This checklist verifies pet and specialty pet food labels against requirements codified in state feed control laws and federal regulations (21 CFR), using the AAFCO Model Bill section numbering (PF2, PF3, etc.) as a convenient cross-reference framework. It does not reference the AAFCO Official Publication directly, as licensing terms for that copyrighted material have not yet been established. Each check can be toggled on/off, filtered by feed type and regulation version, and extended with unlimited custom rules.
