5 Disadvantages Of Buying A Costco Rotisserie Chicken

If rising grocery bills have you signing up for a Costco membership for the first time, the Kirkland Signature Seasoned Rotisserie Chicken can really grab your attention. Snag one of these ready-to-eat chickens, and there's no need to cook dinner after a day filling a cart with Costco's bulk bargains. And at $4.99, Costco's whole rotisserie chickens cost roughly half the price of a raw bird.

After that evening's meal, the purchase can be stretched even further. Leftover rotisserie chicken feels fresh again in next-day sandwiches, enchiladas, or chicken nuggets that beat your favorite fast food. Even Costco does the same in store, reducing waste and expense. The cooked chickens are hot for sale for just two hours, after which they are repurposed into deli items like pot pies or chicken noodle soup.

Unfortunately, Costco's rotisserie chickens are far from perfect. Before purchasing one during you next visit, beware of these disadvantages of Costco's rotisserie chicken.

Costco has been selling its Kirkland Signature Seasoned Rotisserie Chicken since 1994. For decades, Costco had packaged the chicken in hard-plastic clamshells. That changed in 2024 when Costco dropped the shells in favor of sealed plastic bags. Costco claims that the new packaging greatly reduces plastic waste, and while that may be true, many customers aren't pleased about it.

A TikTok video critical of the bags attracted several comments from Costco members looking to vent. The video reveals condensation inside the bag, and a highly liked comment said the bag "makes the crispy skin soggy." The most common complaint about the shift in packaging is that the plastic bags are greasy from improper seals and leak chicken juice everywhere. Even if your rotisserie chicken makes it home without splattering the trunk of your car, don't store the chicken in the bag it's sold in, or risk unfortunate incidents with the poultry at home.

Costco warehouse stores are massive. Besides the towers of bulk pantry and household goods, Costco sells everything from fresh groceries to television sets to diamond rings. If a rotisserie chicken is snagged on the earlier side of a shopping trip, it could spend over an hour slowly cooling in a shopping cart. Then there's the ride home and the time on the counter while the other groceries are being unloaded. All that time neither in the oven or the refrigerator could place that chicken in the danger zone.

The danger zone is the temperature range where bacteria most loves to rapidly reproduce inside the uncooked flesh of raw meat. Meat resting between 88 to 140 degrees Fahrenheit may host Salmonella, E.coli or Staphylococcus bacteria that can double in number in 20 minutes. That means a meal that will lead to a swift case of food poisoning and all the unfortunate symptoms that come with it.

Costco advertises that the chicken it sells is preservative free, but a class action lawsuit filed in California in January 2026 claims that's not true. The complainants allege that Costco's rotisserie chicken contains both sodium phosphate and carrageenan. The questions is: Are they preservatives? Costco argues that they are used in the rotisserie chicken's seasoned brine to help keep the meat tender and moist.

Neither additive is classified as a preservative by the FDA, although sodium phosphate can reduce the oxidation of fat, which helps keep the meat from going rancid. Carrageenan's primary purpose is to retain water, and whether or not it's a preservative, it still makes some people nervous.

A 2024 study suggests that depending on certain conditions of a person's intestines, carrageenan may potentially cause inflammation, reduced glucose tolerance, and leaky gut. All is which to say it might make some people feel sick.

Most of Costco's broilers are processed by Costco's exclusive poultry supplier, Lincoln Premium Poultry in Nebraska. With full control of every stage of the livestock's development, Costco reduces expenses and breed larger than average birds as well. That means the consumer gets more meat for less money. It's sad to say, but suffering chickens might play a part in that deal.

In 2021, the advocacy group Mercy for Animals sent an undercover investigator to one of the Nebraska farms responsible for fulfilling Costco's immense demand for chicken. The investigator found penned-in chickens packed together so tightly that their wings overlapped. Specially bred to grow huge breasts, some birds were so top heavy they would fall over and stay down, too overburdened to climb out of their own droppings.

Costco has publicly committed to improve the birds' nutrition, environment, health, behavior and mental state in accordance with the Five Domains Model for animal welfare assessment. Mercy For Animals claims to have still found harmful conditions in a 2026 investigation into one of Costco's organic chicken suppliers. If all this inspires you to shop for higher welfare animal products, make sure to be informed of what the different labels actually stand for. "Free range chicken" may not mean what you think it does.

Costco sells over 100 million rotisserie chickens a year, so these ready-to-eat birds clearly have their fans. But renowned chef David Chang isn't one of them. On a 2023 episode of his podcast, the Fuku fried chicken shop founder declared that "Costco chicken is the worst rotisserie chicken," and "inedible." But you don't need to take a celebrity restaurateur's word for it.

A commenter on the r/Costco subreddit said the chicken at their local Costco has "a weird chemical taste, so I quit buying them." On another thread, a poster uploaded a photo of a cooked chicken with visibly green tissue that they claimed came from Costco. If you find yourself rethinking your next purchase of a ready-to-eat rotisserie chicken from Costco, maybe try one of the others from this list of seven grocery store rotisserie chickens, ranked from worst to best.
