§  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.
