Most people assume the biggest risk with a Costco rotisserie chicken is eating the whole thing in one sitting. Fair enough — they’re delicious and absurdly cheap. But it turns out the real concerns have nothing to do with willpower. Between a class-action lawsuit over misleading labels and some genuinely alarming food safety data from the plant that produces millions of these birds, that $4.99 price tag may be hiding costs nobody’s talking about.
Costco built a $450 million empire around a cheap chicken
Here’s some context most shoppers don’t have. In 2019, Costco opened a massive poultry complex in Fremont, Nebraska called Lincoln Premium Poultry (LPP). The price tag? Around $450 million. The goal was simple: keep that rotisserie chicken locked at $4.99 forever by controlling every single stage of production. Hatcheries, feed mills, grower farms, slaughter, processing, distribution — all of it under one corporate roof. This is called vertical integration, and on paper, it sounds like a smart play.
The numbers are staggering. Costco reported selling about 157.4 million rotisserie chickens globally last year. The LPP plant alone processes more than 100 million chickens annually, supplying both the famous rotisserie birds and Kirkland Signature raw chicken breasts. That’s a lot of poultry flowing through a single facility. And controlling the supply chain was supposed to guarantee both quality and safety.
Supposed to. That word is doing heavy lifting here.
The salmonella numbers are bad
The USDA uses a three-category rating system for salmonella contamination at poultry plants. Category 1 is the best. Category 3 means the facility failed the standard. According to an analysis of USDA data, Costco’s Lincoln Premium Poultry plant has received a Category 3 rating 92% of the time since it opened in 2019. That’s not an occasional bad month. That’s essentially a permanent failing grade.
More recent numbers don’t paint a better picture. The Fremont plant reportedly received Category 3 ratings in every single monthly test from September 2023 through July 2025. It also landed on Consumer Reports’ 2025 list of the nation’s most contaminated poultry plants. So when you do the math on what this means for actual shoppers: roughly 1 in 10 whole chickens from the plant may have entered stores contaminated with salmonella. For raw chicken breast packages, that number jumps to about 1 in 6.
If you’re picking up a couple packages of chicken breasts on your weekly Costco run, the odds are decent you’re bringing home salmonella-contaminated poultry at least once a month. Which, honestly, is kind of wild to think about while you’re standing in that checkout line.
Why the USDA can’t actually do anything about it
You’d think that repeatedly failing federal safety standards would trigger some kind of enforcement. A shutdown. A recall. Something. But here’s where the system falls apart: the USDA can inspect and assign ratings, and those ratings are posted publicly on the agency’s website. That’s about where the agency’s power ends. It cannot mandate recalls. It cannot halt sales. It cannot shut down plants that fail over and over again. Contaminated raw chicken can legally stay on store shelves unless the seller — Costco, in this case — voluntarily pulls the product.
There was a brief window of hope. In 2024, the USDA’s Food Safety and Inspection Service proposed a framework that would have classified salmonella as an adulterant in raw poultry, making it illegal to sell contaminated products. That proposed rule was withdrawn in April 2025. So we’re right back where we started — a regulator that can identify the problem but can’t actually fix it.
The conditions that make contamination almost inevitable
The poultry industry has long maintained that salmonella contamination is just an unavoidable reality. That’s a convenient position when the way birds are bred, raised, and processed practically guarantees the problem. Contamination doesn’t start at the slaughterhouse. It starts much earlier — at the genetic level. Costco’s birds, like most commercially raised chickens, are bred to grow so abnormally fast that many can barely stand. Their bodies outpace their immune systems, leaving them more vulnerable to illness, including salmonella.
The pathogen gets passed through eggs at hatcheries, then travels through the rest of the supply chain. Chickens are raised in barns holding tens of thousands of birds in dimly lit, ammonia-heavy spaces thick with feces and dead birds. A 2021 investigation by Mercy for Animals documented exactly these conditions at facilities connected to Costco’s supply chain — birds too large to walk, open sores, animals that couldn’t reach food or water. Costco’s response at the time? They called much of the footage “normal and uneventful activity.” Read that again. Normal.
Transport adds another layer. USDA inspection reports document thousands of Costco birds dying during transit in recent years — freezing to death, suffocating in overcrowded trucks, or dying in a trailer fire. Every year, 7.2 million birds die before they even make it to slaughter. And stressed, sick animals carry more pathogens. The USDA itself acknowledges that poor welfare conditions increase pathogen levels. It’s a loop that feeds on itself — quite literally.
