New York Consolidated Laws, Agriculture and Markets Law - AGM § 201-a. Kosher food and food products; packaging

1. All food and food products packaged in any container and sold or offered for sale as “kosher” or “kosher for passover” shall have a “kosher” or “kosher for passover” label affixed by the manufacturer or packer at its premises. No person other than such manufacturer or packer shall affix such labels.

2. All food or food products that are not packaged in a container and are sold or offered for sale as “kosher” or “kosher for passover” shall have a “kosher” or “kosher for passover” label affixed thereto. No person other than such manufacturer or packer shall affix such labels.

3. Any food or food product in package form that is certified or labeled as “kosher” or “kosher for passover” shall not be sold or offered for sale by the producer or distributor of such food or food product until the producer or the distributor shall have registered with the department the name, current address and telephone number of the person certifying the food as kosher.

4. Any food or food product in package form that is marked “rabbinical supervision” or that is marked with a “k”, “km”, “kos”, “kp” or any other generic marking used to convey that such food or food product is kosher, except a registered trademark not used to represent such food or food product as kosher, shall not be sold or offered for sale by the producer or distributor of such food or food product until such producer or distributor shall have registered with the department the name, current address and telephone number of the person certifying the food or food product as kosher.

5. As used in this section, the term “food or food product in package form” means a food or food product not intended for consumption at the point of manufacture that is put up or packaged in any manner in advance of sale in units suitable for retail sale.

6. Any advertisement for food or food products representing that such food or food products are kosher shall identify the name of the person, or entity, certifying such food or food products as kosher.

7. Where a producer or distributor is required to register a certifying person pursuant to the provisions of this section, such producer or distributor shall immediately notify the department of any change in the registration information.

8. No liability for misrepresentation shall be incurred by any distributor if it has received written representation from a manufacturer of food and food products that its certifying information has been filed with the commissioner; provided, however, that if such distributor has received notice from the commissioner that the information filed by such manufacturer is no longer valid, the distributor will be liable for the sale of misrepresented products unless the distributor files valid certifying information.
