Has Hill's Prescription Diet ever been recalled?

No Hill's Prescription Diet products match any FDA recall in our tracked feed. Two caveats worth stating plainly: our feed covers FDA recall notices from late 2025 onward, so a recall older than that would not appear here; and brand matching is deliberately conservative, so a recall naming a parent company or a co-manufacturer rather than Hill's Prescription Diet itself may not be linked. For a definitive answer, check the FDA's own recall database.