Now there’s a lawsuit about the label, too
On a completely different front, Costco is also dealing with a class-action lawsuit that has nothing to do with salmonella and everything to do with two words on the packaging: “no preservatives.” Filed in federal court in San Diego, the complaint alleges that Costco has been misleading customers about what’s actually in its Kirkland Signature Seasoned Rotisserie Chicken.
The ingredients at the center of the dispute are sodium phosphate and carrageenan. Both are FDA-approved and classified as “generally recognized as safe.” Sodium phosphate helps meat retain moisture so it doesn’t dry out. Carrageenan, derived from seaweed, improves texture and binds water. They’re extremely common across the food industry. But the plaintiffs argue these additives function like preservatives, which would make Costco’s “no preservatives” label misleading. Their attorney put it plainly: “Costco’s own ingredient list contradicts its marketing.”
The suit alleges violations of consumer protection laws in California and Washington and seeks restitution and changes to labeling. Costco hasn’t directly contested the claims in court yet, but the company did tell USA Today that it has removed the “no preservatives” language from its rotisserie chicken signage and online materials. Whether that’s an admission or just a precaution — you can draw your own conclusions.
Costco shoppers are surprisingly unbothered
Here’s the funny part. Despite the lawsuit and the food safety data, Costco’s customer base doesn’t seem particularly rattled. Reddit threads about the labeling lawsuit are filled with responses that range from resigned to defiant. “Of course, someone has to ruin it for everyone else,” one user wrote. “Lawsuits are expensive to defend. Win or lose, Costco is being harmed. And win or lose, the rest of us consumers will end up paying more while greedy lawyers and their ‘clients’ get rich.”
Others were even more blunt. “That chicken is five bucks,” another commenter wrote. “I don’t care.” And honestly? That attitude is hard to argue with from a purely economic standpoint. The $4.99 rotisserie chicken is one of the last truly cheap meals in American retail. It feeds a family. It stretches into tacos, soups, sandwiches. People aren’t buying it because they think it’s health food — they’re buying it because it works. The loyalty is less about the chicken itself and more about what it represents: one thing in your life that hasn’t gotten more expensive.
What you should actually do about all this
Nobody’s saying you have to stop buying the chicken. But it’s worth being smart about it. The rotisserie birds are fully cooked before sale, and proper cooking does kill salmonella. The bigger risk is cross-contamination — bringing raw chicken home from the same supply chain and handling it carelessly in your kitchen. Food safety basics still apply: wash your hands, keep cutting boards clean, refrigerate leftovers promptly, and eat them within three or four days.
If you’re reheating leftover rotisserie chicken, bring it to an internal temperature of 165°F. That eliminates bacteria. And if you’re buying Kirkland Signature raw chicken breasts from Costco, maybe be extra careful about how you handle and cook them given the plant’s track record. No confirmed widespread outbreak has been linked directly to the rotisserie chicken itself, which is genuinely good news. But the contamination data from the LPP plant is real, and raw products from that facility carry more risk than the industry average.
As for the preservative lawsuit, it probably won’t affect your dinner plans tonight. The case is in its early stages, no rulings have been made, and sodium phosphate and carrageenan aren’t exactly scary chemicals — they’re in a huge number of processed foods you already eat. The legal question is really about labeling accuracy, not safety. Though some studies have raised concerns about carrageenan and digestive irritation, and high phosphate intake can be an issue for people with kidney disease, these aren’t ingredients that should keep most people up at night.
Costco’s $4.99 chicken isn’t going anywhere — at least not yet. No regulatory order has been issued. No recall is in play. Lincoln Premium Poultry has stated that the facility “treats the safety of its products as an utmost concern” and “will continue to improve our processes,” though neither the plant nor Costco has publicly outlined any specific corrective steps tied to the contamination data. The chicken stays on the shelf, and 157 million birds a year keep rolling out the door.
Maybe the strangest thing about all of this is how it mirrors a pattern we see with a lot of cheap, popular products. The price is kept low. Consumers love it. And nobody looks too hard at the machinery behind the curtain — until someone forces them to. The real question isn’t whether Costco’s rotisserie chicken is safe to eat tonight. It probably is. The real question is what it means that we’ve built a food system where a federally failing plant can keep shipping product to stores indefinitely, and the only entity with the power to stop it is the company making money from the sales.
