If you are packaging fish using a reduced-oxygen packaging method (ROP), the fish must include a label stating what?

If your operation is packaging fish using reduced-oxygen packaging (ROP), the fish must be frozen before, during, or after the packaging. And it must also include a label stating that the fish must remain frozen until it is used. If your operation is using frozen fish from a supplier that has packaged it by ROP, it should usually remain frozen until it is used. And the package should be inspected for a label containing instructions for thawing the fish and if the fish should be removed from the package before, during, or after thawing.
