Important Disclaimer

This tool does NOT certify products as kosher. It only checks ingredient lists from Open Food Facts against known non-kosher items. It does not verify:

• Kosher certification symbols (hechsher)
• Processing equipment or facility status
• Handling, transport, or cross-contamination
• Whether ingredients are actually animal-derived

Always check the physical product packaging for a recognized kosher symbol. When in doubt, consult a qualified rabbi.
