Our nori used to be certified kosher but is no longer. The product has not changed. What has changed is the standard our kosher certifier uses when evaluating the product. The evaluation process now includes examination by microscope for crustaceous substances, when it hadn't before. As you may already know, our Emerald Cove nori is grown in the open ocean. As one could imagine it is impossible to separate the animals that live in the sea - including crustaceans - from the nori crop. Because we cannot guarantee that we will pass the new microscope test 100% of the time, we made the decision to cease kosher certification for our nori.
