Hi -

If a product is marked kosher PARVE, then it contains no milk-dreived
um, DERived ... products and no products from any part of an animal
EXCEPT that it may contain eggs and egg-derived products.  Depending
upon the details of the certifying organization, it may also contain
fish and fish-derived products.  But certainly nothing derived from
any part of a land animal.

My web page contains some further details on kosher markings, as they
pertain to people with dairy allergy.

I hope this helps,
