Nori

NORI IS KNOWN TO be prone to infestation, which affects its kosher status. Sea creatures such as sea horses and tiny shrimp can get caught in seaweed and can end up mixed in the product. The level of infestation varies depending on the time of the year (typically decreasing in the colder months) and depends on the processing methods used.

Although manufacturers use scanning devices to inspect nori sheets for imperfections, our experience has shown that these scanners often fail to detect the tiny sea creatures, as they blend in with the natural color and texture of the nori.

For this reason, nori always requires a reliable hechsher.

In OK certified nori production, we ensure that effective systems are in place to prevent infestation and finished products are subject to regular sample inspections to verify that they are free of infestation.

Additionally, there are potential kashrus concerns related to the equipment used. Flavored seaweed that includes non-kosher flavoring can be processed on the same equipment. This is yet another reason nori must be certified kosher.
