Carnobacterium  Carnobacterium is a genus of Gram-positive bacteria within the family Carnobacteriaceae. "C. divergens" and "C. maltaromaticum" are found in the wild and in food products and can grow anaerobically. These species are not known to be pathogenic in humans, but may cause disease in fish. A species of "Carnobacterium", "C. maltaromaticum" strain CB1, has been evaluated under the Canadian Environmental Protection Act, 1999, as a food additive for vacuum- or modified atmosphere-packaged ready-to-eat meat and fresh comminuted, processed meat. Based on the hazard and exposure considerations, the risk assessment conducted by Health Canada concluded that "C. maltaromaticum" strain CB1 is not considered to be toxic to the Canadian environment or human health as described in Section 64 of CEPA 1999.
