of my meat industry news updates about JBS meat packing looking into using robots to process swine and lamb carcasses initially, with beef to eventually follow. In college I spent a lot of time in packing plants collecting beef carcass data, meat, and other tissues needed for samples. While I think it can be done, I think there may be some challenges (i.e. animal welfare, food safety, lack of human element) that will have to be overcome before we are ready to turn over meat processing to robots.

Below is a summation of articles from Harvest Media News and NPR on meat cutting robots. What are your thoughts about this high tech and revolutionary idea?

Slaughterhouses and meatpacking plants throughout the country employ about a quarter of a million persons.  Some of those workers that prepare the beef, pork, and chicken that ends up on dinner tables could eventually be replaced by robots. The world’s largest meatpacking company (JBS, the Brazil-based protein powerhouse) is looking at ways to automate the art of butchery.

Late last fall, JBS bought a controlling share of Scott Technology, a New Zealand-based robotics firm. While many manufacturers have gone to automated machines to process and package everything from food to furniture, the beef industry has held onto its workers. It takes thousands of workers to run a modern beef plant. In fact, U.S. meatpacking plants are expected to add jobs in the next decade, as the appetite for pork, chicken, and beef grows in the developing world.

Disassembly is the name of the game on the fabrication floor at the JBS beef processing plant in Greeley, Colorado. Workers hold a knife in one hand, and their sharpening steel is close to their side. Line workers are dressed in chainmail, a protective mesh lining under white jackets (frocks/smocks) and aprons. Deft cuts cleave bone and meat, turning a whole cow into neat and trim cuts like tenderloins, steaks, and roasts.

“There’s right now 850 people out in this building alone,” says plant manager Bill Danley as he weaves through the maze of conveyor belts, stainless steel slides, and bone bins. The plant is a far cry from your grandfather’s butcher shop, where a single person would need to know how to turn an entire animal into cuts of meat. Large beef companies like JBS, Cargill, and Tyson have turned each minute step of the process into a job. Danley lists some of the titles: chuck boner, tender puller, back splitter, knuckle dropper, and tail ripper. “There’s a lot of jobs out here that prep for the other person,” Danley says.

Each year JBS pays out more than $100 million in paychecks to its 3,000 employees. It’s a huge chunk of the company’s operating costs. That could begin to change with JBS’ new venture into the world of robotics. “This is a very innovative and exciting company that we invested in,” JBS spokesman Cameron Bruett says of the company’s investment in Scott Technology. “And we’re excited to see what they’ll come up with.”

JBS is looking at how robots could fit into its lamb and pork plants first, Bruett says. Sheep and pigs tend to be more uniform than beef cattle. “Now when it comes to beef packing, beef processing, the fabrication of the animal, it’s very difficult to automate beef processing,” Bruett says. The various breeds of cattle brought into the plant also complicate the future of robots in meatpacking. Some days the plant breaks down the long, lanky bodies of Holsteins. Other days they’re working on sturdy, thickset Angus and Hereford. Robots would need the ability to adjust to the spectrum of cattle breeds.

The meatpacking robots of today use vision technology to slice and dice, but the key to butchery is touch, not sight. JBS’s beef division president, Bill Rupp, says right now, robots just can’t feel how deep a bone is, or expertly remove a filet mignon. “When you get into that detailed, skilled cutting, robots aren’t there yet. Someday, I’m sure they will be,” Rupp says. “It can’t do the fine cutting that you see on the fab floor, that’s one of the big challenges right now.” Robotic technology doesn’t have the fine motor skills that come easily to humans and there isn’t room for error. Some of the cuts being boxed up bring upward of $14 per pound, Rupp explains, so the key is being able to leave it on the meat and not on the bone. “I mean that’s how our business works.”

The technology isn’t quite ready for a massive roll out, but could the economics of widespread robotic use in the beef industry ever work? Not any time soon, says Don Stull, an anthropologist who spent 30 years studying the cultures of meatpacking towns at the University of Kansas. “Workers are really cheaper than machines,” Stull says. “Machines have to be maintained. They have to be taken good care of. And that’s not really true of workers. As long as there is a steady supply, workers are relatively inexpensive.” There’s a stream of immigrants and refugees, most from Somalia, Rwanda, El Salvador, and Guatemala, ready to put on the chainmail and pick up the knife, Stull says. In large, modern plants, companies pay less because the skill needed to work on the fabrication floor is so low. Some jobs take less than a week to fully master. Turnover in the industry is high, Stull points out, because of the physical demands. Slicing meat all day can lead to repetitive injuries. JBS employs an athletic trainer to keep employees limber and fit. Stull says it’s still common for workers to transfer jobs at the same plant to make better money or to just avoid falling apart. “After you do the same thing thousands of times a day, six days a week … your body wears down,” Stull says.

While the industry says it has dramatically improved on worker safety over the years, meatpacking jobs consistently rank among the most hazardous in the country. Workers stand along conveyor belts on raised platforms, adjustable based on each person’s height. Those platforms were a big step in improving ergonomic conditions for workers, Danley says. Increased automation could ease some of those injuries.

Meat processing makes up a huge portion of Great Plains communities’ rural economies, what happens inside meat processing plants affects not only the companies involved, but the very culture of rural America.

Until technology catches up in both skill and costs, meatpacking companies will continue hiring workers to turn cattle, chickens, and hogs into cuts of meat.

  1. Lindsay,

    I worked at the Cargill plant at Schuyler for 13 months after I graduated college. The engineering and how a big plant works still amazes me.

    When I left Cargill, Schuyler was just installing “smart tables” on the fab floor. I’ve always wondered how that adjustment worked. They were also working on upgrading the REA camera in the coolers. It would be fun to tour the plant and see the advancements they have made in the last 12 years.
