| | MEAT PROCESSING, NORTH AMERICAN: Controlling Listeria Vectors |
 | | With Listeria having a strong ability to survive in such a variety of in-plant conditions, the higher-log reduction, the better. | | | So controlling the byways and pathways pathogens use to get in touch with each other for community-building is an excellent – and critical – way to keep processing food-safe. | | | The movements of Listeria monocytogenes are particularly difficult to control, however. |

| | Cancer Vaccine Based On Pathogenic Listeria Bacteria Shows Promise Targeting Metastases |
| | "These studies address one of the major barriers to using listeria therapeutically, which is, how you create a strain that is safe enough to move forward into the clinic," said David Cook, vice president of research and development for Cerus. | | | "Listeria not only stimulates this additional innate immune response, but it also puts the antigen into exactly the pathway we want and gives us a robust antigen-specific response." | | | Listeria is ideal as a vehicle for cancer vaccines because it normally induces a strong innate immune response in humans as well as a potent induced immune response. |
