Regulatory context
FDA matching stays visible after launch.
Manual disposition found brand-relevant Hill’s recalls in 2019 and 2014, with no brand-relevant FDA recall in the five-year archive window. A Canyon Bakehouse bread row was dismissed as out of scope.
Direct FDA warning-letter source confirms a 2019 Hill’s Pet Nutrition warning letter tied to canned dog food vitamin D recalls and preventive-control violations. FDA’s related recall alert says the canned dog food recall was terminated on December 21, 2021. Keep active-warning-letter signal unknown because no closeout letter was captured and full warning-letter export coverage remains incomplete.
