What Is a Kosher Certificate and Why Does It Matter?

Kosher means 'fit' or 'proper' in Hebrew and indicates that a food may be consumed according to Jewish religious law, kashrut. A kosher certificate is the document showing that an authorized body has inspected and approved a product's ingredients, production line and equipment for compliance with these rules.

The core principles of kashrut include permitted and forbidden animals, a specific method of slaughter (shechita) and, above all, the strict separation of meat and dairy. For this reason a product resembling halal is not automatically kosher; the process requires separate expertise.

A kosher certificate is not only a religious requirement but also a strong mark of quality and trust. Because the strict audit reveals exactly what is in a product, many non-kosher consumers (vegetarians, the lactose-sensitive, people with allergies) also prefer the kosher logo as a sign of transparency.
