Ya Ya Foods USA, LLC
Outcome
FDA issued a warning letter on September 24, 2024, after inspecting Ya Ya Foods USA's aseptic LACF processing facility in Ogden, Utah (which produces Oatly-brand oat milk), finding failures to monitor critical sterilization temperatures, inadequate recording of aseptic process deviations, and steam supply shortfalls rendering products potentially adulterated.

Ya Ya Foods USA, LLC — LACF Process Deviations / Oatly Oat Milk / FDA Warning Letter (2024)
Outcome: FDA issued a warning letter on September 24, 2024, after a May 2024 inspection of Ya Ya Foods USA's Ogden, Utah aseptic processing facility found failures to monitor and document critical sterilization temperatures, deviations from scheduled low-acid canned food (LACF) processing controls, and a steam supply shortfall creating sterility risk in its Oatly-brand oat milk production line.
Ya Ya Foods USA, LLC operates a LACF aseptic processing facility at 450 Depot Drive, Ogden, Utah 84404, which manufactures and packages aseptically processed oat milk beverages under contract for Oatly, one of the nation's leading plant-based beverage brands. FDA inspectors visited the facility from May 13–16, 2024, and found serious violations of the Emergency Permit Control regulation and LACF thermally processed food regulations at 21 CFR Parts 113 and 108.
The warning letter identified multiple critical process control failures: (1) the firm did not identify deviations from its scheduled aseptic process or monitor critical factors when they went out of control; (2) the temperature of sterile seals and barriers was observed below critical parameters and below the boiling point of water during production — a condition that can allow microbial contamination to breach the sterile barrier; (3) recording procedures for aseptic process parameters were inadequate; and (4) investigators observed that the facility's ongoing plant expansion had increased steam demand beyond the facility's steam supply capacity, creating conditions where validated thermal processing schedules could not be consistently executed.
Failure to maintain the critical parameters in LACF aseptic processing creates risk of survival of Clostridium botulinum spores — a pathogen capable of producing the lethal botulinum toxin in sealed, low-acid products stored at room temperature. The FDA's warning letter required corrective action within 15 working days.

How Crucible Prevents This
The steam supply shortfall during plant expansion is a textbook example of an infrastructure change creating an untracked food safety hazard. Crucible's DECISIONS log — requiring documented change-management review before major facility modifications — would require the firm to assess whether the plant expansion altered the steam capacity required for validated thermal processing schedules, and document that assessment before production resumed at expanded capacity. The unidentified process deviations represent exactly the class of compliance gap that systematic session-gate review catches.
