This Manischewitz chicken broth has an OU, but it has the disclaimer “Not for Passover Use”. The ingredients in this are: Chicken stock (water, chicken), salt, flavorings, chicken fat, yeast extract, sugar, vegetable juice concentrates (carrot, celery, onion).
Would this be kosher for Pesah or not?
