More than 90 percent of U.S. store-brand chickens have the muscle disease known as “white striping,” according to findings released on Monday by The Humane League.

White striping disease is a muscle myopathy that occurs when chickens are bred for rapid growth. The stripes appear on the chickens when they are unable to keep up with the unnaturally fast muscle growth, which can also create problems with blood and oxygen flow.

As a result, the chickens replace muscle tissue with fibrous tissue and fat, which subsequently reduces the nutritional value of the meat by increasing the fat content by 224 percent and giving lower protein levels by 9 percent. White striping reportedly impacts 50–96 percent of fast-growing chickens.

Between May 2021 through July 2021, The Humane League, a global animal protection nonprofit, conducted an investigation on white striping disease in chickens on supermarket shelves to see if they had similar levels to those reported in scientific journals.

The investigation (pdf) analyzed meat cases at major supermarkets across 29 states, including Walmart, Kroger, Costco, Albertsons, Ahold Delhaize, Publix, Target, H-E-B, Meijer, Aldi, Wakefern, Trader Joe’s, HyVee, BJ’s Wholesale Club, Wegmans, and Giant Eagle.

Researchers found that white striping disease was evident in 99 percent of chicken inventory, while some supermarkets had white striping in 100 percent of the packets it sampled.

All 16 of the supermarkets analysed had white striping present in their their standard own-brand chicken breast fillets, while 70 percent of chicken packages had moderate to severe white striping.

The “worst offenders” were Walmart, BJ’s, and Meijer, with moderate to severe white striping present in 93 percent, 87 percent, and 85 percent of their chickens respectively.

“The fact that 99 percent of all store-brand chicken sold in major supermarkets contains the white striping disease should raise alarm bells for consumers everywhere,” said David Coman-Hidy, president of The Humane League, in a release.

“This disease is a visual reminder of the terrible suffering of these weeks-old animals and the control that these factory farms have over our food supply. It’s nearly impossible for Americans to find an alternative to this diseased meat.”

According to The Humane League’s report, white striping affected less than 5 percent of chickens some 10 years ago but that figure drastically rose within five years to 96 percent.

The group also cites data from the Sentience Institute that estimates 99 percent of all U.S. farmed animals are currently living in factory farms.

The Humane League says that while a 2018 study found that 50 percent of shoppers said they would not buy chicken with white striping, consumers are no longer being presented with any option but to buy factory-farmed chicken from supermarket brands.

“Food companies must make the shift to slower-growth chicken breeds—by adopting the Better Chicken Commitment—to improve consumer choice, human health, and animal welfare,” the group wrote.

The findings were discounted by the National Chicken Council, with a spokesperson telling CBS MoneyWatch that “white striping is not a disease,” and is instead a “quality factor in chicken breast meat caused by deposits of fat in the muscle during the bird’s growth and development.”

The spokesperson noted that only 3 to 6 percent of birds in commercial flocks have severe cases of white striping, while the majority of meat with severe cases of the disease is used in processed products and not sold as boneless, skinless breasts.

“So, when consumers purchase meat at the store, the meat does not have white striping,” he added.
