Is Costco chicken washed in chlorine?
Is Costco chicken washed in chlorine? Costco’s reviewed public disclosures do not establish the wash agent for a particular package or rotisserie chicken.
Its 2025 sustainability report describes air chilling at Lincoln Premium Poultry in Fremont, Nebraska. The report connects that facility to select Kirkland Signature poultry, including rotisserie demand; it does not cover every Costco chicken supplier. Air chilling describes cooling and does not identify every earlier antimicrobial treatment. Keep raw and cooked products separate when checking the evidence. Neither the Costco name nor a rotisserie label settles the processing question. Match the exact product and its dated package information before applying a plant-specific statement to it.
The report supports the LPP cooling statement. It does not establish a current wash policy for every Costco chicken product.

Is Costco rotisserie chicken chlorine-washed?
No wash-agent statement was located in the reviewed Costco report. Its LPP and rotisserie references do not identify every bird’s earlier treatment. Cooking and antimicrobial processing are separate steps.
Does Costco’s air chilling prove chlorine-free processing?
No. It identifies a cooling method at the named facility, not the complete processing history of all Costco chicken.
