Chicken companies spent decades breeding birds to grow rapidly and develop large breast muscles. Now the industry is spending hundreds of millions of dollars to deal with the consequences ranging from squishy fillets known as “spaghetti meat,” because they pull apart easily, to leathery ones known as “woody breast.”
The abnormalities pose no food safety risk, researchers and industry officials say. They are suspected side effects of genetic selection that now allows meat companies to raise a 6.3-pound bird in 47 days, roughly twice as fast as 50 years ago, according to the National Chicken Council.
That efficiency drive has helped U.S. meat giants such as Tyson Foods Inc., TSN +1.31%Pilgrim’s Pride Corp. PPC +1.26% , Perdue Farms Inc. and Sanderson Farms Inc.SAFM +0.69% produce a record 42 billion pounds of chicken nuggets, tenders and other products in 2018. Now, it’s adding an estimated $200 million or more in annual industry expenses to identify and divert breast fillets that are too tough, too squishy or too striped with bands of white tissue to sell in restaurants or grocery stores, according to researchers at the University of Arkansas.
.. Spaghetti meat—a name researchers have given chicken breast fillets that can be picked up and pulled apart by hand, or punctured easily with a fingertip—began appearing in 2015 and now can be detected in around 4% to 5% of breast meat samples, researchers said.
“It looks like spaghetti noodles,” said Dr. Casey Owens, a University of Arkansas professor, adding that the affected muscle fibers have a stringy texture.Some restaurant and grocery companies aren’t waiting for chicken companies to solve the problems. Burger chain Wendy’s Co. WEN -1.91% in 2016 noticed toughness in some of its grilled chicken sandwiches. The chain in 2017 began shifting its chicken supply to smaller birds, slaughtered before they reach 7.5 pounds, though the size of its chicken fillets have stayed the same.
The transition meant $30 million in higher costs for Wendy’s, because the smaller chickens have made meat suppliers’ operations less efficient. “But we noticed immediately, consumer feedback on our chicken products was consistently good, and better than it was prior to this change,” a spokeswoman said.
Grocery chain Whole Foods Market in 2016 said it would shift its chicken purchasing toward slower-growing varieties, citing animal welfare and quality benefits.
Panera Bread plans to start testing slower-growing birds following a Canadian study on different breeds, said Sara Burnett, the chain’s head of food and wellness.
Some chicken companies, including Mississippi-based Sanderson Farms, have begun slaughtering chickens at slightly younger ages to reduce the frequency of meat affected by woody breast. That cut in half the company’s number of “woody” chicken breasts, bringing the overall frequency to low single digits, said Chief Financial Officer Mike Cockrell.
Chicken industry officials are confident that their high-tech breeding operations eventually will be able to minimize the problems through genetic selection, the way the industry has resolved previous side effects of fast growth in birds, like weak leg bones and heart problems. The process, officials said, is likely to take another few years.
The U.S. Poultry and Egg Association over the past three years has invested half a million dollars in research projects to help pinpoint the cause of the problems and identify nutrients that could mitigate them.
One effort involves adapting bioelectrical technology used in the seafood industry, which could help detect abnormalities, said Dr. John Glisson, vice president of research for the Georgia-based trade group.
Encountering such chicken breasts as a consumer isn’t pleasant, said Dr. Glisson. He said he unknowingly bit into a woody breast-afflicted chicken sandwich a couple of years ago at a fast-food restaurant. “It’s like a piece of leather,” he said.
Some 60 billion chickens are killed for human consumption each year; in the future
.. The Anthropocene is a product of our fantasies of a frictionless, hyper-connected world. Humans created 5 billion gigabytes of digital information in 2003; in 2013 it took only 10 minutes to produce the same amount of data.
It was like Mr. Trump giving his second wife, Marla Maples, a prenuptial agreement that would eventually have provided her with a serious piece of his fortune — then dumping her just months before her entitlement was to come due.
.. he was born rich but still managed to mock other scions of inherited wealth as members of the “lucky sperm” club, and also the part about how his father incessantly urged him on, chanting, “you are a killer … you are a king.”
.. The thing in my book that caught Mr. Trump’s eye was a line about the advantages of looking like a lunatic. It’s right up front in his introduction: “Almost all successful alpha personalities display a single-minded determination to impose their vision on the world, an irrational belief in unreasonable goals, bordering at times on lunacy.” He also liked the idea that it was possible to win the game of chicken by convincing opponents that “he might actually enjoy a head-on collision.”
